Group: Summary

   This data set provides grounding line and hydrostatic line locations for the 
   Antarctic coastline and islands around Antarctica. The data are derived using 
   customized software to combine data from Landsat-7 imagery and Ice, Cloud, and 
   land Elevation Satellite (ICESat) laser altimetry, which were primarily 
   collected between 1999 to 2003. The data set also includes elevations along 
   each line, selected from six candidate digital elevation models. The data were 
   developed as part of the Antarctic Surface Accumulation and Ice Discharge 
   (ASAID) project. 

   Data are available via FTP, provided in both ASCII text (.txt) and shapefile 
   (.shp, .dbf, .shx) formats.
