Polygonizer.getGeometry() results are non-deterministic when extractOnlyPolygonal=true

5

Polygonizer implementation seems to hold some internal state that affects the output of the getGeometry() method when extractOnlyPolygonal=true. The attached unit test class demonstrates the issue. Because of the nature...

Add new CoverageEdgeExtractor class to extract unique edges from a polygonal coverage

4

Since CoverageValidator will only return the invalid edges of a coverage, it would be very convenient to be able to extract the valid edges of a coverage. This is what...

Fixes https://github.com/locationtech/jts/issues/733 Please note that we must specify `outputDimension = 4` when writing geometries with M dimension, even when the geometry is XYM instead of XYZM. This behavior is the...

Two empty geometries should have the same topology

8

For example: ``` MultiPoint a = (MultiPoint) readerXY.read("MULTIPOINT EMPTY"); MultiPoint b = (MultiPoint) readerXY.read("MULTIPOINT EMPTY"); // This currently fails assertTrue(a.equalsTopo(b)); ``` Does the current behavior make sense?
