This is probably a lot more recent than you were thinking, but there's an app to view what the inner city of my town looked like pre-earthquake. You can use it remotely and as an augmented reality thingy when walking around looking at the demolition sites, although last time we tried that it seemed to have trouble getting the location pinpointed close enough.

eta - Just tried the fake location feature. Kinda interesting but pretty shaky, and could use more 3d models.
