directions?
Where those driving directions really come from - Feb. 27, 2006
Navteq supplies the raw map data that underlies those directions. That data isn’t as raw as you might think, though. Unlike paper maps, Navteq’s digital maps have to include details about which roads are one way, which way, and things like whether left turns are illegal Monday through Friday, excluding holidays, from 7:00 a.m to 10:00 a.m. unless you’re driving a bus.They spend about half their time driving around gathering data about every road, large and small, in their designated region of the country. The other half of their time is spent sorting out all that data.
interesting article, a bit short, some random stuff like the fact that the computer is inside a locked metal box, but they offer no explanation why, its kinda like, good for you.
anyway, interesting stuff
