geodetic2geocentric

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

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
