ellipsoid_r_geodetic

typhon.geodesy.ellipsoid_r_geodetic(ellipsoid, lat)

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.

Returns:

Radii.

Return type:

float or ndarray
