Nasa World Wind - 3D Mapping

Nasa World Wind - Epic Empire:

"Google Earth is phenomenal but now Nasa is introducing a free 3D mapping software called World Wind. The National Aeronautics and Space Administration has combined SRTM elevation data and high resolution LandSat imagery. The interface has been programmed to be the most simplistic and easy to use for everyday users. The 3D landscapes are exceptionally detailed."
