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.
- 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.
