Google Remaps, Drops Tele Atlas
Over at APB, Tele Atlas appears to have confirmed that Google has dropped them as a map provider in the USA and is now using in house data.
“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.”
I noticed a few changes last night and couldn’t quite figure out what was happening– but this now explains things. You can also now report map errors to Google through their interface.
Determining overall map quality based on small sample sizes is a dangerous thing, but in the few places I’ve checked I’ve seen numerous mapping errors that are not errors in either the Tele Atlas nor Navteq maps.
There is a certain “map psychology” I’ve seen happen when vendors change mapping providers. People tend to see but not report on improvements, thinking it was an incremental update. But when things get worse you see lots of chat about the deficiencies.
Over the next few weeks I’d expect to see a good number of people complaining about the change saying it is a step backwards in map quality– again, people tend to notice things going backwards more than improvements. But I’d caution against making such hasty conclusions based on such tiny sample sizes. I’ve seen a good number of errors in the new Google Map, but my sample size isn’t big enough yet to draw any statistically relevant conclusion.
