Detailed elevation map of Greenland's ice, from GeoEye and WorldView satellite cameras

MEaSUREs Greenland Ice Mapping Project (GrIMP) Digital Elevation Model from GeoEye and WorldView Imagery V002
cryosphere NASA NSIDC_CPRD Level 3 GeoTIFF
In plain English

What it measures. A detailed elevation map of the Greenland Ice Sheet, showing the height of the ice surface at very fine resolution.

How it's made. Created from pairs of overlapping high-resolution images taken at slightly different angles by the GeoEye and WorldView commercial satellites, then aligned to ICESat-2 laser measurements for accuracy.

How & where you'd use it. Helps scientists measure the shape and changing height of Greenland's ice, a key piece of tracking ice loss and sea level rise.

Official description

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.
