Late last week, Google pushed out 3D buildings for Vienna, Austria. I played with it over the weekend, and it’s amazing! I don’t know the exact numbers, but I’d guess that it’s among the best 3D coverage of any city on the planet. I was floored by the level of detail in Milan a few months ago, but I’m pretty sure that Vienna is even more widely covered.
I highly recommend that you check it out for yourself. Here is a KML to fly directly there, or enjoy this brief video that Google has put together:
Of all of the 3D cities that Google has added to Google Earth, which one is your favorite (and why)?
