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.

Version Description

Version 2 includes the following changes: * DEM generated from both in-track image pairs and cross-track images. * DEM registered to ATLAS/ICESat-2 L3A Land Ice Height, Version 5 (ATL06, V5) * Algorithm revised to utilize large increase in available DEM data since Version 1 * Data set consists of a single DEM created from all available data ("fit," "reg," and quarterly DEMs are not provided)
