TomTom, TeleAtlas and MapShare

August 29th, 2010 by MDob

Recently, I spoke with Patrick McDevitt, Vice President of Community Mapping at TomTom, who reached out to discuss the company’s view on the value of the MapShare and probe data gathered by users of TomTom’s Personal Navigation Devices.

Patrick has been around the world of mapping for quite some time, having earned his merit points with Tele Atlas and GDT. My interest in having the conversation was to explore the benefits that accrued to map database augmentation through the use of TomTom’s crowdsourced data and to explore the company’s strategy related to the use of these data.

I suppose you noted my use of the phrase “the company’s strategy” instead of indicating Tele Atlas, as it seems that Tele Atlas, as we know it, is slowly being absorbed into the corporate identity of TomTom. Indeed, if you look at the Tele Atlas website home page you will read that “Tele Atlas is the licensing business unit of TomTom N.V., the world’s leading provider of location and navigation solutions.” I will comment on the outlook for TomTom at the end of today’s blog, but want to separate that discussion, which includes thoughts that are solely mine, from my conversation with Pat, as we purposefully limited our discussion to issues related to MapShare and crowdsourcing.

I requested that Pat give me his “elevator pitch”, as a way of starting our conversation about Tele Atlas and its introduction to crowdsourcing. Here it is (without the elevator music) – Shortly after closing the acquisition of Tele Atlas, TomTom indicated to TA that they had a new source of mapping information called MapShare. TomTom thought MapShare would be quite helpful in updating the TA map database. In turn, Tele Atlas was skeptical that user input could be of significant benefit to map creation and updating process. However, that did not stop TomTom from saying “Here are your first million observations – let’s see what you can do with them.”

Previous to this, TomTom received community input in the form of map edits (corrections and augmentations) from users of MapShare who could indicate whether they wanted to share the data with the TomTom MapShare community. If so, TomTom attempted to verify the information and, if verified, it was added to the community (MapShare) version of the navigation database and distributed to users.

McDevitt indicated that the initial skepticism at Tele Atlas regarding the potential quality of the MapShare data soon transformed into intrigue over the data’s possibilities and eventually evolved to evangelism. While Tele Atlas understands that there are limitations to the data supplied by MapShare, they also believe that it is an exceptional tool for identifying change detection, especially for map updates that are hard to discover otherwise.

Once we had progressed through the elevator pitch, Pat indicated that it took Tele Atlas most of twelve months to understand how to use crowdsourcing to advantage the Tele Atlas map database. By 2009, TA felt that they knew how to use the crowdsourced data and added the technique to their standard arsenal of map compilation and updating tools.

Tele Atlas has two streams of community input. Active Community input, using MapShare, involves users purposefully interacting with the PND and providing input about errors found in the version of the map database resident on their device. Passive community input involves the user of a TomTom navigation platform agreeing to allow traces of the GPS positions and paths recorded by their TomTom PND to be anonymously uploaded through the TomTom Home software to the TomTom mother ship. TomTom Home is an application that resides on the user’s laptop or desktop computer that is activated when the user docks his navigation device to the computer. I asked Pat about the take rate and he indicated that “most” customers give their assent to allow the company to use their anonymous GPS data to improve the Tele Atlas map database. (Hmmm. I may be the lone exception.)

Pat acknowledged that Tele Atlas originally was hoping that the passive community data would help them to create street centerlines that were more accurate than those then in their database. However, Tele Atlas had concerns that potential problems with the quality of the GPS data collected (due to the performance characteristics of the GPS receivers and the influence of other factors such as signal scatter, foliage, urban canyons, etc.) could degrade the utility of the data. In fact, they were sure that the GPS readings collected from TomTom PNDs would be less accurate than the positional data captured by the Tele Atlas fleet of mobile mapping vans. What they had not appreciated, at the start of the venture, was that aggregating a massive number of data points collected over time would help them average out errors and create a database with an extremely high level of positional accuracy.

I was told that the company’s MapShare community input has now produced over two trillion GPS points that are being used to improve the quality of the Tele Atlas map database. In addition, Tele Atlas is now using the MapShare GPS traces in an attempt to create other kinds of map attributes, such as road gradients, road curvature and other high accuracy data that might be of interest to the Advanced Driver Assistance Systems (ADAS) community.

In a previous conversation I had with Chris Wilson, one of the thought leaders at Tele Atlas focused on ADAS, he indicated that the passive community data might have significant benefit as behavioral data for ADAS. For example, it might not be necessary to compute the shape of a curve and calculate a metric for a “curve speed warning” system, when, instead, you could provide a history of the speed that the curve could be driven safely, perhaps even by season or by driver profile, as recorded by tens of thousands of drivers.

Most people have an easy time visualizing what the paths of probes would look like on a map, but I thought that several of the illustrations used by Pat during our conversation might be of interest to you. Our conversation was augmented by an online presentation. The images shown during the online segment were low resolution JPEGs and I apologize in advance that my copies are even fuzzier. However, you should be able to glean the important issue, even though parts of the images will not be readable due to the size of the images. The images do not have legends that you can read, so go with the general notion that the brighter the colors, the more probe paths recorded.

Probe patterns and density in Laguna Niguel, CA

The image above overlays a “heat map” of the paths of cars equipped with TomTom PNDs crisscrossing the transportation network in a section of Laguna Niguel near my home in California. The bright north-south lineation is the I-5 freeway connecting Los Angeles with San Diego. The east west arterial is Crown Valley Parkway, while the curved road in the lower left is the 73 Toll Road. On the right you can see the traffic patterns around a local mall. The remainder of the area is an industrial park with relatively light traffic.

extractions of center line data from probe traces

In this example from Huntington Beach, California you can see that the probe data is capable of providing lane directionality along major streets. Some of the probe data is in very light colors that do not show up well on my copy of the image.

Probe traces erupt from Best Buy

As you know, I beat on Tele Atlas (and everyone else) about their missing the I-195 realignment in Providence, Rhode Island. I asked Pat how TA had missed this change since they must have had units crossing the bridge before and after the realignment. He acknowledged that this was true and offered one of those explanations that cause management to shoot themselves in the ear! (Don’t tell me you haven’t seen those guys on the street with the big holes in their ears. Ex-technology executives, every one of them! Those hoops are just a disguise.)

The staff at Tele Atlas believed that the strength of the probe data was in aggregating the paths for a location over time in order to average out the errors and increase the accuracy of the observations. However, when I-195 was realigned, the massive amount of data that had been collected for the pre-realignment geometry caused the smaller number of traces recorded for the geometry of the “new” highway to be “averaged out”, leaving the old geometry king of the road, at least, in statistical terms. Below you can see the same location shown in an image that has been time-sliced. The probe data for the pre-realignment geometry is shown in brown and clearly visible, while the vibrant green color shows the new paths of the intersecting highways. Needless to say, time-slicing has now become part of the Tele Atlas strategy for interrogating their probe data.

Providence probe data time sliced

TomTom continues to use imagery and other sources for revising their map base and has found that local probe data is a good way to evaluate imagery, indicating whether the imagery is current in terms of the transportation network or needs to be supplemented with other research sources. In the illustration below, you can see that the probe data shows a number of streets that do not appear on the reference imagery.

New roads date older imagery

Don’t get the idea that Tele Atlas is focused on the probe data alone, as the next two illustration show reports from active community input, in which MapShare users have indicated that a road that used to be a four-way intersection is now a roundabout.

A roundabout reported through MapShare

In the second “active” MapShare example shown below, users indicated that the TA map was incorrect and missing a street. Not only did the MapShare users note the error, but they also provided the correct name for the street. The probe data (passive community data – shown on the bottom right of the image) also provided evidence of the street. All information was verified by TomTom researchers before it was added to the database.

TA uses both active and passive community sources as change detection indicators to help the company’s researchers decide where to focus their efforts related to map updating and source gathering. When possible, Tele Atlas prefers to work with data mining and authoritative sources to remedy issue raise by MapShare input, but says it will deploy field research if required to resolve the issue to their satisfaction.

A missed road that was caught my MapShare contributors

The final image shows the active MapShare community input for localities in California from the first four days in August, 2010. The dots show location where the reported information differs from that contained in the Tele Atlas database. While there is an obvious autocorrelation with population density, it is clear that active community input is a powerful tool for change detection.

MapShare changes in Calif, not in TA database - four day period in August, 2010

I asked Pat about the volumes of data that were being generated through “active” community input and was told that so far in 2010 the top twenty countries, in terms of the volume of reports, have reported over two million change notices. Note, these are not passive GPS traces, but instances where someone has taken the time to tap the screen of their TomTom PND to capture the location of the change to be reported and taken the time the indicate the nature of the change. It is my understanding that since the TomTom MapShare program started the company has logged over 80,000,000 “active” reports by MapShare users. In addition, approximately 80,000 TomTom PNDs connect each month to upload “active community data”, although the number of units connecting to TomTom Home for updates and other downloads, is considerably larger.

Pat indicated that the Tele Atlas learning curve for understanding how to use the community data in an effective manner was quite steep. While Tele Atlas appears to have found benefits to using both active and passive community data, it appears to me that they prefer to work with passive data since its “pureness” would generally rule out malicious intent on the part of the contributor. When I asked about malicious intent, Pat responded that Tele Atlas has learned how to manage active community data and ferret out potential “problems” in MapShare inputs that appear designed to obfuscate information. I was surprised to learn that among the “tricks” they had found in the “active” data were instances of users living in neighborhoods plagued by speeders posting MapShare edits indicating that the speed limits around their homes are lower than officially posted. Their intent was presumably to have these bogus speed limits uploaded and provided to other TomTom MapShare users who might be driving too fast in their neighborhood.

