Theme Working Group or Committees
Positioning is Australia's authoritative, reliable, high accuracy spatial referencing system. The positioning service defined under this theme includes the coordinates and their uncertainty of all location-based data promulgated from, or related to, the Australian Fiducial Network (AFN) and the defining Australian Height Datum tide gauge stations. The positioning service is underpinned by physical geodetic infrastructure, such as the survey marks and Global Navigation Satellite System (GNSS) networks, geodetic modelling (e.g. the coordinate transformations), and definitions of the geoid and bathymetric reference surfaces.
