Subject: r.rescale: -z flag wanted
r.rescale input=asp1 from=0,180 output=test_north to=1,1
r.rescale does not set cells outside the "from" range to 0 (described in the
help), but to NULL
(reported by timcera@earthlink.net)
Andreas Lange, 10/2000: This is IMHO not a bug, but a feature. All modules
should write NULL instead of 0 (zero) for missing values for patching
maps or display overlays.
But if the problem with r.reclass is solved i can add a "-z" flag that
switches this behaviour from writing NULL to writing "0" (zero).
