I think that given that Google already has 3D depth coverage from its street view machines [1], it should be possible to combine that data with some medium resolution overhead 3D scans to create something similar, and likely even higher quality at the street level.
I wonder why Google hasn't done it yet. I don't think there are any real technical limitations. It may be that getting it fast is hard and the usefulness from an end user perspective isn't there yet?
