Google Maps updated with 25 million new building footprints
Google Maps has gone berserk with updates in the last few days and weeks, and coincidental or not all those updates help us realize just how much effort Google is putting in creating one of the best maps applications on the market. Google Maps last week got updated with thousands of miles of roads added in Street View, and now both the mobile and desktop version of Maps get 25 million new building footprints.

25 million sounds impressive and it indeed is. Most of those footprints are for large U.S. cities and metros. Los Angeles, Chicago, Miami, Houston and the San Francisco Bay Area are some of the areas where the changes will be most obvious. The additions however will also touch on the whole United States.

But how did Google manage to add so many new footprints? It is, of course, using aerial images and combines this raw data with computer vision processing to come up with dimensions and shapes for buildings. 

“This process enables us to provide more building footprints and a more comprehensive and detailed map than ever before,” Google said.

Actually, this is the same core process used in Google 3D Maps. In the meantime, if you're still wondering whether Google Maps is being developed for iOS and the iPhone 5 the answer is not clear. It's all under consideration, and lastly Google CEO Larry Page said that while he would like Google to serve Maps to all platforms, the walled-garden approach (like the one in the App Store) stops or at least slows that down.

Google maps kick Nokia Maps out of the competition as soon as possible.The only difference between both these maps is database.

Nah, I still prefer the typography in Nokia's maps. Makes it look a lot cleaner.
Nokia maps looks better, Google maps is better (as a map).

Exactly. Free GPS, turn by turn navigation is one of the reasons why I chose Android over the iPhone in 2010. Was close to getting an iPhone too. I am satisfied with my decision....and it all started with me getting the Droid 1.

@weedl

what would you expect for getting free map service on a free os distributed. WE PAID ALMOST NOTING BUT THE ADS! so it is already more than expected service. but, i wonder, why did my small home town get luckily 100m detailed! Just try search Magetan Jawa Timur Indonesia on gmaps.
