Hello all,
I have rasters in a fine resolution, with values of 1 and null. I need
to create, in a coarser resolution, new rasters where each cell gets
the total number of non-null pixels from the fine resolution raster
that are within the coarse pixel.
The clunky method I worked out uses r.out.xyz and r.in.xyz. Starting
in the fine resolution, I export all (non-null) cell locations with
r.out.xyz. Then I switch to the coarse resolution and do r.in.xyz with
method=n. Seems to work, but is there anything better, more elegant?
Thanks,
Micha
