Google Nexus One owners today can download the first version of Google Earth for the Android platform. While a version of the app has been available on the Apple iPhone OS for some time, Google’s own Earth-sized mapping app has finally come to Google’s own OS. Most of the same features are available on the Android version, including layers for points-of-interest and terrain mapping, as well as a Panoramio layer to view user-submitted pictures of various spots around the globe. Unlike on the iPhone OS version, Google Earth users on Android OS 2.1 will not be able to sign into their Google profiles to load their own maps from Google’s My Maps service. The Android version also currently lacks the accelerometer support found on the iPhone. The Google Earth app, which appears simply labeled “Earth” in Android, is available for free from the Android Market.
