The issue was that the contours vector was 3d. Now i could put the centroids
and add the area within the boundaries.
I am struck at how to associate the area (cat|area) with the associated
isohyetal lines? Any idea.
Thanks

Thanks.
I am using the first method that you suggested. But it fails to create
centroids whereas there are multiple isohyetal strips now and each should
have been given the centroid. To give you the details on what i did.
In real scenario, we will have the defined catchment area (which will be

1. I saw the details of the raster created from v.surf.rst

Hi Micha,
I could create isohyetal lines using the suggested steps:
-v.in.ascii
v.in.ascii x=2 y=1 cat=0 input=01_08nov2001 out=rainvector columns=x
double precision, y double precision, rain_info double precision --o
fs=\t skip=1
- set the region to smaller vector and set the mask created

I was wrongly using the term region in my question above. The requirement
is slightly different. Let me explain you in detail.

I am new to GRASS and the basic concepts of this field. Below, I tried my

This is perfect, thanks !

These white spots in the voronoi vector may be the cause. But i ran the
voronoi module on the archsites vector of the Spearfish60 dataset and its
runs fine. The cmd was
v.voronoi input=archsites output=arch_voronoi
The only difference is that the region of archsites has got less points

The problem that we are facing may be related to above issue.
