Classes to compute distance metrics between geometries.

Classes

DiscreteFrechetDistance

The Fréchet distance is a measure of similarity between curves. Thus, it can be used like the Hausdorff distance.

An analogy for the Fréchet distance taken from Computing Discrete Fréchet Distance:

A man is walking a dog on a leash: the man can move
on one curve, the dog on the other; both may vary their
speed, but backtracking is not allowed.

DiscreteHausdorffDistance

An algorithm for computing a distance metric which is an approximation to the Hausdorff Distance based on a discretization of the input Geometry.

DiscreteHausdorffDistance.MaxDensifiedByFractionDistanceFilter

A coordinate filter that computes the maximum PointPairDistance between points of an assigned Geometry and all filtered geometries. The filtered geometries' line segments are

DiscreteHausdorffDistance.MaxPointDistanceFilter

A coordinate filter that computes the maximum PointPairDistance between points of an assigned Geometry and all filtered geometries.

DistanceToPoint

Computes the Euclidean distance (L2 metric) from a Coordinate to a Geometry.

PointPairDistance

Contains a pair of points and the distance between them.
