This directory contains ASCII files with simplified outlines of
Benson's snow/ice facies: 

Carl S. Benson, "Stratographic Studies in the Snow and Firn of 
the Greenland Ice Sheet", Research Report 70, U.S. Army Snow 
Ice and Permafrost Rsearch Establishment, Corps of Engineers, 
July 1962.

and Long and Drinkwater's ice facie classification from:

D.G. Long and M.R. Drinkwater, "Greenland Ice-sheet Surface Properties 
Observed by the Seasat-A Scatterometer at Enhanced Resolution," 
Journal of Glaciology, Vol. 40, No. 135, pp. 213-230, 1994. 

Each file contains a numbered list of (#,lat,lon) values which
define particular facie.  A (#,0,0) value denotes a separate 
outline.  See the matlab file LDplot for a sample usage.

Note that the outlines are simplified (i.e., the number of points
have been reduced) and thus have quantization effects.
