Class IndexedPointInAreaLocator

Determines the Location of Coordinates relative to an areal geometry, using indexing for efficiency. This algorithm is suitable for use in cases where many points will be tested against a given area.

The Location is computed precisely, th that points located on the geometry boundary or segments will return Boundary.

IPolygonal and LinearRing geometries are supported.

The index is lazy-loaded, which allows creating instances even if they are not used.

Thread-safe and immutable.
