Key features

Built using G-NAF

Callpoint Spatial’s Geocoder operates solely on Australian addresses.

It is based on and highly optimised for G-NAF, being the authoritative Australian geocoded address dataset updated quarterly by Geoscape Australia.

We have actively used G-NAF and onsold it since 2004, and have proactively enhanced our Geocoder over time.

High yield

At times there are multiple errors within an address.

For example:

500 haris rd sudnee

Callpoint’s Geocoder dives deep to extract the relevant address within G-NAF being:


Comprehensive result codes

Callpoint Spatial’s Geocoder delivers a comprehensive, informative set of structured result codes. This differs to the single digit only approach offered by some alternatives.


In the above example, the result code includes:



Where the following codes are defined as:

21: LocalitySoundex; 22: StreetCloseWord

31: StreetTypeDifferent; 41: LocalityNeighbour


In other words, our Geocoder returns for each address, the specific transformations that it performed. This can be useful for your audit and analysis processes.

Extensive address parsing

Addresses can include extraneous text, especially so in legacy databases.

Callpoint Spatial’s Geocoder includes extensive address parsing and resolution capabilities.

For example:

s6 near rear lane entrance 400 ggeorge st sydney

Our Geocoder extracts the relevant address within G-NAF:


API or Batch

Do you want the flexibility to geocode either a text/Excel file or via API (REST/SOAP)?

Our Geocoder provides both options.

Geocode precision code

Fallback options beg the question: to what level of precision do the latitude longitude coordinates refer?

The Geocode Precision field returns a single value that indicates whether the returned coordinates are at the address, unique road feature or unique locality feature level. For instance, the above example returns '2', which means:

Within Address Site Boundary

Rich ABS attribution

To help with geo-demographic analysis, we return ABS data including the associated Mesh Block, Mesh Block Category, SA1, SA2, SA3, SA4, Indigenous Locations, Regions & Areas, plus Remoteness Index Name and Code.

To help with historical cross-referencing, the Collector District is also returned.

Our Geocoder also returns the 28 SEIFA columns across the four groups being IRSAD, IRSD, IER and IEO.

Fallback options

A number of user settable options are provided to cater for a variety of use cases.

These include range tolerance, street locality and locality level.
