KML 2.1+ file format for Google Earth and Google Maps

KML is the file format used by Google Earth and in Google Maps. With KML 2.1 and above, you can import 3D models—such as buildings, bridges, monuments, and statues—in the COLLADA intermediate file format. Models are defined independently of Google Earth in their own coordinate space, using applications such as SketchUp, 3D Studio Max, Softimage XSI, or Maya. When a 3D model is imported into Google Earth, it is translated, rotated, and scaled to fit into the Earth coordinate system. Models already loaded into Google Earth can be repositioned and resized using the element feature.
