Real world maps

I would very much like to see real-world maps for turn-based tactics games. There are so many real-world locations that would be awesome for such a game, for example historic or well-known buildings. I suspect it would be possible to semi-automate the creation of such maps by walking round the building with cameras, GPS and various other sensors for measuring space (e.g. a Kinect sensor), much like Google is doing with its Art Project.

Obviously, these real-world maps would be excellent for real-time games as well, but who would want to play those...
