geodetic2cart

typhon.geodesy.geodetic2cart(h, lat, lon, ellipsoid=None)

Convert from geodetic to geocentric cartesian 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.

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

Returns:

x, y, z coordinates.

Return type:

tuple
