Landsat Satellite Imagery
U.S. Geological Survey, National Aeronautics and Space Administration
Landsat is moderate spatial-resolution (30-meter) imagery that provides large areas of repeated data coverage at a scale that enables users to see detailed human-scale processes, such as urbanization, but not individual houses.
Since 1972, Landsat program satellites have collected consistent spectral imagery of the Earth’s continents and surrounding coastal regions. This historical archive is unmatched in quality, detail, coverage, and length, enabling people to study many aspects of the planet and evaluate the dynamic changes caused by natural processes and human practices.
