v.to.rast

[Walter Winant]

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.

> 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