McDevitt felt that the threshold to build out a map at Tele Atlas is falling, due the advantages provide by community input through MapShare. He gave the example that Tele Atlas did not have good access to comprehensive data in Romania, but was able to build a basic road network interconnecting major towns and numerous locations outside of the country through its MapShare customers who had driven through the country with their TomTom’s operating. The MapShare community took these data, edited them and helped to create a new map with some significant features, although the data was not comprehensive enough to add to the Tele Atlas navigation database.

One area where passive community data shines is in collecting data on traffic and travel time, which are areas that obviously benefit from probe data. In addition, Tele Atlas is working to determine whether they can extract lane count from the passive community data. They feel that their efforts are getting within striking distance of the results that they can derive from imagery and the lane data collected by their mobile mapping vans. Pat indicated that current test revealed an accuracy of 80% to 85% in lane counts for multi-lane roads using the passive community data uploaded by MapShare users.

I asked Pat his thoughts about the company’s mobile mapping vans and whether they still provided value. He indicated that the mobile mapping vans were now used for higher-end products and that the company had learned to be more purposeful in the types of problems they were deployed to resolve. Sending the mobile mapping vans to the field as a primary source to collect all road related data is just too expensive. Instead, the company culls all user reports and MapShare data to determine where deploying the vans is optimal and where surrogate sources will provide acceptable results.

I related my observation that for a period after the acquisition of GDT by Tele Atlas, the two companies seemed to speak with a forked tongue related to field work. I mentioned an occasion when the TA North America president issued a press release indicating the strength of the company’s data mining activities and their desire to go into the field only when forced to do so. Unfortunately, the same day, Tele Atlas corporate headquarters issued a press release indicating that they had just deployed a new generation of vans that would allow them to collect more field data a faster pace than ever before. Pat responded with the observation that, in the past, GDT (and Tele Atlas, North America) may have done too much data mining, but still feels that data mining makes sense in the United States and that the situation is now beginning to change in Europe (with programs such as Inspire, etc.,). However, he noted that the community input from MapShare has changed the game, as it provides a useful surrogate indicating the location of problem areas all allowing an evaluation of the best method for gathering the needed data.

When I asked about the competitive threat from OpenStreetMap, Pat replied that the “map geeks” at Tele Atlas (and he is one) celebrate map geekiness and OSM. However, he indicated that their clients are willing to pay for Tele Atlas data because of their need for verification and double checking of the data. He continued, noting that it was his belief that there are clients whose data quality needs can be best met by the high level of authoritative map data that Tele Atlas is able to provide.

I ended the conversation with a “pregnant” question, which was “ If Tele Atlas and TomTom depend on MapShare data to help increase the accuracy of their map base and reduce the expense of keeping it up-to-date, are they experiencing declines in the amount of data customers provide through MapShare?” Pat indicated that the company does not have a “dwindling amount of data” problem. He related that there was a continued interest by customers in all platforms. In addition, TomTom’s newer programs such as Traffic HD and TomTom Work (a logistics solution) are increasingly popular with customers worldwide. Pat noted that TomTom has experienced quite a bit of success getting devices into cars, as is shown by their collaboration with Renault (Carminat). He also noted that the TomTom iPhone device is not cannibalizing other TomTom products or services. In sum, the data just keeps rolling in and TomTom appears to have a tool that is the best of class in the industry.

Now you know some of what I heard from Pat McDevitt of TomTom

And Now For an Additional Perspective

I have long thought that TomTom’s MapShare should be a powerful differentiator in the navigation database market and that the quality of the Tele Atlas database should increase as some function of the number of active inputs and passive GPS points and traces contributed by the TomTom user community. My conversation with Pat McDevitt helped me to understand that it may have taken Tele Atlas longer to harness the benefits of community data than I had suspected. However, it seems to me that the evidence leads one to conclude that the company is now far along the learning curve posed by community sourced data.

While it seems clear that TomTom is figuring out how to use the data to benefit the accuracy and comprehensiveness of their database, it also appears that the popular reaction to the acquisition of Tele Atlas by TomTom seems to be turning antagonistic. Indeed, many industry analysts seem ready to conclude that the merger of the two companies has failed to produce the desired benefits.

I think these prognostications are premature. While it may have taken longer than thought to see the advantages of the merger, I believe that there is no other company better positioned than TomTom to benefit from owning Tele Atlas. While some financial analysts seems to feel that TA is available for the right price (what isn’t?), I can’t imagine that TomTom would feel that any price was the right price, unless they were planning to close the company and count money as a profession. However, I don’t think that is the plan, although it sounds good to me. MapShare has value to TomTom, but what would TomTom do with MapShare and no Tele Atlas? And what would Tele Atlas now do without MapShare? However, at TomTom’s present value someone might be enticed to buy the combined entity and regard it as a fair price for Tele Atlas. If this is the strategy, they had better be prepared to compete in the automobile navigation market or kiss their investment in the navigation hardware business goodbye.

While I appreciate that there are several companies out there who are potentially interested in being in the map business, most of them lack an understanding of the process required to build and maintain a navigation map database with competitive coverage and accuracy. In addition, most of the companies who think they are interested in owning a navigable map database company, are interested in owning maps that can be used to pimp their advertising business and have no idea what it is like to compete to provide systems and services to the navigation segment of the automobile market (including ADAS). On the other hand, if these companies are willing to abandon these markets, won’t NAVTEQ be happy? Well, this blog it already too long without going into potential acquirers, but look east, Far East (or west from California, where I write this blog).

Speaking of NAVTEQ, now that TomTom has shared some information with me, do you suppose NAVTEQ would be willing to give me a ride in one of their new, super-duper, Dilithium crystal powered mapping vans? Last January I received an email from one of NAVTEQ’s PR flacks (sorry – but it was not a person who worked for NAVTEQ) who had noticed my blog and invited me to take a ride with one of the company’s data research teams to see how they gathered data. I replied that I would love to take them up on their offer, but that for their own good, they should probably take this issue up with NAVTEQ’s senior management, as, from time to time, I had criticized NAVTEQ (and everyone else in the industry) just a tiny bit in my blog.

The response? I’ll bet you guessed. I received…silence (although, I was happy about that since I was told by my Mother that silence was golden). I waited a week and being something of a pest, wrote again asking for a response. Fate was cruel, however, and several days later I received an email rescinding the previous offer, but thanking me for my interest (even though I had not initiated the exchange). However, the author of the email did suggest it might be better to wait until later in the year when NAVTEQ’s new generation of vans was available. Hmmmm. I think I saw one of those new platforms parked outside the San Diego Convention Center at the ESRI show in… July. Perhaps they forgot about me? Do you suppose an offer is forthcoming? Man, Dilithium crystals – I can’t wait. Larry? Roy?

Speaking of ESRI, I am thinking about writing about their new Community Map program in the next month or two. I know that nobody will believe me, but I am beginning to thank my stars that ESRI exists and you should too. More about that claim in a future blog.

Better Maps Through Local Thinking – Conclusion

August 10th, 2010 by MDob

Is it possible that the failure of national, street-level, navigable databases companies to provide robust, quality spatial data across the breadth of their database coverage might serve as the impetus for the development of street map companies focused on producing navigable map databases of local or regional areas? After reading the two previous installments on this topic, you only have to read this one to end it all. Aren’t we glad!

Many believe that all efforts at mapping are fatally flawed and that the degree of failure increases exponentially as the size of the area mapped increases. I suppose this is true, since the data necessary to represent a place may include a near-infinite number of observations. However, if we stipulate that what we want to build is a database for navigation across a limited spatial domain, such as a city or county, we have made the problem more digestible and, at least theoretically, less likely to be as erroneous as similar attempts across larger domains, such as nations or continents.

When most people use maps and navigation databases, they assume that the quality of the database is uniform across the extent of the coverage. However, this simply is not the case. Places that are “established” as more important than others will generally have accurate and current maps. Places that are rated as “less” important will generally be updated less thoroughly and less frequently than locations considered more important.

Even though a hierarchy of preferential treatment exists in the world of commercial mapping, it can be quite unstructured in practice. Usually everyone in top management has a favorite, though little known place, that they visit from time to time and the researchers will hear about the errors in the map of this location until they get it right. In addition, key customers will complain if there are problems in the areas where they have test tracks or in areas used for testing by key customers (of course this includes the areas around their offices) and so on. However, the major producers of navigable map databases actively attempt to harmonize the quality of their spatial data across the coverages they offer and it is this discipline that distinguishes the players from the pretenders in the world of maps and mapping.

In part, it is the active attempt to maintain consistency and currentness across their database that leads to some providers of navigation map databases being considered authoritative. However, being authoritative may not be the same as being correct. We need only look to many of the older USGS quadrangles to realize that some USGS products are both authoritative and inaccurate. Mike Goodchild in his writings on Volunteered Geographic Information (what many would call crowdsourcing or User Generated Content) discusses the difference between “authoritative” and “asserted” data. In today’s world, most creators of map data are asserting that their data is accurate and whether we ever regard these companies as “authoritative” is unclear, although, curiously, most of us do consider them “references”.

So what makes a source authoritative in the world of mapping? One way of thinking is that “authoritative” sources, such as national mapping organizations, set standards, collect data according to these standards and revise their products on a consistent basis so they remain synchronized with the set standards. In the world of commercial navigation database providers, we might consider NAVTEQ and Tele Atlas authoritative sources. Google might be another, although no one seems to know the specific mapping standards to which the company aspires.

In previous blogs, we have contended that “authoritative” producers of navigation databases even though they rely on field data collection crews, instrumented data collection vans, high resolution aerial or satellite imagery and data mining techniques are likely never to get the story quite right. Although data quality is an integral part of the process for NAVTEQ, Tele Atlas and Google, none of these companies can afford to spend unlimited amounts of money in the pursuit of spatial accuracy across the vast spatial domains for which they provide map coverage. Perhaps more importantly, it is unlikely that any of these companies really knows how they measure up against common map accuracy standards. Instead, they do the best that they can in a manner designed to maximize the time value of money, while, hopefully, increasing the integrity of their databases.

