# ellipsoid_r_geodetic¶

typhon.geodesy.ellipsoid_r_geodetic(ellipsoid, lat)[source]

Geodetic radius of a reference ellipsoid.

Gives the distance from the Earth’s centre and the reference ellipsoid as a function of geodetic latitude.

Note

To obtain the radii for geocentric latitude, use ellipsoid_r_geocentric().

Parameters: ellipsoid (tuple) – Model ellipsoid as returned by ellipsoidmodels. lat (float or ndarray) – Geodetic latitudes. Radii. float or ndarray
