Thanks for all your help on the sites to vector question. I think I'm on
my way to figuring it out.
Is the process I am using to obtain the data I need a reasonable way to go
about it, or am I missing something (not having any real GIS training or
a) I used m.proj2 to convert my site location to the appropriate projection.
b) defined the site with s.in.ascii, and converted it to a raster using
c) created the buffer zone using r.buffer
d) patched the landcover map in the buffer zone with r.patch -z
e) calculated statistics with r.stat -c
