java.lang.Objectcom.vividsolutions.jts.operation.overlay.snap.GeometrySnapper
public class GeometrySnapper
Snaps the vertices and segments of a Geometry
to another Geometry's vertices.
Improves robustness for overlay operations, by eliminating
nearly parallel edges (which cause problems during noding and intersection calculation).
