Group: Summary

   This data set provides a 1 km resolution Digital Elevation Model (DEM) of 
   Antarctica. The DEM combines measurements from the European Remote Sensing 
   Satellite-1 (ERS-1) Satellite Radar Altimeter (SRA) and the Ice, Cloud, and 
   land Elevation Satellite (ICESat) Geosciences Laser Altimeter System (GLAS). 
   The ERS-1 data are from two long repeat cycles of 168 days initiated in March 
   1994, and the GLAS data are from 20 February 2003 through 21 March 2008. The 
   data set is approximately 240 MB comprised of two gridded binary files and two 
   Environment for Visualizing Images (ENVI) header files viewable using ENVI or 
   other similar software packages. The data are available via FTP.
