Coordinate System
A Coordinate System is the set of coordinate axes, with the implied metric of
the coordinate space. The Coordinate System is defined as one of a series
of alternative Coordinate System Types.
Datums
The specification of the origin, orientation, and scale of the associated
Coordinate Reference System and thus the reference used to measure
positions in a geocentric, geographic or projected CRS.
Ellipsoids
Reference Ellipsoid is an ellipsoid whose dimensions closely approach the
dimensions of the geoid. It is the approximation of the Earth's surface as a
squashed sphere.
Prime Meridians
The PrimeMeridian class is used as the reference for Longitude measurements.
Transformations
Specification of a coordinate transformation.
CRS
Definition of one Coordinate Reference System (CRS), including the system
identification and possibly its complete specification.