The reality is that today’s “authoritative sources” in mapping, although guided by self-imposed data quality standards, field collect what data they can, use imagery to find what they cannot afford to collect in the field and augment their map coverages through data mining. In areas where their teams do not directly collect data through field methods, they attempt to use alternative field-data collection methods, including crowd sourcing and for-hire field representatives (map-temps), but, in the main, rely on imagery and data mining to fill gaps in databases initially built by field observations.

While mapping producers presumably may have a vague ideal of where their data are weak in terms of coverage and quality, it is less clear that they employ useful and diagnostic measures of data quality (e.g. measures that might help them understand which techniques could be used to resolve the specific weaknesses found in their data coverage). Looking at the kinds of errors commonly found in the offerings of the major map and navigation services, it defies imagination that these companies have actually taken the time to develop or perhaps implement overarching data quality measures or practice any type of forensics on their data capture methods and sources.

A couple of years ago, Steve Guptill, a colleague on a current project and friend of mine for quite some time, tried to convince me that we should start a map quality business, an endeavor similar to providing a Good Housekeeping seal on a consumer household goods product. At the time, I told Steve that setting this up would be expensive and difficult to maintain. Today, I think Steve was right, but now we might need to put a tag on a map database similar to Underwriters Laboratories, certifying the database fit for use (you know, something like “low chance of this database producing routes that would kill you”, “moderate chance of it finding where you are going”, “likely chance of geocoding error”, “occasional wrong turn on one-way streets,” etc). But I digress and will simply note that someone needs to establish (not just propose) realistic standards to evaluate the quality of commercial map navigation databases.

Map Compilation

Map compilation models generally can be described as a three- legged stool. The legs of the stool are field data collection, imagery, and data mining. While properly conducted field data collection is the “gold standard” of the mapping world, it is also the most expensive way to gather data. At least one of the major providers does all that it can to keep from sending people in to the field. While this company understands the value of field observations, it has concluded that crowdsourcing, data mining and imagery analysis and are preferable alternatives and that these methods provide a “reasonable” solution with a reduced cost. Others realize the value of the gold standard, but even then cannot afford to apply this technique in as many areas as they would like.

Up-to-date satellite or aerial Imagery is a valuable compilation tool that is an efficient method for finding “missing” elements in map coverages. Unfortunately, imagery provides little in the way of attribute information other than geometry and some clues on potential road class identification. The twin problem in using aerial or satellite imaging is that it is expensive and time-sensitive. It is rare for a mapping company to task an image provider with producing specific coverage just for them. Instead, most rely on the most current off-the-shelf imagery due to cost sensitivities. In addition, economic considerations force these companies to limit coverages imaged by vans and other mobile platforms.

High resolution street-level photography (like Google Street View and the kinds of imagery available from the Tele Atlas vans and the new generation of vans fielded by NAVTEQ) can capture additional attributes such as road width, slope, house addresses, some postal addresses, street names and other information gathered from imaging signs and intersections. While a promising technology, street-level imaging is yet another expensive endeavor, requiring sophisticated technology and the need to train field teams in the deployment of these systems.

Data mining for map compilation takes several forms. In today’s environment, it is considered a discovery process in which online sources of spatial information are interrogated and imported for conflation, presuming these data meet quality standards. In addition, data mining includes the concept of “sourcing”, an omnibus term for the body of spatial data sources that can be discovered by canvassing government agencies, institutes, regional authorities, professional organizations and others entities that may be able to provide leads on useful data.

Each of the compilation sources described above comes with obvious benefits and limitations. However, due to the limitations of these methods, everyone in the mapping business thinks about how to deal with the issue of map updating, knowing that their map coverages are not of uniform quality and that the data collected previously may have changed. In many cases, this means reusing the tools described in the three-legged stool, but with a different perspective.

All map updating is focused on change detection. As a map database producer, you are gratified to know that your data is correct, but, after all, accuracy that is the quality level to which you aspired. Researchers tend to be interested in indicators capable of isolating locations where they did not get it “quite right”, so that they can find it and fix it without having to sift through the entire database in the process. Every major provider of navigable map databases fixes some part of their database each quarter, but they are not interested in looking for things that are correct; they are looking for things that are wrong and change detection is a useful tool for this exploration.

There are many ways to approach change detection (comparing map layers with imagery layers, maps with other maps etc.), but the best approach is to establish a feedback loop with those who actually uses your database for its intended purpose. In fact, this is what Map Share brilliantly accomplishes for TomTom and Tele Atlas. It is used by NAVTEQ in the form of feedback provided by users of their data in the market for logistics. OSM is a sense, is completely based on user feedback, as crowdsourcing most often reflects a users self interest and reflects their desire to have the streets, roads, trails and other paths that they take shown correctly on the maps that they use.

It is my contention that there is no better measure of error in maps built for commercial purposes than consumer complaints. However, lodging a complaint, having it fixed and seeing the result are not common experiences for most users.

The “why’ behind this problem is complex and, in part, may be related to the update schedules of the majors. While Google tries to do a better job of this than others, they have a good record of making valid changes and then changing them back, and forth, and back and forth so many times that those who contribute corrections just give up and use another product. However, one mitigating factor is the size of the problem. Google, NAVTEQ and Tele Atlas are trying to map the world with a high degree of accuracy. Indeed, they have collectively created more, accurate coverage of the world than ever before available. Unfortunately, the size of the endeavor means that they have generated more map errors than have ever been created in the history of map making. While some users will attempt to work with you to correct errors in your data, it is my sense that none of the major producers has yet to get the equation quite right in terms of customer input and customer satisfaction with the process.

One way of looking at the problems that NAVTEQ, Google and Tele Atlas face is to suggest that the mapping errors in their databases are functionally related to the amount of coverage the companies are attempting to map. At some point, it would seem that the energy (personnel, resources, money, etc) they have to expend on the task will fail to resolve the problem. In fact, that is my bottom line for the types of errors that I now see in the databases of the major producers of navigable databases. Perhaps more perilously, except for Tele Atlas, I think consumer sentiment is working against their contributing map corrections to Google and the lack of an obvious, well-advertised venue for contributing map corrections works against NAVTEQ. While I like the TomTom/Tele Atlas approach, it may be that the cost of and preference for buying a TomTom device and using it to advise TA of map errors, limits the audience who will be willing and able contribute information. (On the other hand, TA might say, “Well, we’ve got over two trillion GPS points from Map Share Mike Dobson, how many have you collected from your stinking blog?”)

And Now For the News

Well, by this point, I have probably exhausted you and you are ready to submit. Yep, the best solution to the map accuracy and incomplete coverage problems is to break the universe into numerous, discrete, localized units and make mapping a local business. By reducing coverage to a local area (say a Kansas City, or a Chicago where you might have to cover nine or more counties) you simplify the problem of focus and increase the probability that you can find and leverage local sources to help improve your database. In addition, by developing meaningful relationships with local sources, you will discover information more quickly than your geographically distant competitors.

However, “being local” is only one part of the solution. The other is that you need to make the users in the local area your customers. You need to develop a superior product that is constantly updated. Give your customers a workable crowdsourcing system that allows them to interact with you on their terms and let them help you solve their mapping problems. If you do this, then the local area and its residents, business and governments become your field office.

Everybody has seen the examples of the local company that decided to grow and was so successful at it that it lost its brand identity and its connection with its roots. Usually these businesses fail after a few years and everybody remembers how it used to be. The modern world of mapping is different. Our major companies started large and are growing even larger. They never had a local base and never had the local values that go with it.

I realize that some of you will say, well, I would not be able to use that local company of yours to find out how to navigate in some other city. I agree, but you could use it to find the best routes and most accurate database in the area where you live and spend the majority of your time navigating. Isn’t that a choice you would make if the alternative existed?

I suppose you are chafing and sputtering out ideas on why this would not work. If so, think about this for a second. When the map service that you are using does not work, contains an error and for some reason gets you lost while you are using one of their routes, who do you ask for directions? Do you call Google at 1 Net Neutrality? Or, explain to the 411 operator that you want NAVTEQ customer service? Hah! Well, I ask a local, since they are the only ones around who really know where we are located.

In some sense, this topic on local map databases is yet another example of Waldo Tobler’s First Law of Geography that “Everything is related to everything else, but near things are more related to each other.” You should take a few minutes to think about Waldo’s First Law. It helps explain why “local” mapping could prosper and explains why local should be a low cost, up-to-date solution. Yep, local mapping could trump national mapping and a consortium of local mappers could be an interesting venture. The issue that clouds the future of local mapping is distribution. Of course, with Google and Verizon guiding Net Neutrality, maybe local will never gain the access it would need to be the next new thing.

You know, the only people who should be sputtering about this article are those who believe that OSM is the model I have just described. I am not sure that’s true and may write my explanation in a future blog, but for now, I am sure you are as tired of this topic as I am.

Better Maps Through Local Thinking Part II

July 25th, 2010 by MDob

I started this topic on “Better Maps Through Local Thinking” last time and will finish it next time. Bear with me today, as exploring this topic requires peeling the onion so that we have a common ground for what follows.

Recently, I was driving to San Diego for the ESRI UC, I was listening to the news and a story caught my attention. It seems that a reporter who had bought one of the new Android-based 4G phones from Sprint was enraged that he was being charged an extra $10 per month for 4-G service, even though 4-G service wasn’t available in the Los Angeles area, and might not be until the end of the year. The led me to think that almost everyone who buys PNDs or pay a monthly fee for mobile navigation services often have the same problem.

For example, most PNDs and online navigation services charge you for national map coverage, even if you never use your device anywhere outside of your hometown. I suspect the majority of PNDs are rarely used outside of their home areas or perhaps in an adjacent area encompassing a county or two surrounding their home county. With mobile phones, the use area is larger. Indeed, business users likely use mobile navigation services in a variety of locations, but mostly in locations that are spatially separated from their home base. I doubt that the average user (either PND users or users of mobile phone navigation services) creates routes in any more than two percent of the total area of the United States during the lifespan of the device or their subscription to the service.

