Commencing January 2000, GDA94 was adopted as the national geodetic datum. As a result, locations of mapped features aligned with the geocentric reference used by GPS receivers. Notwithstanding, at the time, GPS was accurate to approximately 10 metres.
Some twenty years later, it is time to update the national geodetic reference system again. GDA2020 reflects the latest changes to the system that underlies Australia’s location information. The GDA2020 datum changes will bring Australia’s national latitude and longitude coordinates into line with global satellite positioning systems. Correspondingly, smartphones and other positioning technologies will be able to accurately locate features marked on our maps.
Industry and government agencies with an investment in spatial data, systems and processes will need to update their data, systems and practices to reflect the new GDA2020 datum. Spatial Vision’s GDA2020 services include assistance, advice and support to ensure your data’s compatibility with GDA2020;
To set your organisation’s investment in spatial data and processes on the right path accordingly, contact Spatial Vision and ask about our GDA2020 services.
