Class VertexHausdorffDistance

java.lang.Object
com.vividsolutions.jump.algorithm.VertexHausdorffDistance
public class VertexHausdorffDistance extends Object
Implements algorithm for computing a distance metric which can be thought of as the "Vertex Hausdorff Distance". This is the Hausdorff distance restricted to vertices for one of the geometries. Also computes two points of the Geometries which are separated by the computed distance.

NOTE: This algorithm does NOT compute the full Hausdorff distance correctly, but an approximation that is correct for a large subset of useful cases. One important part of this subset is Linestrings that are roughly parallel to each other, and roughly equal in length - just what is needed for line matching.
