java.lang.Object

org.locationtech.jts.algorithm.InteriorPointLine

public class InteriorPointLine
extends java.lang.Object

Computes a point in the interior of an linear geometry.

Algorithm

• Find an interior vertex which is closest to the centroid of the linestring.
• If there is no interior vertex, find the endpoint which is closest to the centroid.

Method Detail

getInteriorPoint

public Coordinate getInteriorPoint()

addInterior

private void addInterior(Geometry geom)

Tests the interior vertices (if any) defined by a linear Geometry for the best inside point. If a Geometry is not of dimension 1 it is not tested.

Parameters:

geom - the geometry to add

addInterior

private void addInterior(Coordinate[] pts)

addEndpoints

private void addEndpoints(Geometry geom)

Tests the endpoint vertices defined by a linear Geometry for the best inside point. If a Geometry is not of dimension 1 it is not tested.

Parameters:

geom - the geometry to add

addEndpoints

private void addEndpoints(Coordinate[] pts)

add

private void add(Coordinate point)
