Hi folks, I have a quick troubleshooting question. I'm trying to run r.watershed to extract stream segments and I'm receiving the following error;
GRASS 6.4.0RC5+39438 (ccarleton.minanha.utm):~ > r.watershed elevation=aster_srtm_dem_fil...@cloudremoval threshold=10 stream=aster_srtm_stream memory=300 SECTION 1a (of 5): Initiating Memory. SECTION 1b (of 5): Determining Offmap Flow. 100% SECTION 2: A * Search. 100% SECTION 3: Accumulating Surface Flow. 100% SECTION 4: Watershed determination. Segmentation fault WARNING: Subprocess failed with exit code 35584 WARNING: category information for [aster_srtm_stream] in [geophys] missing or invalid I haven't been able to find something in the mailing lists about this, but if you know of somewhere that I can find a solution I'd appreciate the link. I'm running GRASS 6.4 RC5 on Ubuntu LTS 10.04 with a Dell Precision T7500 Workstation. The region settings are as follows; projection: 1 (UTM) zone: 16 datum: wgs84 ellipsoid: wgs84 north: 1942292.77488498 south: 1798172.56898554 west: 174812.49733566 east: 382055.4579663 nsres: 15.00002143 ewres: 15.00021429 rows: 9608 cols: 13816 cells: 132744128 The actual DEM is much smaller than this (a composite ASTER/SRTM DEM) and I have 12GB of memory so I'd be surprised if this was a memory problem. Before I start working with GDB or other in-depth debugging I was hoping someone would have a short answer for this already. Thanks for your time, Chris
