Boundary shape

[Jeff P. Hollenbeck]

GRASS users,

The web address given below for FRAGSTATS is not as pertinent to GRASS
users since it a site offering a modified version of FRAGSTATS geared
toward ArcInfo users. 

However, the original FRAGSTATS is available in both a raster and an
ArcInfo vector version. It is a great software and I have found it very
useful.  The official? web location for FRAGSTATS is

http://www.fsl.orst.edu/lter/datafr.htm  -and follow the "Software" link.
