geodetic2geocentric

typhon.geodesy.geodetic2geocentric(h, lat, lon, ellipsoid=None, **kwargs)

Convert from geodetic to geocentric coordinates.

The geodetic coordinates refer to the reference ellipsoid specified by input ellipsoid. See module docstring for a defintion of the geocentric coordinate system.

Parameters:

• h – Geodetic height (height above the reference ellipsoid).

• lat – Geodetic latitude.

• lon – Geodetic longitude.

• kwargs – Additional keyword arguments for cart2geocentric().

• ellipsoid – A tuple with the form (semimajor axis, eccentricity). Default is ‘WGS84’ from ellipsoidmodels.

Returns:

Radius, geocentric latiude, geocentric longitude

Return type:

tuple
