Sorry if not clear enough:
"same amount in kilograms with finer and coarser resolution" meaning "same total amount with finer and coarser, suming over all grid cells".
>Dear GRASS users,
>My problem concerns a raster in lat-lon projection, having a given resolution of ewres1,nsres1. For every cell, the category value is >expressed in kilogram.
>I need to transform it into the same grid but with coarser resolution, say ewres2=10*ewres1 and nsres2=10*nsres1, BUT the >transformation need to be mass-conservative (so, I need to get exactly the same amount in kilograms with finer and coarser resolution).
>Can I do in a simple way with GRASS ?
