Hi Jörg,
I did some research:
the query
select st_astext (ST_CollectionExtract ('POINT (0 0)', 3));
returns "Polygon empty"
select st_astext (ST_CollectionExtract ('POINT (0 0)', 2))
returns "Empty String Line"
select st_astext (ST_CollectionExtract ('POINT (0 0)', 1))
returns "POINT (0,0)So far so good However, the query's select ST_AsText (geom), ST_CollectionExtract (geom, 1) select ST_AsText (geom), ST_CollectionExtract (geom, 2) select ST_AsText (geom), ST_CollectionExtract (geom, 3) returns all the same results "POINT (137237.8268 431571.3851)" "LINE STRING (136944.606800001 431208.568799999,136987.418099999 431205.513900001)" "POLYGON ((138960.872299999 438028.947000001,138954.046100002 438015.9692,138951.5854 438017.2392,138953.609499998 438022.398600001,138962.5392 438042.0042,138973.612100001 438066.173999999,138977.8189 438064.507100001,138970.0799 438048.711399999,138960.872 (...)" Any of this rings a bell perhaps? -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Mapserver-shows-all-nodes-on-a-GeometryCollection-tp5135064p5138520.html Sent from the Mapserver - User mailing list archive at Nabble.com. _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
