[GRASS-user] v.buffer segmentation fault
Dear grass developers, I have a potential bug here, if everything I do is right. I have a vector calledn england. I run v.buffer input=england output=england_buffer type=area buffer=1420 and all I get is segmentation fault. P.S.: I cannot login anymore into the tracker with my ID (ct529). Can Martin do anything about it?

Positive reproducibility with spearfish - Re: [GRASS-user] v.buffer segmentation fault
Yes it is reproducible with spearfish: v.buffer input=landcover output=lcb distance=2 --overwrite Buffering lines... 100% Buffering areas... Segmentation fault GRASS 6.4.0RC4 (Spearfish60):~ It may be a size dependent bug. Small vectors, v.buffer works. Large vectors it does not.

[GRASS-user] Export of large vector grid
Dear Grass users, I am trying to export a large vector to the shapefile format. The vector is in the form of a grid which I want to use to sample satellite data, it has 354 columns and 388 rows (in the form of a grid, each cell being 30 m by 30 m). I am working on windows and have been trying to export the vector file as a shapefile, the export takes a really long time and actually just hangs after a while. This is the command I am using in Grass 6.4.0svn (2009) v.out.ogr -c input=g...@wes type=area 'dsn=D:\wes2006\Projects\Tree Cover\LQ-upscaling\30m_New_Analysis' olayer=TEST_GRID layer=1 format=ESRI_Shapefile I am pretty sure all is well but cant understand why the vector fails to export. Is it possible to use another format, or is shapefile the best to use? Many thanks and kind regards, Wesley Wesley Roberts MSc.

[GRASS-user] Help needed with exporting GRASS 6.4.0 vector files
All: I have GRASS 6.4.0 vector maps (polygons) that I have digitized, which I need to export to ASCII with both attributes and (lat-long) boundary vertices. I need to subsequently reformat the data to a some non-standard ascii format. How do I do this? I can use db.select to easily get the attribute data; I can also use v.out.ascii to do this. I can also use v.out.ascii with format=standard to get the lat-long pairs. Of course the problem is getting the attribute data reliably associated with the lat-long pair data. It's not a problem for me to write a script to reformat the ascii data into the format I need, I'm just wondering how to best get the data in *some* ascii format that I can reliably deal with.

Do you have enough hard disk space? I have had a problem running r.watershed on very large datasets (my computer is much more modest). I have had luck resampling the data to a larger resolution and then running r.watershed. r.watershed crashes at 10m res but will run just fine at 50m. 1GB RAM.
