# Module datum

DEPRECATED, use module datums or ellipsoids instead.

Version: 21.12.29

Classes
| 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.
| Datum Ellipsoid and transform parameters for an earth model.
| Transform Helmert transformation.
