Hi, You might want to look at ST_NPoints and ST_Numpoints for linestrings : http://postgis.refractions.net/documentation/manual-1.4/ST_NumPoints.html http://postgis.refractions.net/documentation/manual-1.4/ST_NPoints.html However for geometries in general it's more complicated. -- Maxime _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users
