Hi all,
currently I am working with large dataset:
projection: 99 (Transverse Mercator)
zone: 0
north: 5776000
south: 5756000
west: 3558000
east: 3578000
nsres: 2.5
ewres: 2.5
rows: 8000
cols: 8000
I have imported a topo sheet and want to set ZERO to NULL.
r.null dies in the middle,
r.mapcalc dies, too, at 18%.
+++ killed by SIGKILL +++
The call was:
r.mapcalc tk25_2="if(tk25=0,null(),tk25)"
I was expecting that GRASS works with such "large" datasets...
Does anyone have an idea where to search for the bug?
BTW:
r.mapcalc tk25_2="if(tk25=0,2,tk25)"
runs o.k. So the bug must be in NULL stuff of GRASS library.
Thanks for any advice
Markus
