Group: Summary

   The Antarctic atlas consists of 28 digital elevation maps which cover all of 
   Antarctica north of 72.1 degrees south at a resolution of three kilometers. 
   Each map contains surface elevations and coordinates for one atlas page 
   covering 16 degrees of longitude. Data were acquired by the Geodetic Satellite 
   (GEOSAT) Geodetic Mission (GM) from March 1985 through September 1986 and are 
   available in both Universal Transverse Mercator (UTM) coordinates, and in 
   latitude and longitude coordinates.

   Data were mapped using the UTM projection in atlas form to decrease the 
   distortion that usually occurs at the poles. Many features of the Antarctic 
   Ice Sheet are shown in more detail than in previous digital elevation models, 
   especially along the margin of the East Antarctic Ice Sheet. A geostatistical 
   mapping technique (Herzfeld et al. 1993) improved the accuracy of surface 
   elevations compared to previous GEOSAT elevation data sets. This atlas will 
   facilitate the monitoring of changes in surface elevation that could indicate 
   mass changes in the Antarctic Ice Sheet.
