Cartographers hit the road to bring updated online maps by the St. Louis Post-Dispatch tells the story behind the individuals who draw the maps we use in our GPS devices or via our favorite online mapping software.
NAVTEQ is the company that MapQuest, Google, Yahoo and others use for their mapping database. They travel the globe, document new roads, old roads, construction issues and more. One thing I found particularly interesting is what construction effort warrants a map change at MapQuest;
MapQuest manager Christian Dwyer said his company typically adjusts its maps any time a construction project exceeds three months; the Highway 40 project is expected to run about three years.
The story also gives stats on the most popular online mapping services. MapQuest leads with a 68 percent share of those seeking maps online in November 2006, followed by Google at 28 percent and Yahoo at 27 percent. Stats are from Nielsen/NetRatings and don’t add to 100 percent because some people use more than one service.
