What Does It Take to Map The World? Time..
Wednesday, August 12th, 2009.. And a lot of resources. An interesting article on CNN about what is behind Tele Atlas’s constantly updating base road data.
Tele Atlas gets this information by combining satellite imagery, local, state and federal maps and most importantly, putting the rubber to the road in its Mobile Mapping Vans.
Now what is interesting are their vans, like the Google street view vehicles, they are also taking high resolution images as they drive around. But this is not for street view (thought it probably could be), it is for getting road information such as number lanes, speed limits, ramp layouts and road types.
