Module datum

DEPRECATED on 2022.09.12, use module pygeodesy.datums or pygeodesy.ellipsoids instead.

Version: 24.06.15

Classes
	Datum Ellipsoid and transform parameters for an earth model.
	Transform Helmert datum transformation.
	Ellipsoid Ellipsoid with equatorial and polar radii, flattening, inverse flattening and other, often used, cached attributes, supporting oblate and prolate ellipsoidal and spherical earth models.
	Curvature2Tuple 2-Tuple `(meridional, prime_vertical)` of radii of curvature, both in `meter`, conventionally.
