Researchers from Georgia Tech have devised methods to take real-time, real-world information and layer it onto Google Earth

They use live video feeds (sometimes from many angles) to find the position and motion of various objects, which they then combine with behavioral simulations to produce real-time animations for Google Earth or Microsoft Virtual Earth.

They use motion capture data to help their animated humans move realistically, and were able to extrapolate cars’ motion throughout an entire stretch of road from just a few spotty camera angles

Now where would you happen to have loads of CCTVs you could use to spy on everybody realtime? I wonder…
