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).

Yes. But they

Which makes me assume this is a bug since the vectors are clean.
Where do I get those datasets?

Yes it is reproducible with spearfish:

It may be a size dependent bug. Small vectors, v.buffer works. Large vectors it
does not.

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

Hi Wesley :-)
A (silly) suggestion: load in QGIS and then use save as shapefile... :-?
Maybe it'll work without errors :-)

Hi all,
Does anybody have a suggestion for subtracting the elements in one
line vector from another line vector?

Is there any way to create a Weighted Voronoi Diagram in grass?
v.voronoi.* will create ordinary ones, but not weighted.

Dear all,
I am trying run a r.watershed command with one 7200x7200 DEM map.
But after one day running, the system crash without finish the output
generation.
Please, see below (2 warnings before crash).
By the way I am running grass 6.4.0 SVN (rc4?) under Msys/Vista
on a 6Gb/64 bits machine.
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.
Hi Stephen,
Thanks for your reply.
I thank the disk space is not problem because I still have 100Gb free.
What was the dimension (row and columns) that you got success?!
May be 7200x7200 is to large. (?)
Cheers

Do you have enough hard disk
I will look tomorrow, but I think it was about 1000x1000.
