Group: Summary

   This data set provides a 100 meter resolution surface topography Digital 
   Elevation Model (DEM) of the Antarctic Peninsula. The DEM is based on Advanced 
   Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital 
   Elevation Model (GDEM) data. The original GDEM data are accurate for coastal 
   regions of the Antarctic Peninsula, but contain large errors on snow- and 
   ice-covered regions. This data set was developed using a new method 
   specifically for smoothing erroneous regions, and has a mean elevation 
   difference of - 4 meters (±25 m Root Mean Square Error [RMSE]) when compared 
   to data from the NASA Ice, Cloud,and Land Elevation Satellite (ICESat), 
   although elevation accuracies are lower on mountain peaks and steep-sided 
   slopes.

   Data are available via FTP in GeoTIFF and ASCII formats.
