[GRASS-user] r.average issue with rasters at different resolutions

Hi Margherita,

Thank you for your reply!

Well, shouldn't be the base map just a raster map which assigns the same category to the cells that should be averaged together?

I'm sorry but I don't get the point. The base map I use is always at the same resolution (res=0.2), which is also the resolution of the region. My problem is that I have a cover map with with a different resolution (res=200) and if I use it as it is I get wrong result. The workaround I found is to change the resolution of the cover map before running r.average (r.mapcalc "rescaled_cover_map=original_cover_map") but it's ugly.

Maybe I'm missing something,
Thanks!
