Hello Erik,
try this in r.mapcalc:
new_dem = if(old_dem < 25, null(), old_dem)
old_dem – name of map with input DEM;
null() – value to assign to cells below 25 (could be 0 too).
Keep in mind – your approach will put under water everything below a
specified level even if there is a natural or
Hi Erik,
IIUC, you would need something like the following:
r.mapcalc expression="bla = if(elev <= 25, 0.0, elev)"
