Yes. Although I think the original post was asking to get the raster
values into an existing vector. IIUC r.statistics would require
converting the vector to a raster, then back to a vector. Or am I

Hi all
I'm reading the v.rast.stats Help and I'm a bit confused. It says "Calculates basic
univariate statistics from a raster map only for the parts covered by the specified vector
map". But for >>instance if all my region is covered by different polygons and, if I
want to calculate for each polygon my average value from raster, is this function helpful?
(e.g. I have vector with
yes, exactly the function you need. It adds nine attribute columns to your
vector layer with min,max,mean, etc values calculated from the raster.
