Interface GeocentricCRS

All Superinterfaces:

CoordinateReferenceSystem, GeodeticCRS, IdentifiedObject, ReferenceSystem, SingleCRS

@UML(identifier="SC_GeocentricCRS",
     specification=ISO_19111)
public interface GeocentricCRS
extends GeodeticCRS

A 3D coordinate reference system with the origin at the approximate centre of mass of the earth. A geocentric CRS deals with the earth's curvature by taking a 3D spatial view, which obviates the need to model the earth's curvature.

Used with CS type(s)
Cartesian, Spherical

Since:

1.0

Departure from OGC/ISO specification:
This interface is kept conformant with the specification published in 2003. The 2007 revision of ISO 19111 removed the GeographicCRS and GeocentricCRS types, handling both using the GeodeticCRS parent type. GeoAPI keeps them since the distinction between those two types is in wide use.
