Re: [GRASS-user] how to calculate area of voronoi polygons considering the boundary of the catchment
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 Daljeet daljeet wrote: > > Thanks. > > I am using the first method that you suggested.

Re: [GRASS-user] clear sky index interpolation
Hi,
Are you trying to generate a 2D raster map of interpolated values, or
a 3D 'volume' of interpolated values? If your input consists of
{lat,lon,kc}, then a 2D raster map is likely what you are after. In
that case, check out the v.surf.rst module.
Cheers,
Dylan

Check g.region -p3 if rows and rows3 match and col and cols3. They need to be adjusted if not.