The conclusion here is that each user helps reimburse the companies providing their navigation services or devices for offering comprehensive map coverage, even though we rarely use this option. However, the market has convinced us that we are not paying for the original map data. Instead, we are paying for the service and since the service is offered everywhere, we can use it everywhere we happen to be. (Or as quoted by the immortal Buckaroo Banzai “Wherever you go, well, there you are.”) We might conclude that the cost of the product or service reflects its ubiquitousness and our potential, but perhaps unlikely, use-pattern for the service.

In the world of paper maps, the model was slightly different. Yep, there was only one product type, the paper map and usually there were only two piles of maps in stores. One pile included national highway maps, state maps and national road atlases, while the other was comprised of city maps and city map books for various locations around the globe.

If you were going to travel around the US, you bought a US road Atlas from a national provider of maps such as Rand McNally or the AAA. If you were going to Los Angeles, you bought a LA street map or a LA and vicinity map from a national provider such as Gousha or American Map. If you were a resident of Los Angeles, however, you bought a Thomas Guide for Los Angeles County or a combo – Thomas Guide for LA/Orange counties that featured large-scale, up-to-date, comprehensive coverage of the local area. In Washington DC, you bought a map book from ADC. In Austin, Texas, it was Mighty Map, Mapsco in Dallas-Fort Worth and Key Maps in Houston. In Boston, it was Arrow Maps. Do I need to mention that, in the past, the most successful map products in local markets were compiled locally?

Somewhere along the way, somebody convinced us to buy map coverages of places we would never visit. How cool is that? On the other hand, it is clear that the new map databases had attributes that allowed routing and geographical analysis, problems that could not be addressed, in any meaningful way, with paper maps. On the other hand, local companies could solve this problem without much difficulty today.

Interesting stuff, but it is the issue of data quality that should be our focus. Is it possible that local users of map data may not be well served by national or international suppliers of map data who try to optimize coverage, currentness and accuracy across significant extents of the globe? Is it possible that local users are not well served by data based on “global” perspectives that do not embrace and reflect the true nature of place and localities?

In order to get at this issue, let’s explore “how a market in which local maps were produced by local sources changed to an environment in which most map data for use in local markets is produced by national or international sources?”

In the mid-1980’s, the precursor companies to today’s NAVTEQ and Tele Atlas began building commercial, street-level databases aimed at the, then, nascent market for navigation. NAVTEQ’s DCAs are an early example of their approach to segmenting the national market into chunkable areas that reflected markets that might be of interest to automobile manufacturers. However, from Detroit’s perspective it was clear that the market was not going to take off until there was a national product that would allow the car manufacturers to install and sell a navigation system that could be used everywhere. In other words, as some learned the hard way, it was going to be a mistake to produce an in-car system selling for over $3,000, running on a tape cassette, and then say that it only worked in Detroit now and maybe Chicago next year. National data was a must.

Around the same time people were playing with networks, ARPANET, TCP/IP and slightly later NSFnet. In the 90s, we got to the stage of Prodigy, AOL, Netscape, Internet Explorer and all of a sudden there was a perceived need for products with a national scope. In essence, the marketing powers in the early days of the Internet functioned as national distributors and these national distributors wanted national products that would play to their national audience. Three products that were in demand, but which no one was quite sure how to produce, were mapping, routing (navigation) and business listings integrated with mapping and routing.

I doubt many people today realize that until the rise of the Internet there was not a compelling need for a national business directory or an integrated, national, yellow page type of system. It was not until somebody decided they would like to provide a yellow page type of service online that they realized a comprehensive directory of businesses across the United States simply did not exist. Yep, those local yellow page directories worked just fine, because they were used by local audiences. When you needed to know something about a service in another town or in another state, you headed to the Library, whose librarians conveniently collected every YP book they could get their hands on. Sounds antiquated doesn’t it? But the point that I am making is that national products using maps, navigation and yellow pages and business directories had their births in the 90s when a new distribution channel made it possible to advertise a class of businesses that could not afford national coverage on television or radio.

There were two leading choices to solve this supply problem. First, you could try to integrate disparate sources into a seamless national database. Alternatively, you could simply find a provider who builds national databases and license their product. Those who tried the blend approach wound up in a world of headaches. Yes, could always find ways to conflate data, but you could rarely find any satisfaction while trying to understand how every source you found could categorize simple things like road function classes or business names in so many different ways. Needless to say, service suppliers decided that they did not want to try to integrate disparate data. Instead, they sought national providers who could give them a database that was advertised as consistent and ubiquitous and let them get on with the job of serving data and making money.

In essence, as distribution changed and markets for new services emerged, national players trumped local players. However, were national players able to provide better quality data?

I am sure that the providers of navigable map databases and navigation services regard each and every street as important to them and that they work as hard as humanly possible to produce highly accurate and up-to-date maps everywhere. Unfortunately, their model does not scale uniformly because they do not have a large enough field staff to collect accurate data on a timely basis in all of the localities where they need to do so. Instead, these companies suffer from the problem of contention for attention in regards to data collection. They must spread their field research teams over large areas and this often results in their missing significant changes in streets, roads, highways, other map data and attributes.

In order to compensate for the lack of adequate field staff and resources, the big three (NAVTEQ, Tele Atlas and Google) spend a lot of time data mining and conflating data originally created for other purposes. While conflation can be a very useful technique, it is often the tool of the data hungry and your hunger always determines what you eat, not what you should eat. Let us take up the rest of the story, including the three-legged stool of map compilation next time, with an eye to why a local approach or the distributed local approach (OSM) might be the best.

Better Maps Through Local Thinking

July 9th, 2010 by MDob

I apologize for the delay in posts. A couple of months ago I had to move Exploring Local to a new platform and the support of the service provider has been less than stellar. In fact, I am not sure this blog will publish, since I tried it yesterday and it broke the system. I hope it works this time.
Although I have PhD in Geography, my graduate work was focused on cartography. For many years, I thought I knew something about maps, map databases, GIS, navigation and a host of related topics. Indeed, I was so sure of myself that I taught undergraduate and graduate level courses at the State University of New York at Albany espousing my views on maps and mapping. Having grown even more certain that what I had learned about maps was true, I accepted a position at Rand McNally & Company and was their Chief Cartographer for thirteen years. Eventually, I decided to go solo and opened TeleMapics, my consultancy. I have spent most of the last decade working with clients who are interested in using spatial data for maps, navigation, LBS and a variety of practical applications.

What I learned about map databases during my career is that making them is a data driven process. Without accurate data, your application cannot communicate the information that will resolve the spatial question that had caused the user to refer to your database in the first place. While a large number of top-down processes are applied to make map data useful, such as simplification, symbolization, classification and other aspects of a process that cartographers call map generalization, all of these manipulations, in the end, are constrained by the quality of map data.

From my perspective, creating maps and map databases are examples of a data driven or a bottom-up process. From a logical point of view, if the data do not allow an inference, it would be incorrect to assume one. For instance the road overlay on the Google map of Providence, does not match their imagery. At some point in his travels the driver must enter into an ASM (Arnold Schwarzenegger Maneuver), accelerating the car to 162.615 miles per hour to leap the intervening quarter of mile where the imagery shows no connecting road.

Maps and reality can vary - trust reality.

Yep, I know, I am being too harsh. After all, somebody is going to write the mother of all algorithms that will pick, pack, prep, collect, coordinate, conform, mish, mash and manipulate all of these diverse data sources into a cohesive, spatially accurate map database. Sorry people, but it’s not going to happen. There are fundamental data collection problems in the world of spatial data that still are not resolved. For example, where can you find a definitive, authoritative, up-to-date, comprehensive database of all occupied residences in the United States? While the US Bureau of the Census might have one, they can’t give it to you due to Title 13 restrictions on privacy. Hmmm. Is there an alternative? If you suggested the USPS, you need to do some homework. Do you know that even if you could find this database publicly available (and you cannot), you could not find the map data on which you could display all of the streets for all of the addresses contained in the data.

Apparently, it doesn’t seem to bother consumers that the map databases provided by the major map database producers are incomplete, out of date and otherwise erroneous. Maybe if you just keep slathering on the eye-candy everyone will forget that you can’t use these maps to get from here to there and sometimes you can’t even find “here”.

Conversely, map producers know that map database creation and updating is a game of Whack-A-Mole that they can never win. Even utilizing crowdsourcing, data collection vans instrumented with inertial systems, lidar and who knows what else, they have been unable to keep their databases accurate or up-to-date in a uniform and comprehensive manner. In fact, there may not be enough money in the world to create an up-to-date, accurate and comprehensive street map of, say, the United States. Of course, this raise the question of what accuracy and comprehensiveness actually mean in the world of mapping. From a practical perspective the answer is unappealing, but since you asked, the “commercial” answer is, “What’s good enough.”

Really? Yep. Commercial mapmakers don’t actually know how good or how bad their data are at any point in time, because they have no effective way to test their completed database. Yes, they have quality control and quality assurance procedures and yes, they may be ISO certified, but that does not stop them from distributing data that are clearly erroneous.

It is sad that modern routing engines and the databases they use are prime examples of this contention. I have read numerous articles where the reporter has indicated that they previously used Google for their mapping and routing needs, but stopped doing so when Google decided to become the poster child for bad map-making practices. However, I am sure that all of these folks would tell you that they are not satisfied with the mapping and routing service they presently use, but that this is the one that gets them where they need to go more often than the others they have used.

In fact, the notion of the incompetence of the routes that you get from your online or mobile provider has become a glamorous component of the “war stories” most travelers unroll during an unexpected flight delay. Have you heard this one – “So it told me to take a right out of the driveway, took me through 23 other maneuvers (for some reason it’s never an even number) and eventually navigated me to a place within a block of where I started, although the route covered two miles.” Been there, heard that.

