This is the most recent version of these data.
Version Summary
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)

Overview

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

How To

Many NSIDC DAAC data sets can be accessed using the NSIDC DAAC's Data Access Tool. This tool provides the ability to search and filter data with spatial and temporal constraints using a map-based interface. Users have the option to
We recommend using the Geospatial Data Abstraction Library (GDAL) to convert GeoTIFF files into a different format.
We recommend using the Geospatial Data Abstraction Library (GDAL) or a GIS to reproject geoTIFF files.
