To bring Australia’s coordinates in line with those from global satellite positioning systems, Australia will soon be changing to a new official national datum called the Geocentric Datum of Australia 2020 or GDA2020.
Preparations by the South Australian Government are in full swing, with work being done to transition systems and processes to support GDA and the associated Map Grid, MGA 2020.
It is anticipated that South Australian Government geospatial datasets will be available in GDA2020 in the first quarter of 2019.
Stay tuned for 2019 when a list of agencies delivering GDA2020 data becomes available.
It is anticipated that GDA94 datasets will continue to be available for 12 months after the delivery of GDA2020.
