Ellipsoidal 3D CS. Axes: latitude, longitude, ellipsoidal height. Orientations: north, east, up. UoM: degree, degree, metre.
Horizontal coordinates referenced to this CS are in degrees. Any degree representation (e.g. DMSH, decimal, etc.) may be used but that used must be declared for the user. Used in geographic 3D coordinate reference systems.

Described as a=6378388 m. and b=6356909 m. from which 1/f derived to be 296.95926... The figure was adopted as the International ellipsoid in 1924 but with 1/f taken as 297 exactly from which b is derved as 6356911.946 m.
