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.
zip codes for my region and I want to calculate average elevation of
each zip code).

Greetings
I have a vectorial data that divides my region in sub-areas. I
want to calculate the average value of a raster but instead
for all pixel values, I want to calculate the average of pixel
values that are inside each polygonIs this possible in GRASS?
If yes, how?
Thank you
Luis
