Detailed Description

Determines the location of Coordinates relative to an areal geometry, using indexing for efficiency.

The Location is computed precisely, in that points located on the geometry boundary or segments will return geom::Location::BOUNDARY.

Polygonal and LinearRing geometries are supported.

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