Hi Jukka, I guess the lines are almost parallel of you zoom in : or parallel for the observer - but indeed are not. They could also be a duplicate. So, the option would be to change precision of evaluation, I believe or delete one or separate them? At least manual intervention seems necessary.
Perhaps not so useful but usually this was the case in the past :) Cheers, Stefan On Tue., May 18, 2021, 13:13 Rahkonen Jukka (MML), < jukka.rahko...@maanmittauslaitos.fi> wrote: > Hi, > > > > I tried to run the Overlay function for this heavy dataset > https://we.tl/t-gshlI4TbCU > > Both layers seem to have no topology errors but the Overlay function fails > with an error > > > > org.locationtech.jts.geom.TopologyException: found non-noded intersection > between LINESTRING ( 95.49610823093388 4.949137070569244, 95.49623518653348 > 4.948912456969601 ) and LINESTRING ( 95.4962351860291 4.948912457861983, > 95.49623518653348 4.948912456969593 ) [ (95.49623518627793, > 4.948912457421728, NaN) ] > > at > org.locationtech.jts.noding.FastNodingValidator.checkValid(FastNodingValidator.java:140) > > at > org.locationtech.jts.geomgraph.EdgeNodingValidator.checkValid(EdgeNodingValidator.java:81) > > at > org.locationtech.jts.geomgraph.EdgeNodingValidator.checkValid(EdgeNodingValidator.java:46) > > at > org.locationtech.jts.operation.overlay.OverlayOp.computeOverlay(OverlayOp.java:231) > > at > org.locationtech.jts.operation.overlay.OverlayOp.getResultGeometry(OverlayOp.java:183) > > at > org.locationtech.jts.operation.overlay.OverlayOp.overlayOp(OverlayOp.java:86) > > at > org.locationtech.jts.operation.overlay.snap.SnapIfNeededOverlayOp.getResultGeometry(SnapIfNeededOverlayOp.java:75) > > at > org.locationtech.jts.operation.overlay.snap.SnapIfNeededOverlayOp.overlayOp(SnapIfNeededOverlayOp.java:37) > > at > org.locationtech.jts.geom.GeometryOverlay.overlay(GeometryOverlay.java:76) > > at > org.locationtech.jts.geom.GeometryOverlay.union(GeometryOverlay.java:157) > > at > org.locationtech.jts.geom.Geometry.union(Geometry.java:1367) > > at > org.openjump.core.geomutils.algorithm.IntersectGeometries.nodeLines(IntersectGeometries.java:478) > > at > org.openjump.core.ui.plugin.tools.IntersectPolygonLayersPlugIn.runIntersectionNew(IntersectPolygonLayersPlugIn.java:205) > > at > org.openjump.core.ui.plugin.tools.IntersectPolygonLayersPlugIn.run(IntersectPolygonLayersPlugIn.java:127) > > at > com.vividsolutions.jump.workbench.ui.task.TaskMonitorManager$TaskWrapper.run(TaskMonitorManager.java:151) > > > > What does this error mean, in which part of the operation it happens, and > is there any way to get over it?
