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 .
