Landsat 计划自1972年起持续对地球成像，提供了覆盖全球、连续完整的地表影像档案。Landsat 8 是 Landsat 系列中最新发射的卫星，于2013年升空，其搭载的传感器共获取11个光谱波段的数据：其中10个光学/近红外波段来自运行陆地成像仪（Operational Land Imager, OLI），2个热红外波段来自热红外传感器（Thermal Infrared Sensor, TIRS）。本数据集代表了 Landsat Collection 2 全球存档中的 Landsat 8 Level-2 数据，影像以云优化 GeoTIFF（cloud-optimized GeoTIFF, COG）格式存储。

The [Landsat](https://landsat.gsfc.nasa.gov/) program has been imaging the Earth since 1972; it provides a comprehensive, continuous archive of the Earth's surface. [Landsat 8](https://www.usgs.gov/core-science-systems/nli/landsat/landsat-8) is the most recent satellite in the Landsat series. Launched in 2013, Landsat 8 captures data in eleven spectral bands: ten optical/IR bands from the [Operational Land Imager](https://landsat.gsfc.nasa.gov/landsat-8/operational-land-imager) (OLI) instrument, and two thermal bands from the [Thermal Infrared Sensor](https://landsat.gsfc.nasa.gov/landsat-8/thermal-infrared-sensor-tirs) (TIRS) instrument. This dataset represents the global archive of Level-2 Landsat 8 data from [Landsat Collection 2](https://www.usgs.gov/core-science-systems/nli/landsat/landsat-collection-2). Images are stored in [cloud-optimized GeoTIFF](https://www.cogeo.org/) format.
