Method: Geocentric translations (geog2D domain)
Remarks: Approximation at the 3m level assuming WGS 84 is equivalent to ITRF2014 within the accuracy of the transformation. See GDA2020 to WGS 84 (G1762) (1) (code 8448) for a better approximation and ITRF2014 to GDA2020 (1) (code 8049) for actual relationship.
