Class InteriorPointFinder

java.lang.Object
com.vividsolutions.jump.geom.InteriorPointFinder
public class InteriorPointFinder extends Object
Find a reasonable point at which to label a Geometry.

Algorithm is:

  • Find the intersections between the geometry and a line halfway down the envelope
  • Pick the midpoint of the largest intersection (the intersections will be lines and points)
