US: Google has added another layer of detail to its maps for desktop and mobile. Now, besides, streets, parks and bodies of water, users can also see even more building footprints in major cities across the US.

The Web giant debuted this new addition by adding 25 million new building footprints to its map platform. Cities include Houston, Los Angeles, Chicago, Miami and the San Francisco Bay Area.

“As we go about our daily travels, we often rely on buildings to orient ourselves, locate landmarks and navigate from place to place,” Google Maps Engineering Manager Bobby Parikh wrote in a blog post. “This expansion is part of our ongoing effort to provide you with maps that are as comprehensive as possible.

All of the building images also come with height information, which was created by aerial imagery combined with computer vision techniques in order to produce the building shapes. “This process enables us to provide more building footprints and a more comprehensive and detailed map than ever before,” Parikh said.

Google has received a fair amount of acclaim recently for its maps platform. When Apple opted to boot Google Maps from its iOS 6, many users got up in arms and complained that Apple Maps didn”t compare to Google”s. Google has since amped up its mobile Web app but has not said if it will create a specific maps app for iOS.
