territory polygons in grass (fwd)

[A.B. South]

A year or so ago I tried to generate territory polygons in grass. The way 
I eventually ended up doing it involved using r.in.poly which creates a 
raster polygon from a text file containing coordinates. I remember this 
being time consuming and having to worry about which order the points 
were in the file, and even then it appeared to have a funny bug that lead 
to some of the polygons having additional lines dropping to the S edge of 
the map.

Instead I would recomend using a home range analysis package that will do 
all 
the stuff you want for you (its best to avoid re-inventing the wheel if 
possible!). You can get CALHOME for free on the net from:

http://www.uni-sb.de/philfak/fb6/fr66/tpw/telem/software/calhome.htm

This should do the job. You should be able to output text files from 
grass containing the coordinates of the vertices and then shunt the file 
straight into CALHOME.

Hope this is some help.
I'd be interested in what other replies you get.

Cheers
