Geocentric Datum of Australia

The Geocentric Datum of Australia (GDA) is a coordinate reference system that provides precise geographic positions across Australia. It serves as a standardized framework for mapping, surveying, and navigation, aligning location data to a common Earth-centered coordinate system. GDA ensures consistent and accurate positioning by referencing the Earth's center of mass, improving the reliability of spatial information for applications like construction, mapping, and environmental management. Essentially, it acts as Australia's definitive ‘personal GPS’ coordinate system, enabling professionals to connect and compare geographic data seamlessly.
