Zoom In From Outer Space Interactive Live Satellite Program BetaFrom NASA

World Wind, an open source 3D interactive world viewer, was created by
NASA's Learning Technologies (http://learn.arc.nasa.gov) project, and
released in mid-2004. It is now developed by NASA staff and open source

At its simplest you can think of World Wind as a desk globe, however
World Wind is not a simple desk globe.

World Wind allows any user to zoom from outer space into any place on
Earth. World Wind leverages 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.

Unlike your desk globe World Wind can display thousands of placenames
all over the world, from Country capitals to villages in sparsely
populated regions. You can see country borders, and in some cases
intracountry borders such as US states.

World Wind can also be expanded to include additional imagery and data.
There have already been a number of add-ons created, from Norway's
Prehistoric Hillforts to additional planets.