Well, then fixing these errors must be an important task and a priority issue for the companies involved. So, what exotic technologies do these companies use to find and fix the data that are erroneous? The embarrassing truth is that the best indicator of update priorities is customers who tell them what’s wrong with the data and these companies don’t even have to ask. What a great business model, huh?

Conversely, If no one complains about the map data quality, there is little chance that bad data gets fixed. It is sort of like the map database version of “Don’t Ask, Don’t Tell”. Common sources of error correction for customer input includes email, phone calls, customer sales calls and the more modern correction systems like the online map error reporting websites of NAVTEQ or Tele Atlas and the crowd-sourced error correction applications like TomTom’s MapShare. Yep, no knowledgeable humans on the map database vendor side of the equation – only a simple “Just the facts, Ma’am”, Jack Webb type of interrogation.

But wait, let’s get back to that “What’s good enough” issue. What does that mean? Well, it means that the map data are “good enough” to satisfy the needs of the companies willing to license the data. Yes, the clients will complain about errors that are found by their internal product development teams or convey the errors that are sent to them by their customers, but, by and large, the customers of the leading map database providers are a captive audience. If you need a national database to assist in creating your spatially based services, “who ya gonna call,” other than NAVTEQ, Tele Atlas or someone who packages their data?

How can this be?

In the big leagues, map updating is carried out as a two-tier process. Customer complaints drive topical updating where egregious errors are prioritized, researched and corrected. In addition, mapping companies systematically review their entire database on a more or less set schedule, but some areas of the database may not be “touched” for years (if they are rural, remote and unpopulated) while other major urban areas may receive attention that is more frequent.

The word “review” is the fly in the ointment here. The reality is that map databases are updated by comparing them to sources (including field observation) thought to be more current or more authoritative than what you already have in your database. If found to be more current, reliable or accurate than what is in the database, the new data (depending on the type and authority of the source) are either added to the database or used to focus further research for updating. If the sources are not better than what you have, they are tossed. When you have collected what you believe to be the best data for a specific location, you are not going to look at this area again until someone complains, or you discover what may be a more up-to-data or authoritative source during your systematic update process. It is for this reason that map databases contain numerous errors waiting to be discovered by unsuspecting users.

The most valid source for gathering street map data is reality or some method of memorializing its complete details, at least the ones of relevance to mapping (as Google does with its Street View service). Compiling from existing maps or spatial databases means that you have bought into the method induced compilation errors inherent in the procedures used by whoever produced the data you are examining. Unfortunately, you are usually not going to discover the competency of the data or the data gatherers from metadata. So, what’s a body to do?

Crowdsourcing is one response. Although I am a great proponent of crowd sourcing and believe it to be one of the most promising methods of creating up-to-date maps, I am not sure that it will produce a reliable, accurate, comprehensive seamless street level database, over an extent as large as, say, the United States, or maybe even a small region such as the Delmarva Peninsula.

While the OSM product might be of sufficient quality in a number of cities, it is less likely to be of uniform quality across large physical extents with variable population densities. In addition, I suspect that it might not be of very good quality in areas of low income, high crime and other socioeconomic attributes that would convince many data gatherers to avoid these locations. Yes, OSM does use public data sources when available, but here again, you face the issue of adopting potentially erroneous procedures that plagued the original data compilation process.

My greatest concern about active crowdsourcing (active participation – not probes which I regard as passive participation) is that I am not sure it is sustainable over long periods. I realize that its present supporters might be willing to dedicate their time to this effort, but what happens in five or ten years? Will willing replacement data gatherers be found or will OSM become a collection of floating point data sources? Alternatively, might OSM collapse from neglect? Or, might OSM become a series of local data collection tribes. Hmmm. NAVTEQ and Tele Atlas have been around for approximately twenty-five years (since the mid-1980s); will we be able to say the same thing of OSM in 2030?

I have to admit a bias here. I like the concept of crowdsourcing, but think that in the long run it will prove inferior to the ability of for profit firms to sustain quality driven, map database updating using traditional field, research and crowdsourcing techniques (as Google does today, but inefficiently). On the other hand, I am not sure that international map database producers like NAVTEQ and TeleAtlas can compete in local markets with local companies or for-profit groups that are prepared to compile a map based on local sources.

Let’s talk about how that may happen next time. In order to do so , we will need to discuss why many important markets for map data may be, inherently, local.

I will be at the ESRI UC next week and will let you know if I see anything interesting.

Just For Fun!

June 22nd, 2010 by MDob

Those of you who are in a serious mood should skip today’s blog. I just can’t seem to get my motor started this week and have been looking for some inspiration. Unfortunately, I found it in the wrong place. I blame Father’s Day!

On Father’s Day, I received two t-shirts. Now, since I spend most of my life dressed in t-shirts and shorts, this was a good choice for a present. However, my grandbabies decided that I needed an “Old Guys Rule” logo on one of the shirts. Even worse, it has a guy with a white beard and my sun hat loafing in a hammock (no, I don’t own or use one). “Old Guy”, when did that happen?

The second T-shirt was from one of my sons, who once worked for MapInfo, but obviously does not read this blog. He gave me a Google Maps T-shirt, with a Google map marker on it followed by the words “I am here”. Well, where else would I be? Of course, I will wear both t-shirts with great pride!

Now for something completely silly, but of vital importance.

I discovered theoatmeal.com earlier this week and have been laughing ever since. While visiting theoatmeal, I discovered a link to a blog at mingle2 and created the following piece after having been spurred on by reading “How to tell if you cat is plotting to kill you.”

Generally, I am not one for conspiracy theories, although I would like to know the real story of the undercooked fifteen million pounds of SpaghettiO’s. My buddy Bob, who knows about everything has told me that the SpaghettiO’s reportedly contained alien life forms who were planning to invade and take over Wal-mart’s operations.

However, on a more serious note, the evidence is mounting that your Online Map Provider is planning to kill you, or at least set you up for an assasination attempt. The vendetta may be the result of your having sent in too many map corrections, supplying false map corrections (as a test, of course), or just criticizing their maps and routes. Guess these three reasons pretty much capture the entire population of the world and that is why this story is so important.

Yeah, yeah, I know what you’re thinking, but this is serious stuff. Everyday, the press seems to be full of ample evidence that the companies providing online routes and route guidance are actually not in the mapping or the navigation business. Instead, they are the advance agents of a ruthless alien invasion dedicated to wiping out humanity. Yep, it is likely the same aliens behind the SpaghettiO’s covert invasion force (if hiding your invasion forces in cans of SpaghettiO’s isn’t being covert, I don’t know what qualifies). Oh, so you doubt the integrity of this story? Well, consider this (and ask yourself how many times these things have happened to you already…).

the old e911 delaying trick

1. The address you entered into your preferred mapping application no longer geocodes, even though you are sure it did the last time you used it.

Analysis: In reality, this is a poorly disguised attempt by your map and route provider to delay the 911 services from rescuing you after your map provider has made the “hit” on you. An alternative to this common ruse is the old ploy of geocoding the location of your house a block north,south, east or west of where it actually is located, or, sometimes at the wrong end of the block. Oh, so you’ve never run into that situation? Really!

2. The streets you are interested in visiting are not on the map, even though they have been on other maps of the area for the last twenty years. Yep, even on those old printed maps.

Analysis: This tactic is the result of resource limitations. Yes, your map provider simply cannot afford to put snipers everywhere.

3. You keep receiving the infamous “You can’t get there from here” message or the “We can’t find your destination.”

Analysis: Oh, your map provider can find the location and, in fact, you will be able to get a route to the location later the same day, but not until they finalize the trap they are setting for you along the route they will provide. Now you know why you navigator insists you turn around to get back on route rather than rerouting you.

Historic route, maybe even scenic route, from typical online map provider

4. When you select “historic” as the routing option, your map provider takes you past locations that would be memorable only to a Mafia hit man.

Analysis: If your skin starts to fall off during the drive, seek an alternate route to your destination.

typical example of erroneous route guidance

5. The route guidance (routing directions) provided takes you the wrong way down one-way streets. This hasn’t happened to you yet? Really!

Analysis: You are the one who should know the terms of use for these online mapping and routing services. In the case of Google, for example, the license indicates “… (a) Map data, traffic, directions, and related Content are provided for planning purposes only. You may find that weather conditions, construction projects, closures, or other events may cause road conditions or directions to differ from the map results. You should exercise judgment in your use of this Content.” What you don’t know is that the planning purpose mentioned in the Terms of Use is actually “We are planning to kill you!” Don’t know what the term “other events” means? How about assasination. Really!

The amazing, disappearing map tile

6. Your map provider renders every tile in the area of interest, except the one you are currently navigating. (Danger, Will Robinson, they are waiting for you just around the corner).

Analysis: When you see the blank tile on your screen, turn around and head for safety. If you are on your phone, turn it off or you will see the blank tile surrounding you everywhere you go on the map. But you already knew that, didn’t you? Really!

7. When you select walking routes, the route provided invariably take you through the most dangerous neighborhoods in each of the cities you visit, even if these streets and neighborhoods are not on the route to your destination. Trick – show the route to the doorman of you hotel. When he howls in laughter, discard the route.

Analysis: sometimes, they even take you on streets that are poorly illuminated, have high traffic and actually have no sidewalks. Oh, wait, that was in poor taste, since it appears to have actually happened.

8. The turn-by-turn directions are provided a block or two too late to execute the required maneuver, so you execute a parking brake-assisted U-turn, forgetting that the result of this maneuver will have you traveling the wrong way on a one-way street.

Analysis: bing, bang, boom, they win again! Really!

9. All of a sudden, streets on maps start to look like the people who are following you (I am not making this up. See the following illustration.)

I know I've seen this map before.

Analysis: well, you were warned. Moreover, don’t try to look me in the eye and say that you don’t know or work with someone that looks like the map above. Yeah, really!

