If you have a recent version of QGIS, just start editing and use the "Delete part" edit tool. -Mike On 23 September 2010 10:28, Andrea Peri 2007 <[email protected]> wrote: > Hi, > > I need to remove a single part from a multipart geometry. > > For example having a multipolygon with three part I need to remove one of > these parts so the result is a multipolygon with two parts. > > In postgis I find a function to extract a single part from a multipart ( > ST_GeometryN ) but don't find nothing to remove one. > > So the only method I know is re-create the geometry skipping the part > unwanted, but I hope to find somethink more simple. > > Thx, > > Andrea. > > _______________________________________________ > postgis-users mailing list > [email protected] > http://postgis.refractions.net/mailman/listinfo/postgis-users > _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
