Who Makes MapQuest's Maps? 338
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."

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.

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.

however, i know from my own county (middle of nowhere colorado) that the maps are seldomly updated in digital format -- my girlfriend (IT manager for the county) was updating 20-year-old maps, putting the incremental changes back into the database. they were planning on printing new maps for surveyors, etc., and hadn't done it recently (20 years.) although the information is publicly available (and the paper maps are up to date,) there's no guarantee it's available digitally, or digitally & correctly. then again, most of this information was about property ownership and boundaries -- maybe they keep the road information more up to date.

(the UPS/Fedex people get a bit confused when you give them one address and they have the other one available to them in their mapping system.)
from what i understand, information of this sort is kept using fairly standard software like ESRI ArcGIS (unless it's just in the "road guy"'s head, as it is for us most of the time,) so most counties would have very similar (or identical) database layouts. shouldn't be too hard to coordinate. getting them to -send- you updates might take some convincing though, or even to make the updates digital.

It would be easy to relate this data to roads, popular stops, even events that occur along the route. Car accidents, Bill Clinton having sex in a car, gawkers slowing down, all are events that would trigger increases in phone traffic.
