Developments towards GDA Modernisation

Users of position in Australia are fundamentally users of the existing definition of the national datum. Due to Australia sitting on the fastest moving continental tectonic plate on Earth, positions measured in the past quickly degrade over time. Coordinates measured relative to the Geocentric Datum of Australia 1994 are now over 1.5 metres in error. With the growing proliferation of location-based information readily available at our fingertips, the economic success of nations across the world are becoming increasingly dependent on the continuous supply of accurate, real-time position. It is thus clearly appropriate for leading professionals within the Surveying and Spatial Sciences Industry to ensure that the required level of accuracy needed by the community is available for their various applications. This presentation describes the process of modernising the nation's coordinate system, its move to GDA2020 and onto a future time-dependant datum.
