public class ProjectedCoordinateReferenceSystem
extends SingleCoordinateReferenceSystem<C2D>

A projected CoordinateReferenceSystem.

A projected coordinate reference system is a coordinate reference system derived from a two-dimensional geographic coordinate reference system by applying a map projection and using a Cartesian coordinate system.
