Earth3D

Earth3D
Earth3D is a program that visualizes the earth in a realtime 3D view. It uses data from NASA,USGS, the CIA and the city of Osnabrück.


The program's features are
  • viewing the earth as a whole
  • zooming in until countries, cities and even single houses become visible (if I had such maps, so this is currently limited to the city of Osnabrück, Germany)
  • embedding external data like current earthquake positions or cloud data
