In relation to r.categorize, is there a "quick" way to extract as separate
(new) raster maps each of the desired categories?
For instance, I want to extract from an SRTM3 subset (with min=0 and max
2365) 100m "wide" elevation zones. How can I make a script for this... ?
Where can I read more stuff in order to learn scripting... (!).
Thank you in advance!
I used the following command(s) to fo my job the hard way:
r.mapcalc SRTM3_0to100="if(((SRTM3 >= 0) && (SRTM3 <=100)),100,null())"
r.mapcalc SRTM3_100to200="if(((SRTM3 > 100) && (SRTM3
<=200)),200,null())"
r.mapcalc SRTM3_200to300="if(((SRTM3 > 200) && (SRTM3
<=300)),300,null())"
r.mapcalc SRTM3_300to400="if(((SRTM3 > 300) && (SRTM3
<=400)),400,null())"
r.mapcalc SRTM3_400to500="if(((SRTM3 > 400) && (SRTM3
<=500)),500,null())"
r.mapcalc SRTM3_500to600="if(((SRTM3 > 500) && (SRTM3
<=600)),600,null())"
r.mapcalc SRTM3_600to700="if(((SRTM3 > 600) && (SRTM3
<=700)),700,null())"
r.mapcalc SRTM3_700to800="if(((SRTM3 > 700) && (SRTM3
<=800)),800,null())"
...
