Google's virtual globe application that allows users to view 3D buildings, imagery, terrain, any other information stored in KML files.

Google Earth is a virtual globe, map and geographical information software application that runs on Windows, Mac, and Linux platforms.

It maps the Earth with images obtained from satellite imagery, aerial photography and 3D globe combined with multiple independent layers such as border labels & outlines, roads, 3D buildings, traffic/weather data, and more. Additional information can be viewed by opening other KML files, and the software allows new KML files to be easily produced.
