A number of towns decided to give it a go, including: Amherst, Mass.; District of Columbia; Greenville, S.C.; Jamestown, N.Y.; McMinnville, Tenn.; and the Metropolitan Government of Nashville & Davidson County, Tenn.
If you'd like to take a gander at what its all about, you have to switch the "3-D Buildings" layer on in Google Earth 4.3. Then just fly on over to one of the towns listed above.
According to the press release from Google, the idea here is to make "information that was previously confined to government mapping professionals available to the general public through the rich, interactive environment provided by Google Earth."
Pau Ney, director of the Mayor's Office of Economic and Community Development in Nashville, Tenn., is very excited about the project. He said, "Having 3-D models of our city available via Google will provide a convenient, cutting-edge showcase for all our city has to offer, including our neighborhoods, business districts, and recreational, cultural, and entertainment amenities. This is a tool that will undoubtedly contribute to our economic development success."
I took a look at the 3-D model of Washington, D.C. It really is a cool way to to look at the town, and gives you a whole different perspective for how things are mapped out on the ground.
