[GRASS-user] Large vector files

I wanted to get some feedback on how well GRASS works with very large vector
files (> 2gb) -- I have a 64 bit mac that I have grass running on now, so
I'm hoping the 64 bit memory system will work -- thoughts?

Hi Jonathan,

did you enable large file support ?

Hmm, I am using the binaries from
http://www.kyngchaos.com/software/unixport/grass/ --> assuming LFS was
enabled (I can always recompile if I need to), are there large file issues
with *vectors* I need to worry about? The raster LFS is fine, mind you --
I'm very happy with that. I'm just a bit fed up with ArcMap's 2gb
limitation on file sizes, and I'm wondering if GRASS has ESRI beat in vector
LFS along with the raster LFS...

Good point. I am not entirely sure. I do know that there can be problems with
the topology library when files get extremely large: see past messages about
lidar data and r.in.xyz .

Hamish might have some good input on this....

Cheers,

Dylan
