Hi Bertram, Sounds like you may have invalid topologies. Whenever I have hit "side location conflict" that has been the case.
Have you tried calling buffer(0) on those geometries to try and clean them up, prior to your union or intersection attempts? If not, try it, it may help. regards, -Frank On Wed, Feb 27, 2008 at 7:47 AM, Bertram Klein <[EMAIL PROTECTED]> wrote: > > Hello, > > I have several problems while unioning or intersection two "big" polygons / > surfaces (gml to big to post). > > Some Geometries throw exceptions like this: > 1. side location conflict [ (3536703.50390625, 6002840.29296875, NaN) ] > 2. no outgoing dirEdge found [ (3633716.5743942726, 6007299.683068088, NaN) > ] > 3. found null Directed Edge > > Normaly I use jts 1.7. > I try jts 1.8 and 1.9 but it have no positiv effects. > > Here an example of the StackTrace: > com.vividsolutions.jts.geom.TopologyException: side location conflict [ > (3592023.1542986925, 6004173.399640237, NaN) ] > at > com.vividsolutions.jts.geomgraph.EdgeEndStar.propagateSideLabels(EdgeEndStar.java:297) > at > com.vividsolutions.jts.geomgraph.EdgeEndStar.computeLabelling(EdgeEndStar.java:135) > at > com.vividsolutions.jts.geomgraph.DirectedEdgeStar.computeLabelling(DirectedEdgeStar.java:127) > at > com.vividsolutions.jts.operation.overlay.OverlayOp.computeLabelling(OverlayOp.java:364) > at > com.vividsolutions.jts.operation.overlay.OverlayOp.computeOverlay(OverlayOp.java:165) > at > com.vividsolutions.jts.operation.overlay.OverlayOp.getResultGeometry(OverlayOp.java:127) > at > com.vividsolutions.jts.operation.overlay.OverlayOp.overlayOp(OverlayOp.java:66) > at com.vividsolutions.jts.geom.Geometry.union(Geometry.java:1067) > at > org.deegree.model.spatialschema.GeometryImpl.union(GeometryImpl.java:305) > > What can I do now? > > Bertram > _______________________________________________ > jts-devel mailing list > [email protected] > http://lists.refractions.net/mailman/listinfo/jts-devel > > -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Frank Hardisty [EMAIL PROTECTED] GeoVISTA Center 206 Walker Building Dutton e-Education Institute 434 Earth and Engineering Sciences Building 814-867-1471 http://www.geovista.psu.edu/grants/cdcesda/software/ _______________________________________________ jts-devel mailing list [email protected] http://lists.refractions.net/mailman/listinfo/jts-devel
