Dear all,
I have a cover map (in raster format), and a vector map with a lot of
regions.
Now I need to quantify the amount of each cover class from my raster map
for each region
of my vector map.
v.rast.stats - Calculates univariate statistics from a GRASS raster map
based on vector polygons and uploads statistics to new attribute columns ?
It's a script and can be a bit slow.
It would be great to make this into a C-module one day, maybe by
integrating starspan ? See Jonathan call for help quite a while ago:

Obviously, you can also use starspan directly [1].
