An open source 3D interactive world viewer created by NASA’s Learning Technologies project, released in mid-2004. It is now developed by NASA staff and open source community developers. World Wind lets you zoom from satellite altitude into any place on Earth. Leveraging Landsat satellite imagery and Shuttle Radar Topography Mission data, World Wind lets you experience Earth terrain in visually rich 3D, just as if you were really there.
World Wind provides geospatial visualization technology via extensible and modular components that can be incorporated into any application. World Wind spurs innovation by involving the world community in advancing this cross-platform Java-based technology.
