A Local-State Government Spatial Data Sharing Partnership

A Local-State Spatial Data Sharing Partnership Model to Facilitate SDI Development
nine state and federal mapping agencies. In 2001, after consideration of the growth and
operation of the PSMA consortium, the public company PSMA Australia Limited was
established.

The achievements of the PSMA, initially through ANZLIC, and now in its own right have
been significant and include the compilation of national data sets including topographic
mapping, cadastral land parcels (CADLite), transportation, administrative boundaries and
the Geocoded National Address File (G-NAF). Two of these national data sets are of
particular interest to this research, namely the cadastral land parcels data set, but especially
the geocoded national address file which relies heavily on the capture and exchange of
information between local and state governments.
The planning for a national geocoded address file began in 1995. After a pilot study in
1996, cost estimates were compiled to extend the work to a national level. Further
feasibility studies and testing identified the need for a national address file and a national
standard for street addressing (Paull 2003). The national street address standards were
completed in 2003, PSMA put the G-NAF project to tender in mid 2003, and the first
version of G-NAF was completed in 2004. G-NAF is Australia’s first authoritative
geocoded address index for the whole country, listing all valid physical addresses in
Australia (PSMA 2005). It contains approximately 12.6 million physical addresses, each
linked to an unique geocoded address.
