Hi there,
maybe a r.mapcalc/NULL FAQ, but I don't get it...
Assume you have a streams map (streams contain values,
other cells=NULL).
Now I want to add some values *everywhere* using r.mapcalc, but
it is only added in those cells not containing a NULL value.
Any ideas how to overcome this problem?
Thanks in advance
Markus
