资源简介：
This data set consists of an enhanced resolution digital elevation model (DEM) for the Greenland Ice Sheet, derived from sub-meter resolution, panchromatic stereoscopic imagery collected by the GeoEye-1, WorldView-1, -2, and -3 satellites operated by Maxar Technologies.
The DEM was created from in-track image pairs (i.e., both images collected minutes apart along the same orbital pass) and cross-track images (i.e., from different orbits) within the in-track imaging geometry and maximum time separation criteria. The DEM is registered to ATLAS/ICESat-2 L3A Land Ice Height, Version 5 (ATL06, V5) data collected in the summers of 2019 and 2020.
See Greenland Ice Mapping Project (GrIMP) for related data
本数据集包含一套面向格陵兰冰盖（Greenland Ice Sheet）的增强分辨率数字高程模型（digital elevation model, DEM），该模型由马克萨尔技术公司（Maxar Technologies）运营的GeoEye-1、WorldView-1、WorldView-2及WorldView-3卫星采集的亚米级分辨率全色立体影像生成。
该DEM基于沿轨影像对（即沿同一轨道过境时段内隔数分钟采集的两幅影像）以及符合沿轨成像几何与最大时间间隔准则的交轨影像（即来自不同轨道的影像）构建而成。本DEM已与2019年和2020年夏季采集的ATLAS/ICESat-2 L3A陆地冰高程第五版（ATL06, V5）数据完成地理配准。
