Radarsat Antarctic Mapping Project Digital Elevation Model Version 2
Entry ID: NSIDC-0082

[ Update this Record ]

Abstract: The high-resolution Radarsat Antarctic Mapping Project (RAMP) Digital Elevation Model (DEM) combines topographic data from a variety of sources to provide consistent coverage of all of Antarctica. Version 2 improves upon the original version by incorporating new topographic data, error corrections, extended coverage, and other modifications. The DEM incorporates topographic data from satellite ... View entire text
