NASA World Wind

3D satellite images from NASA

Our Rating: (Very Good)

World Wind is an open source project, that lets you zoom from satellite altitude into any place on Earth. It uses Landsat satellite imagery and Shuttle Radar Topography Mission data, as well as several data sources that provide historical and information on storms, fires, floods and other major events, as well as important landmarks with links to additional information on the web. World Wind also includes a full copy of the Blue Marble, a true-color image of the entire Earth as seen on NASA's Earth Observatory. Other data sources include Land Sat 7, SRTM, NASA SVS, MODIS, GLOBE as well as country and US state borders and city names. NASA World Wind also provides imagery of the moon. Even though the program appears similar to Google Earth, it covers a much wider range of data sources, however it is not nearly as user-friendly and requires an in-depth look at the documentation.
