    ATRF 2014
    GDA2020 coordinates are equivalent to ATRF2014@2020.0. ATRF2014 coordinates can be determined by application of the Australian Plate Motion Model. For general and technical information on GDA2020 see http://www.icsm.gov.au/gda2020 and ATRF2014 see http://www.icsm.gov.au/australian-terrestrial-reference-frame.
