NASA sentinel-2 Project

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, consists of surface velocity estimates for selected Greenland Ice Sheet outlet glaciers. Velocity fields were generated by tracking visible features in optical images acquired by the U.S. Geological Survey (USGS) Landsat 8 Operational Land Imager (OLI) and the European Space Agency (ESA) Copernicus Sentinel-2A and Sentinel-2B satellites....本数据集是美国国家航空航天局（NASA）「面向研究环境的地球系统数据记录制作（MEaSUREs）」计划的组成部分，包含经筛选的格陵兰冰盖出口冰川的表面速度估算数据。速度场通过追踪美国地质调查局（USGS）陆地卫星8号（Landsat 8）运行陆地成像仪（OLI）以及欧洲空间局（ESA）哥白尼哨兵-2A（Sentinel-2A）、哨兵-2B（Sentinel-2B）卫星获取的光学影像中的可见特征生成……
