Landsat Project

As a joint initiative between the U.S. Geological Survey (USGS) and NASA, the Landsat Project provides repetitive acquisition of high resolution multispectral data of the Earth's surface on a global basis. The data from the Landsat spacecraft constitute the longest record of the Earth's continental surfaces as seen from space.  Today's use of Landsat data has evolved, becoming not only a fundamental data source for addressing basic science questions but also has come into its own as a valuable resource for decision makers in such diverse fields such as agriculture, forestry, land use, water resources and natural resource exploration. Landsat data products are processed and made available for download to all users at no charge via EarthExplorer, GloVis, and the LandsatLook Viewer.

The Landsat site provides links and information about the many applications of Landsat data, many of which have specific value in conducting impact or vulnerability assessments, such as mapping urban heat and assessing impacts from drought. 

During the summer of 2016, the USGS started making changes to manage the Landsat archive as a tiered Collection of Landsat data. A Collection will provide a stable environmental record. If significant radiometric or geometric changes are required, all data will be reprocessed and a new Collection will be released. The tiered structure clearly identifies the subset of the Landsat archive that meets radiometric and geometric criteria suitable for time series analysis and the creation of data stacks/cubes, while continuing to provide access to the entire Landsat archive.
