Hi, any reason why 'v.clean tool=rmline' doesn't respect thresh= to remove small lines? (like rmarea) Or is it just a matter of writing the code? http://trac.osgeo.org/grass/changeset/24404 workaround: v.db.addcol column='DOUBLE length' v.to.db option=length column=length v.extract where='length > $thresh' thanks, Hamish
