047 * A geocentric CRS deals with the earth's curvature by taking a 3D spatial view, which obviates

058 * This interface is kept conformant with the specification published in 2003.
059 * The 2007 revision of ISO 19111 removed the <code>GeographicCRS</code> and
060 * <code>GeocentricCRS</code> types, handling both using the <code>GeodeticCRS</code> parent type.
061 * GeoAPI keeps them since the distinction between those two types is in wide use.
