And if you download their applet, you'll get their 3D cities. They have most of the cities in the US & Canada and some european cities in 3D. You can go 360 around any given building and 'fly' thru the 'canyons' of NYC. It takes a computer w/ decent speed and memory and a fast internet connection.
The cities have been flown (aerial digital camera, hi resolution about 3cm @ 5000 ft) typically within the last year.