Okay, Okay, I have had my fun and will come back with something more interesting next time. (My apologies to Seth Meyers and Amy Poehler of Saturday Night Live. Really! The same apologies to the talented artists at theoatmeal and the Mingle2 blog.)

Got Some Whuffie For Your Favorite Mapping Service?

June 17th, 2010 by MDob

Lately, I’ve been doing a lot of reading about social networking and now know that the good karma you accumulate for making positive contributions to your network is called “whuffie” (don’t blame me, I only report the news). If you want to know more about whuffie, you can find the book at Amazon. According to Tara Hunt, the book’s author, “what it comes down to, in this Web 2.0 world, is that there really are only three ways to build a business and make money online: porn, luck and whuffie.” Tara continues by indicating that you can generate whuffie in a variety of ways, but one of the best is by creating amazing customer experiences that involve great products surrounded by satisfying user experiences.

From a practical perspective, this is what makes Apple products so great. The iPhone, for example, is a powerful computer, but those who use the device never are exposed to “computerese” and rarely exposed to errors. They just tap their device and it works. In fact, this ease of use is the reason behind the unexpected success of the iPad. It’s a bigger iPhone-like device that just works. It doesn’t appear to be a computer. It just turns on and you can do stuff without waiting for it to boot up, without having to sign-in, close the annoying notice from Word that normal.something has written a new version of itself or that you can’t access a website because “You may not be connected to the Internet.” Sorry Microsoft, I am connected to the Internet, it’s your operating system that is not connected to Web 2.0.

It dawned on my as I read Tara Hunt’s ‘whuffie” book that the notion of “amazing customer experiences” is exactly what is missing in the world of mapping and navigation. Going back to Tara’s quote above and applying it to map services, we don’t offer porn, our maps had better not be based on luck and providers of map services may not be capable of generating whuffie from their communities.

This morning, for example, I fired up my iPhone and took a look at the Google Mobile application. I selected “Maps” and the app asked to use my current location. I agreed, presuming that the use of GPS based location might avoid any uncertainty about where I was at the moment.

Well, I was sitting in my home after an early morning walk eating breakfast and avoiding real work for a few more minutes. I was amused when the first map location Google showed for me was about two miles east of my actual location. Abruptly, I appeared to move a mile south to the Shops at Mission Viejo and then, according to Google, I jumped to the middle of the I-5 Freeway where my location symbol sat for about thirty seconds before moving to a position that matched my actual location. While the movie “Jumper” was modeled on my ability to teleport to new locations, I was not using that particular super power while viewing my iPhone. No whuffie for Google Mobile.

And no whufflie for NAVTEQ, since the company still has not managed to fix the error in Providence, Rhode island on their website. Instead, they continue to refuse to use their own latest database release (must be a licensing issue, maybe they haven’t paid their bill) preferring to use a 2010 copyright on data that doesn’t come from their 2010 database release. Of course, since NOKIA appears to be in freefall after their financial warning, it may not be possible for NAVTEQ to fix the error in the foreseeable future. Maybe they will be sent to the whuffie penalty box.

While we are on the topic of copyrights, I was amused last month (that’s right, in May) when Rand McNally sent me an email indicating that I now could buy a copy of the Rand McNally 2011 Road Atlas. One the one hand, you think the company might be able to afford the send their ex-Chief Cartographer a free copy, but that’s just another piece of embarrassing self-promotion, so let’s move on (no whuffie for me).

On the other hand, how could you publish a road atlas in May of 2010 and label it 2011? Doesn’t that stretch the limits of credibility? When I worked at Rand, we began printing the Road Atlas for the next year in late July and the production run was so large that the atlas printed 24/7 for over a month on high-speed presses just to create the initial inventory necessary to meet the distribution requirements for the product release in September and October.

I doubt that many people are buying print atlases anymore, so the production run is likely significantly smaller than a decade ago. If that’s the case why move the production date back? I guess the answer is moolah ($) based a marketing strategy that hopes to take advantage of an economic climate where more people will be staying closer to home and reverting to driving vacations, rather than “flying” vacations. But still, don’t you think that the Wal-Mart shoppers are going to take a look at the cover and wonder how this atlas can include road changes for 2011, seven months ahead of the calendar? No whuffie from them either.

Every time I open the news, I find another pundit who has realized that Google Maps is an unreasonably, unreliable product causing them to switch to some alternative map provider after describing the numerous routes that were scrambled on Google. The last interesting one I saw was in Albuquerque where Google thinks the local air force base is the local commercial airport. Even after having been contacted by official authorities and changing to the correct location, it reverted to using the air force base as the airport a few weeks later. Double no whuffie for Google!

The problem with no whuffie for mapping is that the situation is bound to get worse. I realize that Google is innovating towards a solution to its mapping problems and feel it is likely that they will improve in the future. Similarly, NAVTEQ knows how to compile data and once it finds a way into using crowd-sourced data, it should be able to advantage itself and produce product with enhanced accuracy. TeleAtlas has benefitted from its acquisition by TomTom through the advantage of the huge number of people contributing map changes and probe data through MapShare. OSM, also, continues to improve it quality and coverage. However, the reality is that no map database provider is capable today of creating a street-level database that exceeds or even matches the expectations of their customers, at least the rational ones.

Who is the “Apple” of the mapping world? No whuffie for anybody! The problem of concern to me is that the kinds of mapping we are seeing on the Web today are based on simple concepts and, even then, nobody seems to be able to figure out how to do them right.

The difficulty I have is that Google, Microsoft, Apple (yes Apple) and others are about to take the next step in mapping. Yep, instead of navigation, place-finders, and map pin types of applications, these titans of industry are going to move into real mapping, GIS and analytical uses of spatial data. I have just two questions. Where will the knowledge base for all of this development come from? Who is authoritative? No whuffie for us – mapping as a science is doomed, although mapping as entertainment appears to have a strong future.

Well, enough of this grousing. Next time let’s look at the notion that “information is tribal, while map database builders aspire to be global”. Is there a way to take advantage of this tension?

Google and Smash, Bang, Boom

June 3rd, 2010 by MDob

By now, most of you have read about Google Maps providing walking directions that may have contributed to the user of these directions being hit by a car as she attempted to cross State Route 224 in Park City, Utah. I am neither a lawyer, nor do I play one on TV, but here is my take on the issues.

The best description of the walking directions fiasco can be found in two articles by Danny Sullivan at Search Engine Land, who spoke to the attorney representing the woman struck by the car.

The facts, claimed by the plaintiff, are that she used her BlackBerry to access Google Maps and requested ‘walking directions” between two locations in Park City Utah. Loren Rosenberg traversed the route at six in the morning, when it was dark, and she could not see across the road to determine if the sidewalk she expected to be directed to was actually present or not. While crossing the road she was struck by a car (whose driver is also being sued). Further, it is claimed that warning text (describing the accuracy of the directions) that is now provided on Google’s Website was not presented on the mobile version of the website when the accident victim requested the walking directions in January of 2009.

Of course, with the exception of Danny Sullivan (and his first blog was quite negative about the woman’s actions), the web has been afire with comments. Most of these comments have been about dumb Americans, dumb American drivers, dumb people using the Internet, people lacking common sense using online maps, people lacking common sense about navigation systems and a variety of epithets that, in general, seem to take joy in demeaning the intellectual capabilities of the accident victim. Curiously, many of the comments appear intended to defend the greater glory of Google Maps (even though if Google had examined its own Street View footage, it might have ruled out the route as a reasonable one).

Further, there have been a number of comments playing this tune “It’s a beta…” Oh please! Walking directions have been a beta since July 2008 on the desktop and November 2008 on Mobile. Two years later and the service is still a “beta”?

Well, when will it graduate? Is it the software or the map data that’s still the “beta”, or both? When might we expect a final product? Alternatively, is it possible that Google is attempting to avoid liability by classifying its navigation service as “beta”? Assuredly, all Americans who use online services and the majority of the citizens of other countries of the world using the same services understand what the term “beta” means, as well as possessing complete familiarity with software life cycles. Not a chance!

Some people are just humans, trying to get through their day and using the Internet to help them do so. To the ever-popular “Joe Six-pack”, the Internet and navigation services are like a refrigerator. He uses a refrigerator because it preserves keeps his beer cold until he can drink it. He may not be sure how the refrigerator works, but he has the reasonable expectation that its common name defines what it does. Sort of like “walking directions” – which, of course, differ from something named, say – “potentially dangerous walking directions.”

Those of you who have read this blog for a while know that my background is maps and mapping and that I have had considerable experience in the map business, covering areas of creation, marketing, distribution and liability, which lead me to my next point. Regardless of how you feel about Google or about mapping and routing services, or the general state of map use, you should stop and think about the legal system under which this case and future cases like it will be prosecuted.

First, if this case is tried in a court of law (a state court, likely, but I doubt Google will let the issue go to trial), you should note that the American jurisprudence system and American juries generally lean in the favor of protecting the consumer and that may be a reasonable and socially beneficial goal. Indeed, a group of jurists decided the coffee a 79-year-old woman ordered at a McDonald’s drive-thru was too hot, after she put the cup between her knees, tried to open it, was scalded and subsequently hospitalized for two weeks, when the coffee spilled. The original trial award for the incident was $2.9 million, but later the case was settled for substantially less. (And how many of us still have scars on our tongue after eating a molten hot McDonald’s Apple Pie Tart, baked by a sun lamp to a moderate 3200 degrees Fahrenheit?)

Perhaps most importantly, the lawyer for the plaintiff will argue that the user of Google’s map services has a reasonable right to assume that Google has endeavored to produce a service that can be used for purposes of pedestrian navigation and that the product is safe to use. What, it’s not safe? What, the data has not been tested? What, the company has made assumptions about the integrity of turn-by-turn direction that have not been vetted? What, the company had data in its possession, collected by its own industrious endeavors (Street View), that would have rectified inaccuracies in the route, but the company did not refer to these data when evaluating the safety of its own recommendations?

