Google Earth and Moon

The whole world is covered with medium resolution imagery and terrain data. This resolution allows you to see major geographic features and man-made development such as towns, but not detail of individual buildings. Additional high-resolution imagery which reveals detail for individual buildings is available for most of the major cities in the US, Western Europe, Canada, and the UK. 3D buildings are represented in 38 US cities (the major urban areas). Detailed road maps are available for the US, Canada, the UK, and Western Europe. And Google Local search is available for the US, Canada, and the UK.
