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 3D.
This near-worldwide set of 609 satellite imagery mosaics, marketed as 1990 GeoCover by Land Info Worldwide Mapping, is from Landsat 4/5 TM and includes three 30m multi-spectral bands 7-4-2. The Landsat images have been ortho-rectified, tonally balanced, mosaicked, tiled, and wavelett compressed.
This worldwide set of 770 satellite imagery mosaics, marketed as 2000 GeoCover by Land Info Worldwide Mapping, is from Landsat 7 Enhanced Thematic Mapper (ETM+); the 15m band was pan-sharpened with 30m multi-spectral bands 7-4-2. The Landsat images have been ortho-rectified, tonally balanced, mosaicked, tiled, and wavelett compressed.
Ortho-rectified mosaics with 25 pixel resolution are comprised from 369 satellite scenes taken between July 1999 and September 2000. Both distinct mosaics were produced by using different spectral bands.
