Google is no longer using Tele Atlas maps for America. Instead, it is using its own map data.
Google: “We’ve worked directly with a wide range of authoritative information sources to create a new base map dataset. In our experience, these organizations that create the data do the best job of keeping it accurate and up-to-date. For example, in the US there are a number of publicly accessible geospatial datasets created by the government for the Census, land surveying, and transportation.
The best part about this new dataset is that we’ve been able to add a lot of new, detailed information to Google Maps – information that helps people better explore and get around the real world. For example, college students will be pleased to see maps of many campuses; and cyclists will now find many more trails and paths to explore. Soon we even plan on providing you with biking directions to take advantage of this new data. Of course, in the true Google spirit of “launch and iterate,” we plan to work with more data sources to add new features in the map.” (Source: Google Blog)
Tele Atlas:“Tele Atlas confirms that Google has decided to stop using Tele Atlas map data for the U.S. Google will now use its own map data. Our relationship with Google for map coverage continues outside of the U.S. in dozens of geographies.” (Source: All Points Blog)
Additionally, Google has introduced a ‘Report a problem’ feature that will allow users to report errors on its map. Google claims all these reports will be checked and corrected within a month.