On the other hand, think of it this way, if you would prefer, with Spencer Tracy playing the plaintiff’s attorney: “Ladies and gentlemen of the jury, my client Loren Rosenberg, had an early morning interview across town in Park City, Utah. Her car had broken down and, desperate for a job, she had no alternative but to walk to the appointment, a considerable distance away. Ms. Rosenberg, a mother of 4 young children, did not know the path to her destination and used Google Maps, an application provided on her BlackBerry, to assist her in this journey.”

“Entering her location and the address of her destination resulted in Google’s navigation service providing her with “walking directions” between her current location, at the time, and her intended destination. Due the distance she was away from the destination, according to Google, she needed to leave early to be navigate the path and be on time for the appointment. It was still dark when she began her journey at six in the morning on that cold and snowy day in January 2009. She followed the turn-by-turn directions in the sequence and manner provided by Google, believing that Google was directing her to the safety of a sidewalk on the opposite side of Deer Valley Drive, along which she could continue her journey.

My client was struck by a car and grievously injured while following an instruction in the directions Google provided that required her to cross the road and walk along its other side. Unfortunately, the intersection was not illuminated by street lamp and the written instructions did not indicate that the Deer Valley Drive, a peaceful sounding name, was actually a state highway, a fact that my client could not ascertain in the dark early in the morning as she approached what appeared, to her, to be a lightly traveled street.”

The story will only get better from here. Trust me.

Now Google, in preparing to defend itself will hire experts to wax eloquently about maps, map use, map generalization, turn-by-turn-directions, projections, navigation, disclaimers and a host of technical issues that to the readers of this blog might seem like common sense. However, 99.99 percent of Americans do not read this blog and 99 percent of Americans do not know what you do about mapping, navigation and map databases. I bet your friends eyes glaze over when you start talking shop. My friends have learned that the least mention of something spatial can lead to a 72-hour colloquium and want nothing to do with it. Juries decide cases on what seems reasonable to them and what is reasonable to them is that things that are provided for a specific use “just ought to work.”

I know, some of you are going to say, “…but navigation is free service from Google and you get what you pay for.” Sorry, but maps and directions are a big part of Google’s local advertising strategy and Google makes a significant profit on this and other types of online advertising. Walking down the street is free, but if I slip on business card that you carelessly dropped and injure myself seriously, guess who is going to court?

Litigation and consumer rights will become a significant part of the landscape of online and mobile mapping, navigation systems and Location Based Services. My fear is that cases such as these could stifle innovation in the industry and may serve to penalize smaller firms much more so than larger firms. Welcome to the big leagues.

So, what to do (disclaimer – I am not a lawyer, see a real one for actionable advice)

If you provide a product, talk to a lawyer about your business, risks and expected and potential use-scenarios for your data, platform, applications, and services. Seek capable legal advice on how to best protect and defend your business and your employees.

If you own a small company with online products, be sure that your “terms of use” are prominently displayed and that they provide the suitable warnings and disclaimers for the use of a product or service of the type you provide. Make sure a competent lawyer crafts these terms.

Create a functional and durable corporate memory (written). In an issue that I was involved in recently, there was a question of when an action was originally taken by an Internet firm. The issue revolved around when particular software functionality was first provided and when it was later altered. As in most start-ups, no one had a clue about the timing of the company’s software release dates, other than the day they launched their website and maybe their first app. All subsequent changes to the code and functionality disappeared when the tapes were wiped as part of their backup recovery of storage media.

As a side note, this is why it is so difficult to create a valid history of the Internet. Most of us were so happy to finish something that we pushed it to “live” and then started revising it with all the new features we could not get to the last time. Almost no one bothered to write down when things happened; we considered the stuff that was live as old and uninteresting. Anyway, we were working on the good stuff.

What might happen in the Google case?

Many of things could happen, but it is often cheaper to settle legal issues than to litigate them. Defending an injury case could, for example, run over a million dollars at a minimum and, for this reason, settlement is often a preferred outcome. In addition, a complex court case will require the time of many of your most talented technical staff, who could be creating new applications and this is another pressure that leads to settlement. Finally, there is the common problem that the only person who really knows how the functionality works either just left your employment or is that “special” member of your staff (don’t feign ignorance)that you don’t want talking to other humans.

If Google choosed to settle, the settlement will be confidential and no one will actually know the result, other than Google and the plaintiff, who will be bound by a mutual confidentiality pact. If Google chooses to litigate and loses, it will likely then offer a better settlement than the court offered and convince the other side to vacate the case and the judgment, so that it will be as if the case never happened. Then we can start this all over again with someone else, but without a precedent.

See how smart reading the blog has made you? Oh, I can “feel” the comments already. It’s going to be uncomfortable – kinda like eating one of those old McDonald’s Apple Pies I mentioned earlier.

What Are We Looking For In There? Is It News About Nokia And Yahoo?

May 27th, 2010 by MDob

I have been spending a lot of time in my office working on various client requests for TeleMapics and other business interests that I service. I have become something of a shut-in recently as I continue trying to get ahead of the workload, but without great success. Yesterday, I broke off for a lunch at Baja Fish Tacos with a business associate.

You know, Orange County can really be beautiful and the weather is often fabulous. Yesterday was one of those perfect days. Yet, as I drove along a beautiful stretch of road, almost everyone I saw was ignoring reality and looking at the screens of their cell phones, yep, even the drivers. People on the street were walking while staring at screens. As I drove into the parking lot, I had to be more cautious than usual, as most pedestrians were going to or from their cars staring into those tiny screens. Even my buddy was sitting in front of the restaurant, staring in to his screen. What are we looking for in there?

Obviously, this focus on the small screen has significance for evolution and the development of humped backs, increases in the population of beady-eyed people, and smaller, longer fingers, as well as the possibility of 360 degrees of movement in our thumb knuckle joints. But I don’t care about that. Inquiring minds are asking, “What are we looking for in there?”

Recently, when I was killing some time between appointments, I peered into the screen of my mobile and saw this article, “Yahoo Looking To Blow AOL’s Patch Out Of The Water”. Good for them. Who knew? Who cares? Have some patience; AOL will blow itself out of the water, just as it has done so many times before. Do you know how you spell AOL? Yep, that’s right “i-r-r-e-l-e-v-a-n-t.”

Next, I saw an article titled “Yahoo buys Koprol”. My initial reaction was “Save us, cut the electric grid now and dismantle the wireless towers.” Do you know how you spell Yahoo? Yep, that’s right “c-o-u-l-d-b-e-i-r-r-e-l-e-v-a-n-t-s-o-o-n.” Is this really the stuff we are looking to find in our phones? Or is our interest in what our recently found 3392 best friends have just posted on Facebook about their day? I’m not sure.

When I next stared into that small screen, I found out that Nokia and Yahoo seem to think we are looking for access to email, maps, messaging and local information. Hmm. Could this Nokia/Yahoo thing be important? And, in retrospect, could the two announcements above be important?

I thought that a Reuters report on the deal between these two titans seemed to have it right in that it downplayed the significance of the worldwide, strategic alliance between the companies. I reasoned that there has to be more to this partnership than meeting the consumer needs for mundane things like maps and email, but Carol Bartz, CEO of Yahoo, quashed my intuition by indicating that the relationship with Nokia is not an advertising-based partnership.

In addition, Bartz stated, “Yahoo lost its focus on maps a couple of years ago” and seemed to be using this as the motivation for switching to OVI Maps. I’ve got some bad news for Carol. Yahoo Maps may be better designed and more useable than the OVI maps that will replace them. The functionality in OVI maps is buggy (although I do like their 3D view), the service is slow and the maps appear even more out of date than the Yahoo maps, as they show a 2009 copyright (both use NAVTEQ data). In addition, the traffic warnings shown on the OVI maps are not as current as the traffic conditions shown for the same areas on the NAVTEQ website (same day, same time). (The combination of Nokia’s MetaCarta and Yahoo’s WhereOnEarth properties may be quite interesting – but not directly related to my interests here, so we will move on.)

Of course, the problems with serving and functionality mentioned above can be fixed, but I am not sure that Nokia or NAVTEQ are the companies to make these fixes, since the maps on the websites of both companies do not load as fast as the maps on Google, Yahoo, Microsoft, MapQuest or even Yahoo for that matter. Next, as I noted previously, the maps on OVI Maps and NAVTEQ’s website are not derived from NAVTEQ’s latest database release. Maybe they should take lessons from MapQuest who appears to be using NAVTEQ’s latest data!

On the other hand, perhaps Nokia and NAVTEQ need some deCarta? Maybe they need to purchase deCarta?

So, I think that we should conclude that “better” mapping is not the issue that sealed the deal. Free maps for Yahoo and free email access of Nokia users, now that might be more persuasive, but no financial information was released about the cross-licensing of maps, navigation, messaging or email functionality.

In order to appreciate this deal, I think you need to look under the covers, so I did a little research. During the press conference, the following image was shown and it contains some compelling information.

What each partner brings to the deal

(Click here to download a larger PDF version of this image.)

Although there may be some side-benefits from the deal to help Nokia with the unfamiliarity of the OVI brand in North America and with Nokia’s abysmal position in the North American phone market, I think this deal needs to be evaluated by its significance outside of North America and Western Europe.

It is my opinion that “infrastructure” may be an important reason behind the deal. Many countries around the world lack a well-developed wireline infrastructure either for their telephone systems or for their Internet services. In numerous “developing countries”, cellular phones are the device of choice for accessing the Internet and using email. In addition, it is my belief that, in these countries the focus of the use of messaging, email, Internet and maps is more likely to be local (as opposed to regional or national) than in the more “developed” economies. As a consequence, the users may gravitate to the platform that will advantaged them by providing access to quality local information (see, those first two news items mentioned at the start of this blog actually may be key to the success of this deal).

