Wow, I just thought: Google AirView, alongside Google StreetView. A fleet of GoogleDrones making 360 degree airborne HD camera pictures at various levels above the ground. Meaning you won’t just be able to walk a place in StreetView, but also hover above it for elevated views from anywhere. It would fill the gap between the satellite photography, which can only go down so far and can’t go sideways to the horizon, and the Google StreetView.
