The USGS Landsat Program Data refers to a comprehensive collection of satellite imagery acquired by the Landsat series of Earth observation satellites managed by the United States Geological Survey (USGS). These data products provide valuable, high-resolution, multispectral images of the Earth's surface, enabling a wide range of applications such as environmental monitoring, land use planning, agriculture, forestry, and climate change studies. The Landsat program has been operational since 1972 and offers a longstanding, continuous record of Earth's surface changes over nearly five decades.
