How to delete small closed lines, problems with v.edit and v.generalize (BLANDENIER Lucien) ---------------------------------------------------------------------- Message: 1 Date: Mon, 21 Oct 2013 14:48:21 +0000 From: BLANDENIER Lucien <[email protected]> To: "[email protected]" <[email protected]> Subject: [GRASS-user] How to delete small closed lines, problems with v.edit and v.generalize Message-ID: <[email protected]> Content-Type: text/plain; charset="iso-8859-1" Hello, I'm trying to simplify a contour map I've done with r.contour. I want to remove small area but when I use the command v.edit map=<map> tool=delete thresh=1000 query=length, only "non-closed map" are considered and the "closed line" (there are really lines, not polygons) remain. did you try to transform your line vector into a polygon vector and use after a v.clean command with tool=rmarea ? So only the small area will be removed and after you can again transform your polygon vector into a lin vector Mick I've the same problem with the command v.generalize. Does someone knows how to consider all the lines ? Attached is my shp. Regards Lucien -------------- next part -------------- A non-text attachment was scrubbed...
