[GRASS-user] How to create 500m DEM from 90m DEM

Dear Markus and all

Thank you for your useful advice.

r_resolution

I visited this site and checked 'finer', 'coarser' and 'sparse'.
My case is 'coarser' (90m -> 500m), so it should be used 'r.resamp.stats', I s
ee. 

Thanks

Best,
Yasuo shimada: Japan weather association
