89 The reference ellipsoid for the Earth for which the WKT string is defined in 8.2.1 is an oblate ellipsoid of revolution. A triaxial ellipsoid (figure D.1) may be required for planetary mapping and other applications. Their full CRS description is outside the scope of this International Standard.
A WKT string definition for a triaxial ellipsoid is:
