I think your problem may be that many of the polygons are not closed. If
you go into v.digit you can edit the polygons to close them. I am short on
details but I hope this helps.

> Hello all!
> I have a fairly large vector file containing field boundaries in a
> specific county. I am currently trying to convert this vector
> file to a raster using v.to.rast. I do the following:
> g.region vect=flds.vector res=1
> v.to.rast input=flds.vector output=flds.vector.out
> After conversion, however, the resulting raster file is *mostly*
> empty. With only certain fields in color (and the rest white).
> I've *checked* the attributes file of the vector map and it
> contains some 902 entries, but when I do a v.stats on my fields
> layer, I get:
> | Format: Version 4.0 (Level 2 access) (Portable)
> | Number of Lines: 2775
> | Number of Nodes: 1865
> | Number of Areas: 916 (incomplete)
> | Number of Isles: 23 (incomplete)
> | Number of Atts : 896
> I've tried running v.support, but I can't seem to get that
> "(incomplete)" notice

> *Any* help is appreciated. Thanks in advance.
