Interface EllipsoidalCS

All Superinterfaces:

CoordinateSystem, IdentifiedObject

@UML(identifier="EllipsoidalCS",
     specification=ISO_19111)
public interface EllipsoidalCS
extends CoordinateSystem

A 2- or 3-dimensional coordinate system for use with geodetic CRS. Position is specified by geodetic latitude, geodetic longitude, and (in the 3D case) ellipsoidal height.

This type of CS can be used by coordinate reference systems of type GeographicCRS, potentially in combination with DerivedCRS. The following examples describe some possible set of axes for ellipsoidal CS used with the above-cited CRS:

Example 1: used with a two-dimensional Geographic CRS

Axis name	Abbr.	Direction	Unit
Geodetic latitude	φ	AxisDirection.NORTH	degree
Geodetic longitude	λ	AxisDirection.EAST	degree

Example 2: used with a three-dimensional Geographic CRS

Axis name	Abbr.	Direction	Unit
Geodetic latitude	φ	AxisDirection.NORTH	degree
Geodetic longitude	λ	AxisDirection.EAST	degree
Ellipsoidal height	h	AxisDirection.UP	metre
