Hi Ian! Thanks, it worked. But there is one problem. The unchanged objects has (x,y) coordinates and I’m getting (x,y,n/a) coordinates for the changed object. ArcGis does not seem to be able to have this(x,y,z) coordinates or mixed coordinate types. The changed objects has the correct values of x,y but does not show in ArcGis. Does anyone have any suggestions? Kind regards, Paul

Something like: DouglasPeuckerSimplifier simplifier = new DouglasPeuckerSimplifier(in); simplifier.setDistanceTolerance(tolerance); Geometry out = simplifier.getResultGeometry(); would do it. JTS also provides a TopologyPresersevingSimplifier and a LineSegmentSimplifier that would also handle your case.

I have polygons almost like a rectangle/romb. 90 percent has only five vertices, but some have more. The extra vertices is om the sides (the straight lines). I would like to remove those vertices and thought that there perhaps is a method using a max angle to find the extra vertices.
