The Landsat programme provides a global archive of satellite imagery and is managed and operated by the U.S. Geological Survey (USGS). Landsat-7 is the seventh satellite of the Landsat programme.

Landsat-7 was the next in a long history of land remote sensing spacecraft, spanning 40 years of multispectral imaging of Earth's surface, starting with the launch of Landsat-1 in 1972. In particular, the ETM+ continued the database of Earth imagery begun in 1982 by the Landsat-4 Thematic Mapper (TM), providing the same spectral bands for consistent change detection.
