Hello.
I have two LineString depth contours that I want to check for crossing. For
this domain, overlap/touch is fine, but not crossing.
The following junit-formatted example show two LineStrings that touch each
other in (2 2). This is reported as a crossing by
LineString#crosses(LineString), but for my domain this is not a cross.
public void testCrosses() throws ParseException {
WKTReader r = new WKTReader();
LineString ls1 = (LineString) r.read("LINESTRING (1 2, 3 2)");
LineString ls2 = (LineString) r.read("LINESTRING (1 1, 2 2, 3 1)");
assertFalse(ls1.crosses(ls2));
}
Any tips to how I can check for crossing, but not touches like this?
Regards,
Tore Halset.
