Hi Nikos, Thank you for that suggestion. Indeed, I did NOT realize that v.extract was used to create new geometry in a layer. However, I too need some of the islands (is there a technical difference between island, hole, and missing polygon?).
There is a single missing polygon that I now have attribute data for and I want to create the polygon (from the existing points and lines) and fill-in the related attribute fields. I imagined some sort of interactive process of clicking on the relevant bounding elements and *presto* the polygon would jump into existence. I tried this in v.digit but was not able to get the desired result. This is a really basic step that people do several times a day, right? -david _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
