Interface GeocentricCRS

All Superinterfaces:

CoordinateReferenceSystem, Info, ReferenceSystem

public interface GeocentricCRS

extends CoordinateReferenceSystem

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)
