The JTS Topology Suite is a Java library for creating and manipulating vector geometry.
Buffering this closed line with distance = 70 produces a polygon with an incorrect hole artifact. If an endpoint is moved slightly to make the line non-closed, the buffer is...
(Not sure if this is a bug or just me using JTS in an unsupported way) The need: union ~5-20 polygons that may be (slightly) overlapping My current implementation uses...
Here attached is an awful geometry (a GPS track) making Polygonizer entering an infinite loop. I could not reduce the geometry to a simpler case. Just found that the infinite...
I use the jts 1.16 and sometimes will failed by contains method with this bug, failed org.locationtech.jts.geom.TopologyException: side location conflict [ (-26.908931699420773, 170.85541495764005, NaN) ] at org.locationtech.jts.geomgraph.EdgeEndStar.propagateSideLabels(EdgeEndStar.java:286) at org.locationtech.jts.geomgraph.EdgeEndStar.computeLabelling(EdgeEndStar.java:125) at...
In TopologyPreservingSimplifier.java, If I change type of linestringsMap from HashMap to TreeMap, the result for same input geometry will be different.
I noticed that `Geometry.equals` and `Geometry.equalsExact` return different results for empty geometries: ```java GeometryFactory gf = new GeometryFactory(); Geometry g0 = gf.createPoint(); Geometry g1 = gf.createPoint(); assertEquals(g0.equals(g1), g0.equalsExact(g1)); ``` This...
Using OverlayNG, the result of computing the intersection of two identical polygons has its vertices rotated by one from the inputs. It is desirable that the vertices be identical. (This...

Computing the buffer of a `Point` that has a `CoordinateSequence` with a dimension of 2 will result in a `Polygon` that has an exterior ring with a dimension of 3....
The `WKTReader` silently adds a dimension to 2D WKT when `isOldJtsCoordinateSyntaxAllowed = true`. This is the default. ```java Point pt = new WKTReader().read("POINT (10 10)"); if (pt.getCoordinateSequence().getDimension() == 3) System.out.println("dimension...
