Google have confirmed that they have stopped using Tele Atlas as their preferred map data provider for Google Maps in the United States.
Google have used their data gathering experience to harvest data from other parties as well as the rich data contained in Streetview and and satellite/aerial photography that they already have from their other services to create their own map data. Google now allow you to report map errors directly to them.
What does this mean? Well financially for Tele Atlas it’s probably going to take make a dent in their balance sheet, but it seems that this might be the first of many regions to switch away from Tele Atlas maps.
