USGS Puts Landsat Data Online

The U.S. Geological Survey (USGS) has made selected Landsat 4, 5 and 7 satellite data available online at no cost. Orthorectified Landsat data are available for download from the Global Visualization Viewer and Earth Explorer.

The Landsat Orthorectified data collection is a global set of high-quality, relatively cloud-free orthorectified Landsat 4-5 Thematic Mapper and Landsat 7 Enhanced Thematic Mapper Plus imagery. The datasets were selected and generated through NASA's Commercial Remote Sensing Program, and provide two full sets of global coverage over an approximate 10-year interval (circa 1990 and circa 2000) and total nearly 16,000 scenes. USGS plans to add other data sets as they become available, including the Landsat Orthorectified Multispectral Scanner data set (circa 1975).

Users can download an entire scene, containing all bands, metadata, jpeg and header information in a single zipped format file. For more information go here.
