I'm looking for the easiest way to compute spatial average
cell values for a raster map (such a DEM or a rainfall field)
and to create a new raster map when the surfaces are defined
by the areas of a vector file.
1. Label the areas of your vector map using v.digit.
2. Use v.to.rast to convert the map into a raster.
3. Use r.average to do your job.
