PSMA G-NAF®

This map represents a G-NAF overlay on a satellite image of Australia.  Each orange pixel represents one G-NAF address.

PSMA G-NAF (Geocoded National Address File) is Australia’s authoritative geocoded address dataset.

Callpoint Spatial package G-NAF in various forms and can also include attribution from PSMA and other datasets to meet your overall needs.

Features

Core G-NAF features include:

  • A national geocoded address dataset
  • Uniform data structure across all States and Territories
  • Breadth of interlinked tables to help support a range of applications
  • Links to PSMA’s other datasets such as Cadlite, Transport & Topography, Geoscape and Administrative Boundaries
  • PSMA’s commitment to ongoing data improvements
  • Updated on a consistent, quarterly schedule in late February, May, August and November

 

Why Callpoint Spatial

Reasons include:

  • Our lengthy and in-depth G-NAF experience, for instance
    • We engaged with PSMA Australia during the first IPND address accuracy audit that we conducted for ACMA in 2003. We recommended that G-NAF be used as the address reference dictionary for future audits; this recommendation was adopted
    • We pioneered the use of G-NAF in our Local Government Area (LGA) Broadband Analysis reports that started in 2004
    • We won the Metropolitan Broadband Blackspot Program (MBBP 2005) geospatial consultancy tender and extensively used G-NAF for that project
    • We transitioned our address validation/ geocoding engine to G-NAF during 2004, and this has since been extensively refined. The engine is embedded within Callpoint Spatial’s Geocoder and Callpoint AQ Pro®
    • Through G-NAF, we have helped 40 Australian telcos with their spatial needs
  • Our advisory capacity
  • One stop – we license all seven other PSMA datasets
  • Ability to license either for your internal business use (EULA) or as part of a solution you are offering to your customers (Secondary Resellers)
  • Inclusion of PSMA delivered technical support and warranties
  • The wide range of standard formats and customisation options that we provide

Callpoint Spatial value-added G-NAF examples

As shipped by PSMA, the main Address Detail table includes 35 columns.  Many customers however seek G-NAF that has been pre-processed and enriched so that it can be quickly put to productive use.

Callpoint Spatial specialises in cross-linking between PSMA datasets.  We can also augment with third party data such as from ABS and Australia Post.

All our value-added datasets have three digit product codes.  Example below.

Our GIS versions can be readily opened within popular mapping applications.
