On the Problem of Finding Intersection Points for Polylines #320

Open lxqaoliao opened 6 months ago

lxqaoliao commented 6 months ago

Why is the following code not a point but a line： SpatialReference s = SpatialReference.create(4450);

    Polyline lineA = new Polyline();
    lineA.startPath(new Point(352908.85 , 3422574.91));
    lineA.lineTo(new Point(352910.00, 3422580.00));

    Polyline lineB = new Polyline();
    lineB.startPath(new Point(352921.52 , 3422543.38));
    lineB.lineTo(new Point(352908.85 , 3422574.91));

    Geometry intersection = GeometryEngine.intersect(lineA, lineB, s);
    Geometry.Type type = intersection.getType();
    System.out.println();

@lxqaoliao Use OperatorIntersection instead https://github.com/Esri/geometry-api-java/blob/e237fc0fe4a7fb43583dd335d58e1f23ab18ac4b/src/main/java/com/esri/core/geometry/OperatorIntersection.java#L73 See similar issue https://github.com/Esri/geometry-api-java/issues/301
