The JTS Topology Suite is a Java library for creating and manipulating vector geometry.
OverlayNGSnapIfNeeded starts with FLOAT, backs off to 5 iterations of SnappingNoder, but lacks the final step of using the SnapRoundingNoder implementation.

The test of GEOS 350 in the TestOverlay-geos-350.xml file is an areaoverlay test. But GEOS has a test that actually includes the resultant. And the resultant is basically a line....
Running the existing XML tests using SnapIfNecessary (aka, making OverlayNG the default overlay implementation) and this case is an interesting failure. ``` Description: GC - shows handling linear rings and...
Using Snap-Rounding for noding in Overlay should provide full robustness. TopologyExceptions will never be thrown! **Design Aspects** - For now, the original Overlay algorithm is provided as the default behaviour...
