Dear Moritz:
I wish to express my gratitude for your valuable advice. Thank you.
It succeeded when having tried as follows:
0 thru 100=1 0-100m
100 thru 200=2 100-200m
200 thru 300=3 200-300m
300 thru 400=4 300-400m
....
end
save as alt_class.txt
r.reclass input=old_rast_map output=new_rast_map < alt_class.txt
r.stats new_rast_map -c
Note that you could have also done something similar with
r.report map=old_rast_map units=k nsteps=
playing around with nsteps to get the same ranges. But r.reclass +
r.stats/r.report gives you more precise control of your classes.
Moritz
