ellipsoid_r_geocentric

typhon.geodesy.ellipsoid_r_geocentric(ellipsoid, lat)

Geocentric radius of a reference ellipsoid.

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

Note

To obtain the radii for geodetic latitude, use ellipsoid_r_geodetic().

Parameters:

• ellipsoid (tuple) – Model ellipsoid as returned by ellipsoidmodels.

• lat (float or ndarray) – Geocentric latitudes.

Returns:

Radii.

Return type:

float or ndarray
