Landsat是美国航空航天局与美国地质调查局的联合计划，该计划提供了现有的世界上最长的连续空基观测记录。每天，Landsat系列卫星都会提供重要信息，以辅助土地管理者和决策者就地球资源和环境做出决策。Landsat7发射于1999年4月15日，这颗卫星搭载了Enhanced Thematic Mapper Plus（增强型专题制图仪）。拥有一个15m空间分辨率的全色波段，板载、全光圈、5%绝对辐射校准，拥有一个60m空间分辨率的热红外波段，板载的数据记录仪。2003年5月31日，Landsat7卫星的扫描线校正仪发生永久性故障，导致传感器视线沿地面呈锯齿状。Landsat 8发射于2013年2月11日，搭载了两颗传感器：Operational Land Imager（OLI）和 Thermal Infrared Sensor （TIRS），OLI带有4镜望远镜和12位量化推扫式传感器，能够收集可见光、近红外和短波红外以及全色波段数据，相比Landsat 7搭载的ETM+,OLI提供两个信2的光谱带：一个专门为监测卷云的定制的波段和一个用于沿海地区观测的波段。\n
该数据集包含2000年-2012年的landsat7 ETM+数据集和2013-2021年的landsat8数据集。数据产品包含C1-L1,C2-L1,C2-L2。

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.\nThis 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.
