World Wind

World Wind is an open source (released under the NOSA license) virtual globe initially developed by NASA's Learning Technologies project. World Wind allows any user to zoom from outer space into any place on Earth. World Wind uses satellite imagery and elevation data to allow users to experience Earth terrain in visually rich 3D, just as if they were really there. Virtually visit anyplace in the world. Look across the Andes, into the Grand Canyon, over the Alps or along the African Sahara.

The program overlays NASA and USGS satellite imagery, aerial photography, topographic maps, Keyhole Markup Language (KML) and Collada files. Organizations across the world use World Wind to monitor weather patterns, visualize cities and terrain, track the movement of planes, vehicles and ships, analyze geospatial data, and educate people about the Earth.

World Wind is different from a 3D globe like Google Earth because it is not a completed application targeted at end users.  Instead, it is an SDK (software development kit) that software engineers can use to build their own applications.  World Wind provides a geographic rendering engine for powering a wide range of projects, from satellite tracking systems to flight simulators.
