Hi all

I'm a beginning Grass-user, using GIS for hydrological applications.
I have a raster file of a catchment (0/1 values resp. outside/inside 
catchment) as well as a file with the locations of 3 weather stations 
within this catchment. Out of this, I want to create a raster file in 
which the catchment is divided in 3 areas by means of Thiessen polygons, 
each of the areas having a separate value. Can anyone advise me about
how to carry out this (I suppose(~hope) simple) job? 

Thanks
