This shows some important uses of Google Street View: helping tourists plan itineraries and conducting virtual field trips.
You can also view an impressive 3D model of Disneyland Paris in Google Earth. "More than 85,000 photos (450GB worth) were taken over a 20 day period for this project. The castle alone is comprised of over 354 textures derived from over 2,000 photos. (...) There are over 500 unique landscape elements that were created to make the park look as realistic as possible."
The unofficial Google Earth blog reports that Google added a lot of new 3D buildings. "Google has been slowly adding cities using an unpublished methodology where vast numbers of buildings for large areas of cities are being rendered in 3D with photorealistic textures. The photos appear to be aerial in some cases, in others they seem to be from the ground. But, they are using an at least semi-automated process judging from the cases where some buildings are not properly dressed with the photo textures."
