Hi,
I have detected that LineStringSnapper, in the method with the
responsability of crack segments, snapSegments(CoordinateList, Coordinate[])
introduces an undesired (at least for me) effect.
A simple test case:
LINESTRING -> 100 100, 200 200
POINT -> 150.01 149.999
RESULT OF CRACKING-->100 100, 50.01 49.999, 200 200
In a perfect world, Id like to get a cracked linestring 100 100, 150 150,
200 200
I think we could improve this by adding three lines of code to snapSegments
method. These lines looks for the closest point of the segment to snap to
the crack point:
int index = findSegmentIndexToSnap(snapPt, srcCoords);
if (index >= 0) {
LinearSegment segment = new LinearSegment();
segment.p0 = srcCoords.getCoordinate(index);
segment.p1 = srcCoords.getCoordinate(index +1);
Coordinate newCoordinate =
seg.closestPoint(snapPt);
srcCoords.add(index + 1, newCoordinate, false);
}// if
Best regards.
