[GRASS-user] problem using r.watershed

[Filipe Silva Dias]

Dear all

I'm trying to run r.watershed on a ASTER DEM (with the size of Portugal)
but I'm getting this error:

r.watershed elevation=DemPt at ETRS89 stream=stream
threshold=10000
SECTION 1a (of 5): Initiating Memory.
ERROR: G_malloc: unable to allocate 1515173064 bytes at init_vars.c:134
Subprocess failed with exit code 1
category information for [stream] in [ETRS89] missing or invalid

What am I doing wrong?

Thanks
Best
