[GRASS-user] Re: Exporting Vector data to SHP (v.out.ogr)- takes a lot of time

[Luis Lisboa]

The problem is that, I left it this night processing and, when I
returned it has freezed. So, v.out.ogr is not being able to export
vector files produced by r.to.vect... As I said, maybe it's related
with some option in r.to.vect that is messing this up. Or something
related with tables.

Can anyone give me some tips on this?

Thanks

Luis
