done using the ITRF2014 to GDA2020 transformation which approximates plate motion in Australia. To complete
this transformation on another plate a different plate motion model should be used.
-Some careful math needs to be completed here. To go from 2007 to 2030, 23 years
-of plate motion needs to be added. The reference epoch of the ITRF2014 to GDA2020 transformation is 2020.
-As such 23 needs to be subtracted from 2020 to get the desired motion. This means the epoch 1/1/1993 should be entered.
+The plate_motion_transformation function can be used to move coordinates in time. This avoids the need to
+calculate the difference between the reference epoch and the epoch required. This can be seen below.
.. caution::
Transformations using the plate motion model of itrf2014_to_gda2020 should only be completed for epochs between
2005 - 2035. For transformations outside of this range refer to the :ref:`next ` section.