In other words, the Nokia/Yahoo deal is an example of the paradox that as the economies of the world become interlinked and globalized, societies seem to be becoming more “tribal” and tribal equates with local. The advent of Local-Social networking is a prime example of these trends and reflects the obvious interest that all of us have in knowing “what’s around me.”

It appears Yahoo could become a valid alternative to Google. Before this deal, Yahoo lacked the DISTRIBUTION to get its product to the masses. Similarly, while Nokia had distribution in the parts of the world coveted by Yahoo, it did not have an Internet presence that the masses would find relevant to their interests.

Perhaps the Nokia/Yahoo deal will work out to be significant. However, to “make it so” Nokia will have to show more flexibility and less “Finland-vision” than it appears to have been able to muster in the past. This deal is really about the balkanization of information and global publishing. While it is good to have companies like Reuters and AP, they are not where I turn when I want to find news about Laguna Hills or Orange country. I think the rest of the world will vote the same way and now Nokia and Yahoo may have forged a strategy that give them an opportunity to compete with Google around the world by providing local information or relevance to local populations.

Now for the real, but unpublished, news in the deal

As a side note, I was slightly surprised that it was OVI Maps that was mentioned in the deal and not NAVTEQ. Is Navteq on its way to being absorbed by the Borg of the north? Clearly, NAVTEQ is not a consumer-facing brand, so that may be the reason they are in the backseat on this one. However, they may be a significant beneficiary of the deal. What? How could that be?

Well, all of you (that’s all five of you) who use OVI Maps might be interested to know, at least according to my sources, that the 3.1 software license you signed with OVI sends probe data back to … Nokia and the amount of probe data may be on the verge of expanding exponentially with the Yahoo deal. Now OVI will be able to fix their traffic guidance and NAVTEQ will have another tool to use in its competition with Tele Atlas. How about that? Maybe that’s the kind of thing I am trying to find when I stare into that small screen.

For those of you in the U.S., I hope you have a terrific Memorial Day Weekend.

Maponics to Release Database of School Attendance Zone Boundaries

May 17th, 2010 by MDob

I had a conversation last week with Mark Friend, whose acquaintance I made quite some time ago when he was working for Vicinity Corporation (acquired by Microsoft). Later Mark and I were both employed at go2 Systems, an early entrant into the mobile LBS market. Mark was an executive in sales and I was the CTO and EVP of engineering for the company. I had lost track of Mark until he called me recently, telling me he was onboard at Maponics.

Maponics, with a staff of approximately 30 (up from 12 two-years ago) and sales divulged at “less than $10 million” is known as a provider of polygon data identifying neighborhoods. The neighborhood data created by Maponics are used by Google (search filtering – not mapping), Trulia, ReMax, Redfin, eNeighborhoods. infoUSA, Citysearch, Yellowbook, DexKnows, NAVTEQ, Twitter and others.

The neighborhood data is comprised of non-overlapping boundaries complimented by neighborhood “use type” (e.g. retirement community, commercial, industrial, subdivision, etc). While the neighborhood boundary business is an interesting one, Mark had called to introduce me to a new product that shows what an inventive, small business can do to open new markets.

Maponics’s new product is a spatial database containing school attendance zone boundaries. These are the areas around public schools that define the households that attend them. In addition to locally sourced public school attendance zone (SAZ) boundaries for covered metro areas, the product dataset includes nationwide coverage of school district boundaries, as well as private and public school locations and profiles. (Private school attendance zones are widespread, not nested within formal school district boundaries and discontinuous due to the elective nature of their attendance. Consequently, Maponics will provide the location of private schools, but not a representation of their attendance zones.

The first product release of the data will include granular school attendance zone-level coverage for over 20 percent of the K-12 U.S. student population and 100 percent at the school district level. Maponics is poised for significant expansion of its attendance zone coverage over the next several months, with at least 20 percent increases in student population coverage per quarter.

Maponics believes that its School Attendance Zone Boundaries dataset will become a “must have” in the real estate market, since the dataset allows parents thinking about relocating to determine which schools serve the areas surrounding houses they are considering for purchase. In addition, these data should be of interest to direct marketers who could use the database to target households by school attendance zone boundaries.

While the U.S. Census Bureau provides a School District Review Program that includes mapping, it is restricted to the “school district” and does not provide the granularity of the school-oriented attendance zone boundary data provided by Maponics. For this reason the company to believe that the SAZ data might be of use to government analysts and policy makers. In addition, Maponics speculates that there may be some play for these data in social networking applications. It is possible that the SAZ may represent a spatial representation of a “neighborhood” that is familiar to kids attending a specific school, while more commonly used definitions of neighborhood may not be on their mental map.

The procedures that Maponics uses to identify the school zones are laborious and involve significant manual work that, at present, may be the only way to capture SAZ information. The company uses “rooftop” geocoding to determine the location of the schools and works with contacts at individual school districts to determine the “attendance” boundaries of the schools included in the districts.

Mark told me that the source data are typified by a substantial change rate. My translation is that the tasks of capturing and maintaining the data are an ongoing and expensive obligation for the company and probably the reason behind the staged release of the product.

The initial release will cover 20% of the U.S. school aged population with additional 20% increments being added each quarter until the database is completed in early 2011. Mark noted that the company believes that the coverage of the databases will plateau between 90 and 95% due to the improbability of capturing all SAZ data everywhere or gaining the cooperation of all school districts. I queried Mark about the potential use of UGC for this effort and he indicated that it was something they were exploring, but had not yet concluded that it would be more effective than their current place-based data collection.

It is my thought that initially, not all school districts may want to cooperate with Maponics and this situation may provoke difficulties in reaching the saturation coverage required to make the product useful. However, if the introductory database is welcomed by the market (especially by policy makers and those in real estate), then school districts may proactively want their schools represented in the Maponics database.

I am sure that many of you reading about Maponics’ efforts in this area, must be scratching your head and thinking, “That’s a tough and expensive way to make money.” I agree. The one truism I have learned in my years of working with geographic data is that few customers understand or appreciate the value of spatial data or the cost to create a spatial database that is comprehensive, current and accurate. Fewer still understand the cost to maintain these data over time. Whether the future is good to Maponics will depend on whether or not the markets find value in leveraging the School Attendance Zone database into their applications.

My forecast is that the SAZ data from Maponics will be viewed as an attractive product by realtors and professionals involved in local marketing. Marrying the SAZ data with demographic information by census tract could help to create a compelling product (as well as one that would be fun to model).

I was somewhat concerned that the company was releasing a partial database as its initial entry into the market, even though it is their stated goal to complete the database within the next year. Perhaps their practical approach will win out. After all, who else is producing this data at this level of granularity?” Alternatively, should that question be, “Who else will be intent on producing this type of data once they see the Maponics press release?”

The SAZ database is being developed in a strategic partnership with GreatSchools http://www.greatschools.org/ : whose Great Schools ID will be included in the product. The companies will be making a further announcement regarding the full extent of the relationship within the next month.

Some portions of the material above were garnered during my discussion with Mark Friend, while other information was taken from the Maponics press release on the topic, which you can find here.

Four blogs in the last four days, phew. I need a rest. So do you. Take the rest of the week off. Tell your boss I suggested it.

NAVTEQ Had Providence Right in January

May 17th, 2010 by MDob

I have to eat “humble pie”, maybe “bumble” pie, today. I received an email this weekend indicating that NAVTEQ had actually fixed the I-195/I-95 interchange in Providence, Rhode Island in its first quarter 2010 release. The emailer told me that the database was released in January 2010. As you can see on the image below, the section of I-195 now being demolished is no longer represented in the NAVTEQ database and the correct reconfiguration of the highway is shown.

In its Janaury database release NAVTEQ had corrected Providence

I feel re-assured that NAVTEQ got it right and did so earlier than its competitors (TeleAtlas and Google), as I had assumed that its field operations would have caught this change early and was stumped that NAVTEQ appeared not to have made the correction. Apparently, the problem was that I did not have access to the contents of NAVTEQ’s latest database release and assumed (incorrectly) that what was being show on their corporate website was the best, most up-to-date data that they had. What a silly assumption! Why would a company want to put their best foot forward in an attempt to build a brand and become a customer facing business? Of course, NAVTEQ is in good company, since OVI Maps (Nokia) and Bing Maps are not yet using NAVTEQ’s most recent database release.

Perhaps more curious is the 2010 copyright date shown on the maps displayed on the NAVTEQ website, even though they are, apparently, using 2009 data. (I suppose we should not confuse the copyright date on the maps with the database release date – even if that is what a casual reader would do).

Maybe NAVTEQ should send that press release it issued on the need to have up-to-date maps to itself, Nokia and Microsoft? By the way, it appears that MapQuest (another NAVTEQ user) has ingested and compiled the NAVTEQ January update, as the geometry shown on its map of Providence appears identical to that shown in the NAVTEQ illustration above.

So, I need to give a “half-apology” to NAVTEQ. They got it right sooner than their competitors (Google and TeleAtlas). I feel bad for having beat on them, as this was based on my misunderstanding of the situation. However, I am not really feeling embarassed, since I still cannot figure out how anyone was supposed to know they resolved the problem, given that NAVTEQ did not (and does not) seem inclined to update their own routing application using their current data Maybe its data integration problems. Who knows?

And Something More

I took a closer look at Google Maps and they have figured out parts of the Providence problem, but not all of it, as you can see below. Maybe those 300 people in Kirkland will help solve this problem?

Let's take US 6 over the river to see Grandma.

While using OVI Maps I ran into a relatively unusual situation. When I searched for Rhode Island, the site responded with a message that it could not find Rhode Island

Where did Rhode Island go?

Or Providence, Rhode Island

No Rhode Island, no Providence, - seems logical

Or New York, New York.

Wait, has the East Coast disappeared?

At that point, I thought that maybe the application was only searching the map being displayed. Since the map on the screen was centered on my area, I entered Long Beach, which was shown on the map, but no luck – no Long Beach.

Online mapping, you just gotta love it.
