================================================================================
.. versionadded:: 5.0.0
Convert geodetic coordinates to cartesian coordinates (in the forward path).

| **Domain** | 3D |
+---------------------+--------------------------------------------------------+
| **Input type** | Geodetic coordinates |
+---------------------+--------------------------------------------------------+
| **Output type** | Geocentric cartesian coordinates |
+---------------------+--------------------------------------------------------+
This conversion converts geodetic coordinate values (longitude, latitude,
elevation above ellipsoid) to their geocentric (X, Y, Z) representation, where
the first axis (X) points from the Earth centre to the point of longitude=0,
latitude=0, the second axis (Y) points from the Earth centrer to the point of
longitude=90, latitude=0 and the third axis (Z) points to the North pole.
