An overview of the Landsat Program and active missions, Landsat data products and data access, and available tools and services. Since 1972, the joint U.S. Geological Survey (USGS)/National Aeronautics and Space Administration (NASA) Landsat series of Earth Observation satellites have continuously acquired images of the Earth’s land surface. Eight satellites have added more than 11 million Level-1 scenes to the USGS EROS Archive.
Landsat products are used to monitor, assess and project how changes in land use, land cover, and land condition affect people and nature. Current products available include, Level-1 (scaled calibrated radiance), Level-2 (atmospherically corrected global surface reflectance and surface temperature), Level-3 Science Products (Dynamic Surface Water Extent, Factional Snow-Covered Area, Burned Area) and U.S. Analysis Ready Data (ARD).
Landsat products can be downloaded or accessed via EarthExplorer, Amazon Web Services (AWS) Commercial Cloud, Machine to Machine Application Programming Interface (API), GloVis, LandsatLook Viewer, and the Earth Resources Observation and Science (EROS) Science Processing Architecture (ESPA) on demand interface.
