World Wind is a virtual globe developed by NASA for use on personal computers running Microsoft Windows. The program overlays NASA satellite imagery and United States Geological Survey aerial photography on a 3D model of the Earth, Moon and Mars. (Venus and Jupiter are also available in the File menu, including the moons Io, Ganymede, Europa and Callisto through the program overlays, all these come without 3D elevation data)

The user interacts with the selected planet by rotating it and zooming in and out. An overlay of five million placenames and political boundaries is included. The software also provides the ability to browse maps and other imagery on the internet using the Open Geospatial Consortium Web Map Service, import ESRI shapefiles and placemarks from kml/kmz files.
