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. Virtually visit any place in the world. Look across the Andes, into the Grand Canyon, over the Alps, or along the African Sahara.
World Wind is open-source and completely free to use. Zoom in and check out your neighborhood, find your backyard pool, the possibilities are endless.
World Wind really needs a high-speed DSL/Cable connection to download satellite imagery, and a Geforce2/Radeon 7500 and above for graphics acceleration. The initial download package is around 170MB.
