Geocode

A point feature for an address spatially defined by a coordinate. In G‑NAF an address may have multiple geocodes representing various real world features (e.g. parcel, property, building centroid, street centroid, locality centroid etc.) associated with a physical address. The geographic coordinates are expressed as latitude/longitude in decimal degrees.

Geocode Level Type

The geocode level type indicates which geocodes have been assigned to an address. Every address within G‑NAF must have a locality level geocode. Addresses may also have a street level geocode and a parcel level geocode. 

Geocode Priority

G‑NAF is able to assign multiple geocodes to an address. The geocode priority is a priority order established by PSMA to enable a default geocode to be assigned to each address which represents the geocode of the highest precision currently assigned to an address.

Where flat number information exists for an address then this forms part of a Secondary Address and a linkage made to the Primary Address. Alternatively a Primary Address can be linked to one or more Secondary Addresses by PSMA where identified by an address contributor (e.g. involves private road in complex development, public housing estates etc.)

Raster Data

The raster data model uses a grid to cover the space and the value of each cell (pixel) in the grid to correspond to the characteristic of the geographic feature at the cell location. The cell is the smallest unit in the grid. A grid is a matrix of cells. Raster data could come from many sources such as aerial photographs, satellite imagery, digital pictures or scanned maps.

Raster Resolution

This is a measure of an image's pixel/cell dimensions, providing information on the level of detail of features it represents. The smaller the value the higher level of detail represented.

Reference Data

Each address entering G‑NAF is tested to ensure it can be matched against the geospatial region to which it relates: state, locality and street. The datasets used for this geospatial verification are:

National Road Centreline Dataset (PSMA Transport & Topography)

Gazetted Locality Boundaries for Australia (PSMA Administrative Boundaries).

These two datasets are commonly referred to as the Reference Data.

Release Report

This is the report provided with each release of a product and will outline key issues and production changes applied during the assembly. Included will be statistics and change volumes.

Resolution

Rules

Rules are at times applied to contributor addresses as part of the G‑NAF processing where errors are identified in the addresses such as the incorrect spelling of street names, incorrect street types or incorrect localities. The application of these rules generates alias street localities or localities depending on the rule applied.
