[GRASS5] [bug #1362] (grass) v.out.shape only can export labeled polygones

Subject: v.out.shape only can export labeled polygones

Platform: GNU/Linux/i386
grass obtained from: CVS
grass binary for platform: Compiled from Sources

I want to export digitized polygons from GRASS 5.0 wich are not labeled. The v.out.shape module is from the actual CVS. I always get the output" memory error". After making some tests with labeled and unlabeled polygons, I get the conclusion that this module can only export labeled polygons!

Would it be difficult to improve v.out.shape so that it can export
non labeled polygons from GRASS? The problem is that we have about
300 polygons in one layer and it would be very exhausting to label
all those polygons. Any suggestions?

Thanks,

If I remember it well, v.out.shape worked in that way, but some other
user :slight_smile: wanted export of labeled areas only, so it was changed.
We need new flag for that to do it optionaly.

But what about v.alabel?

Oh, this is a good hint. We tried it and it seems to work.

BTW: Could it be possible to indicate in the manual page of
v.out.shape that a labeling of all polygons is required and that
this could be done be v.alabel?

Thanks,

Some other user wanted it to work with polygons period. I set it to
only export labelled areas because it is the only way to differentiate
islands from holes. It would be possible to modify it to output all
areas.
