How to prepare for the GDA2020

Since 1994 Australia has moved 1.8 metres due to plate tectonic motion. The GDA2020 is the latest set of coordinates available for organisations to use that provides closer alignment to the Global Navigation Satellite System (eg. GPS). We welcome Director of National Geodesy at Geoscience Australia, Nick Brown to break down what is GDA2020, how will it effect us and what we need to know to be prepared for the changes.
