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:
  GeoAPI 1.0
