It's possible to download Google Earth's 3D model, at the resolution in your link, for any area where they show 3D buildings/landscape. It's not something they facilitate and definitely requires something of a hack, but it does work. Then you can get the model into Blender, SketchUp, etc. and start editing it to add or remove buildings and so on.

Would be interested to know whether that's technically legal. I mean, they put it out there on their website, right?
