NASA World Wind 1.4.0

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.
Particular focus was put into the ease of usability so people of all ages can enjoy World Wind. All one needs to control World Wind is a two button mouse. Additional guides and features can be accessed though a simplified menu.
Navigation is automated with single clicks of a mouse as well as the ability to type in any location and automatically zoom into it.
NASA has released World Wind as an open source program to improve its quality through peer review, maximize awareness and impact of NASA research, and increase dissemination of World Wind in support of NASA's mission: To inspire the next generation of explorers ... as only NASA can.
