[GRASS-user] resampling and patching DEM

[Silvia Simoni]

Hi,

I need to patch dems with different resolutions (1x1m) and (2x2 m) and  
resample them to a coarser resolution (10x10 m). Which is the correct  
procedure?

a. resampling the 1x1 dem to 2x2 using r.resampl.stats -w (to be more  
accurate)
patch them all at 2x2, resample the patched dem to 10x10m;

b.resample the 1x1 and 2x2 dem to 10x10 m separately using  
r.resampl.stats -w, and then patch them all.

thanks

silvia
