Description:
Abstract:
This data set provides a Digital Elevation Model (DEM) for Antarctica to 81.5 degrees south latitude, at a resolution of 5 km. Approximately twenty million data points were used to generate this data set. Data points were derived from ERS-1 radar altimetry during the geodetic phase from March 1994 to May 1995.

Attribute_Accuracy_Report:
Various methods were applied to improve the accuracy of elevation estimates over the Antarctic ice sheet, including waveform tracking, slope correction, data filtering (tests for return-echo waveform shape, backscatter coefficient, and retracking correction values for each altimeter height estimate), and removal of anomalous orbits.
