# Module datum

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

Version: 23.11.26

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.
