High Quality Content by WIKIPEDIA articles! World Wind is an open-source (released under the NOSA license) virtual globe developed by NASA and the open source community for use on personal computers. Old versions need Microsoft Windows but the more recent Java version, World Wind Java, is cross platform and provides a suite of demo apps. The World Wind Java version was awarded NASA Software of the Year in November 2009. The program overlays NASA and USGS satellite imagery, aerial photography, topographic maps, Keyhole Markup Language (KML) and Collada files.
