Geoid velocity added

To correct for the vertical drift between reference frames, the velocity of the geoid height (VN) is now calculated and incorporated into the calculation of the orthometric height. View documentation to learn more.

The CGVD2013 height reported in the Vertical Data table is approximate because it is calculated from historical levelling data and not from the combination of GNSS and a geoid model.
