Landsat is a joint program of NASA and the United States Geological Survey, which provides the longest continuous space-based observation record in the world. Every day, the Landsat series satellites will provide important information to assist land managers and decision-makers in making decisions on the earth's resources and environment. Launched on April 15, 1999, Landsat7 is equipped with the Enhanced Thematic Mapper Plus. It has a panchromatic band with 15m spatial resolution, onboard, full aperture, 5% absolute radiation calibration, a thermal infrared band with 60m spatial resolution, and onboard data recorder. On May 31, 2003, the scanning line corrector of Landsat7 satellite had a permanent failure, causing the sensor line of sight to be serrated along the ground. Launched on February 11, 2013, Landsat 8 is equipped with two sensors: Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS). The OLI is equipped with a 4-mirror telescope and a 12 bit quantitative push broom sensor, which can collect visible, near-infrared, shortwave infrared and panchromatic wave band data. Compared with the ETM+carried by Landsat 7, OLI provides two signal 2 spectral bands: a band specially tailored for monitoring cirrus clouds and a band used for coastal observation. This dataset includes the Landsat7 ETM+dataset from 2000 to 2012 and the Landsat8 dataset from 2013 to 2021. Data products include C1-L1, C2-L1, C2-L2.
