I must do something wrong or there is a bug in JTS:
I have a point that falls with a segment 100%, it does not overlap any segment
vertice.
//Sample points that cause failure
//point.getGeometry().toText(): POINT (1189813.2298558373
1282137.5104076413)//line.getGeometry().toText(): LINESTRING
(1190117.3577566557 1282021.6521597095, 1189478.994760329 1282264.8380630743)
//point.getGeometry().toText(): POINT (1189518.6390980254
1282448.001756093)//line.getGeometry().toText(): LINESTRING (1189426.304481268
1282287.1301042158, 1189622.879753152 1282629.6169181187)
Java code:
Coordinate pointCoord = point.getGeometry().getCoordinate();Coordinate[]
lineCoords = line.getGeometry().getCoordinates();
Any of the following if-s evaluate their condition to false, when I expected
true:
LineSegment lineSegment = new LineSegment(lineCoords[0], lineCoords[1]);if
(lineSegment.distance(pointCoord) == 0) {
if (CGAlgorithms.distancePointLine(pointCoord, lineCoords[0], lineCoords[1]) ==
0) {
if (CGAlgorithms.isOnLine(pointCoord, lineCoords)) {
Any help, please? I consider all those 3 methods would be appropriate for
determining if point within segment.
thank you.
