I take it all back, give google their due.  They must have seen “world wind”, which is also fantastic, and thought we could do that in maps.

Yes Google have satellite imagery on maps now, it uses the same ajax techniques to awesome effect due to, what worldwind calls the USGS urban maps.

Now if they could just apply mipmapping at various levels of magnification to smooth out the transisition and mix land sat 7 pictures with urban ortho.

Great work.
