Different users have different requirements of the data contained in the G-NAF(Geographic National Address File). NAVIGATE has engineered the G-NAF data sets and restructured the data for friendly and easy integration with clients GIS and Information Systems.

NAVIGATE uses the G-NAF (Geographic National Address File) product from PSMA Australia as the source for reference databases. The G-NAF is delivered to NAVIGATE as a highly normalised data model that includes a number of data tables and a series of associated look-up tables containing approximately 13 million addresses and geocodes. The structure used by PSMA is well suited to compiling and checking the G-NAF, but most GIS users require a simpler “flattened” structure that facilitates easy and simultaneous access to all relevant parts of an address record without writing multi-table queries.  NAVIGATE has taken the 30 plus tables that ship with G-NAF and combined them into a single table GNAF_FLAT, that forms core of our G-NAF product suite.

NAVIGATE remarkets Australia Post Postcodes boundaries that have been released by PSMA Australia in the 2007 release. Both postcode boundaries and postcode centroids are available.

Postcodes are Administrative Areas developed by Australia Post to facilitate the efficient delivery of mail. A postcode may be classed either as an area or a point-type postcode (eg. Post office box).  A postcode may have many polygons defining its boundary. The original polygon data supplied by PSMA has been clipped and infilled by NAVIGATE to coincide with ASGS state polygons. PSMA boundaries within each state have been honoured except where adjustments have been made to remove voids and overlaps.

The National Cadastre data set is a seamless national cadastral database of Australia's 11 million parcels. The digital cadastral boundaries and their legal identifiers have been derived from the relevant bodies from each Australian State and Territory jurisdiction.

The Administrative Boundaries dataset is a collection of polygon layers applicable to a wide variety of uses. PSMA Australia receives and collates data from its primary contributors and populates a standardised and normalised Integrated Data Model (IDM). The data is managed in state based schemas that separately store the primary attributes data, individual geometry and meaningful explanatory look-ups. There are differences in content and boundary definitions between jurisdictions. for example some will incorporate a detailed version of the coastline, others may omit significant bays and estuaries while others have polygons stretching far out to sea to cover islands yet may not have a cartographic coastline at all.

The Points of Interest dataset contains in excess of 130,000 points of interest with feature code and name attribution.

Some of the feature categories include:
