Class SimpleMinimumClearance

java.lang.Object

org.locationtech.jts.precision.SimpleMinimumClearance

public class SimpleMinimumClearance
extends Object

Computes the minimum clearance of a geometry or set of geometries.

The Minimum Clearance is a measure of what magnitude of perturbation of its vertices can be tolerated by a geometry before it becomes topologically invalid.

This class uses an inefficient O(N^2) scan. It is primarily for testing purposes.
