Landsat 8 是美国陆地卫星计划（Landsat）的第八颗卫星，于2013年2月11号在加利福尼亚范登堡空军基地由Atlas-V火箭搭载发射成功，最初称为“陆地卫星数据连续性任务”（Landsat Data Continuity Mission，LDCM）。Landsat 8上携带陆地成像仪（Operational Land Imager ，OLI）和热红外传感器（Thermal Infrared Sensor，TIRS）。\n
OLI陆地成像仪包括9个波段，空间分辨率为30米，其中包括一个15米的全色波段，成像宽幅为185x185km。热红外传感器TIRS包括2个单独的热红外波段，分辨率100米。\n
本数据集包含黄河上游流域Landsat OLI的L1级数据产品,数据均来源于美国地质调查局网站（https://earthexplorer.usgs.gov/)。\n

The OLI includes 9 bands with a spatial resolution of 30 meters, including a 15-meter panchromatic band, and an imaging swath of 185x185km. The Thermal Infrared Sensor (TIRS) includes 2 separate thermal infrared bands with a resolution of 100 meters.
This dataset contains L1-level data products from the Landsat OLI for the upstream basin of the Yellow River, all sourced from the United States Geological Survey website (https://earthexplorer.usgs.gov/).
The spatial resolution of this data product is 30m, with cloud cover less than 10%. The spatial range is: 95°59′13.6392″-111°06′41.4396″; 32°27′56.5128″—41°50′22.9992″.
