#962: GEOSNode is much slower that GEOSUnaryUnion ------------------------+--------------------------- Reporter: komzpa | Owner: geos-devel@… Type: defect | Status: new Priority: major | Milestone: Component: Default | Version: 3.6.2 Severity: Unassigned | Resolution: Keywords: | ------------------------+---------------------------
Comment (by mdavis): It is the case that JTS provides the [https://github.com/locationtech/jts/blob/master/modules/core/src/main/java/org/locationtech/jts/noding/snapround/GeometryNoder.java GeometryNoder] which uses snap-rounding. That would probably be reasonably fast and should not have the noding failures (at the price of having to round all coordinates slightly). The upcoming OverlayNG should also have this same behaviour and performance. So that will be a medium- term fix for this. It will be a task to revisit the GEOS noding and make it utilize the new code. -- Ticket URL: <https://trac.osgeo.org/geos/ticket/962#comment:3> GEOS <http://trac.osgeo.org/geos> GEOS (Geometry Engine - Open Source) is a C++ port of the Java Topology Suite (JTS).
