Google has compiled a Google Earth version compatible with both iPod Touch and the iPhone, which also has 3D vision. The PC application itself has achieved more than 400 million downloads since its debut in 2005.
According to the Google Mobile blog, the application has been used by “people from around the world have used it to view their house, research travel destinations, learn how to make the world a better place, find local businesses, and view geo-located photos.”
The touch interface on the two devices will be a bonus as you will be able to navigate by the means of swiping your finger, title the view as you tilt the phone, zoom by tapping on the display, and make use of the built-in GPS to search nearby attractions.
Google Earth is downloadable in the App Store in Apple iTunes.
