I have a raster 2mx2m with height values for forest canopy and a polygon layer stratifying the type of stand.
I would like to calculate the average height value for each polygon and wright the value in the attribute table of the polygon.
I tried zonal statistics - spatial analyst and zonal statistics as table and the computer crashed.
