I just came across a pretty cool app for your PC called World Wind. It's basically a 3D globe that you can zoom into and view topography and urban areas. You can get placenames and a bunch of other really cool information.

Check it out here. My only real gripe is that it's not realtime, and you need one heck of a PC to run it. Pretty bad slowdown on a 1800 with a GeForce 2. That and there's a lot of extra downloading to do, like the .Net framework (extra 28mb) and some extra DX drivers.
