Landsat-8 is the eighth satellite of the U.S. Landsat Program, jointly developed by NASA and the United States Geological Survey (USGS), and successfully launched on February 11, 2013. The Landsat 8 satellite is equipped with two sensors: OLI (Operational Land Imager) and TIRS (Thermal Infrared Sensor). The OLI includes 9 spectral bands with a spatial resolution of 30 meters, among which there is a 15-meter panchromatic band, and its imaging swath is 185 km × 185 km. The TIRS includes two separate thermal infrared bands, with a spatial resolution of 100 meters.
