Who Makes MapQuest's Maps?

carpoolio writes "TechTV has an interesting story about the company that builds the mapping technology behind popular map services like Mapquest. The company, Navigation Technologies, is decidedly low-tech in its approach to making its maps: two people in a car drive around endlessly, inputting street information and landmarks into databases. Navtech's map databases are used in everything from Garmin GPS units to Alpine in-dash auto navigation systems. So next time you turn the wrong way down a one-way street, know that there are real people behind the controls."

    Apparently they have been looking for someone to do that since June.

      If only there were some sort of database that listed businesses and their addresses. Maybe we could even get phone numbers in there and put everything in a book ... a yellow book.

      Man, I want the job of those that just drive around with a GPS and record their track and what's out there. Especially on those nice long interstate hauls. Road trip!

      Seriously, this is both interesting and disappointing. I've been working, as a hobby, on a Palm-based GPS mapping program. The reason I'm not making much progress is because even when I'm done it's not going to be very useful without map data which is probably not available for free. I had hoped there was some hi-tech way to snag decent map data (at least the roads themselves) perhaps by digitally analyzing satellite photos, etc. But this is a low-tech approach which certainly suggests to me that there's no realistic way I could come up with nationwide road data for my Palm app.

      Oh well.

      Sure there is. What we need is an "open source" map. Have anyone who wants upload their GPS "track" data to a central site. A little data massaging will be able to use the average of plots to determine major roads/highways, and a few volunteers could add names and addressing schemes. Maybe the individual users could even supply those if they wanted, with another averaging system to determine the correct name of the street based on percentages...

      It could work. Would be a major, major project, though.

      Not to sound like a mean old man (well ok, I am a mean old man), but the hardest part of any such project would be sifting the bullshit out from the data.

      There's just too many ways for erroneous input to be included in such a vast database: Folks with an obnoxious "sense of humor," people with Things To Hide, grudge holders against various and sundry people, places, and things, government wombats with strange agendas, and never forget the Great Slimy Shoal of Lawyers who would seek to reorder things on behalf of Bob Knows Who, for Bob Knows What kind of reason. Pure random stupidity and mistakes cannot be ignored either.

      Odds of actually achieving a useful, properly updated, set of data aren't actually zero, but they're pretty damn close.

      We're already way ahead of you. I'm one of the developers at project OneMap. We are currently building and serving one of the largest, free repositories in the world, completly built on open standards. We serve content in the fashion of GML and store everything internally as XML. We've integrated quite a few sources so far, both from a few custom norwegian sources and from the US TigerLine-files.

      The main goal is to be able to update and review the content of our repository from within your own browser -- and we have the infrastructure to solve this. The biggest problem being that no-one has ever done anything like this in such a large scale, so we're kinda going along and feeling how the ground is all the way.

      Our gateway (for viewing the maps) are currently built on SVG and utilizes the open, formatted GML response. The source is going to be opened up and everything is going to be available for free, but currently we're having a few issues we would like to solve before going public. As always, this is a work in progress. I'm probably doing my MSc with just this topic (updating a map by many individuals) and a way of making sure that only REAL changes go into the repository.

    With a GPS receiver in many cell phones we need to figure out how we all can collaborate on creating maps. Here is a map I created with the data from my cell phone over the course of a couple of months. If everyone contributed instead of the data from a few people driving around we could pool the collective data and have great, open maps. This service is free until the end of the year, if everyone who can signed up and we pool the locations we would have a great map (not to mention traffic info.)

    My car has one of these things in it - the map systems runs of a data DVD rom in the boot (part of the CD changer assembly).

    As a result I have been driving in Boston for 3 months and can't find my way from end to end, unlike every other place I have lived in (I can drive around NYC, London, Cambridgeshire and Lancashire with no map no problem). I have no idea what connects to where at all.

    You need that period of getting lost all the time when you first move somewhere to really learn it, rely too much on GPS nav and you will never know the city properly :o(

    Cool for the odd weekend, but overreliance will cripple your direction sense. And worst of all, now I have lived here for so long I can't exactly switch it off and be late for everything - no excuse anymore.

    Now I'm stuck forever buying map upgrades and newer and better systems at vast cost - it's a conspiracy to lock you in I tells ya, get out whilst the goings good.

  5. I'm surprised they don't use UPS, FedEx by The_Rippa · · Score: 5, Insightful

    I'm suprised they don't strike up a deal with UPS, FedEx, and other companies that travel around alot that allows them to hook up receivers and use it to grab data that they can compare to their db.

    Should be easy to tell if a street is new, changed, or whatever. Then they'd just have to send someone out there to verify the new data.

    I'm actually surprised that this is how they do it. I've always assumed they hire people to drive over every road, but I figured there was a much better way to collect what I'm sure is a shitload of data.

    I want Navtech to team up with a couple of the large carriers, like Schneider National, Werner Enterprises, JB Hunt and the other large trucking companies. These 3 companies, and many more, already have GPS transponders in the truck that track their locations and report back in realtime via Satellite.
    Now, when a driver sees major road construction, etc, on major interstates they simply hit a button on their QualComm OmniTracs unit marking it as such. After so many drivers have done this, it marks the area as being under construction, with a little bit of info about what's going on (resurfacing, 3 lanes closed westbound from 9pm-4am at milemarker 139 to 177 until 12/16/03) and mapquest inturns adds that data to it's routing database.
    This would be an excellent way for mapquest to add a pay-for service that I for one would definately use.
