Interface GeocentricCRS

All Superinterfaces:

CoordinateReferenceSystem, IdentifiedObject, ReferenceSystem, SingleCRS

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

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

GeoAPI 1.0
