Orthorectified Landsat Digital Data Now Available From USGS

The US Geological Survey (USGS) now offers, at no cost, selected Landsat
4, 5 and 7 satellite data. Orthorectified Landsat data are available for
free download from the Global Visualization Viewer (GloVis) at
http://glovis.usgs.gov and Earth Explorer at http://earthexplorer.usgs.gov
.
The Landsat Orthorectified data collection is a global set of
high-quality, relatively cloud-free orthorectified Landsat 4-5 Thematic
Mapper (TM) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+) imagery.
Selected and generated through NASA's Commercial Remote Sensing Program,
the datasets provide two full sets of global coverage over an approximate
10-year interval (circa 1990 and circa 2000) and total nearly 16,000
scenes.  Other data sets will be added as they become available, including
the Landsat Orthorectified Multispectral Scanner (MSS) 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 regarding Orthorectified data, please go to

The Landsat Program is the longest running program providing vital images
of the Earth?s surface from space. The first Landsat satellite was
launched in 1972 and since then, Landsat satellites have been providing a
constant stream of moderate-resolution images. In 1999, the Landsat
Program took a giant leap forward technologically with the launch of
Landsat 7. The instruments on the Landsat satellites have acquired
millions of images of the surface of the planet, providing a unique
resource for scientists who study agriculture, geology, forestry, regional
planning, education, mapping and global change research.

The USGS serves the nation by providing reliable scientific information to
describe and understand the Earth; minimize loss of life and property from
natural disasters; manage water, biological, energy, and mineral
resources; and enhance and protect our quality of life.
