Callpoint Spatial Geocoder – high level overview
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 compiled and quarterly updated by PSMA.

We have actively used and licensed G-NAF since 2004, and have proactively enhanced our Geocoder as G-NAF has evolved.

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:

500 HARRIS STREET, ULTIMO NSW 2007

 

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:

SHOP 6T/400 GEORGE STREET, SYDNEY NSW 2000

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:

21 [SUDNEE:SYDNEY],22 [HARIS:HARRIS],31 [ROAD:STREET],41 [SYDNEY:ULTIMO],70,71,82

 

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.

 

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.

Geocode precision

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.

 

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 and 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.

Road category

Are you a researcher and need to know the category of road associated with a given address?

For instance, whether an address represents a local road, national highway or other?

Our Geocoder includes a license option where the Transport Hierarchy Code (THC) from PSMA’s Transport and Topography dataset is returned as a field.

Street Intersections

Do you need to geocode street corners? Our corner capability is built using our quarterly updated Street Intersection dataset.

 

Addresses such as “cnr King & George Sydney” are validated as:

KING STREET CNR GEORGE STREET, SYDNEY NSW 2000

By contrast, “Kong & George Sodnee” is corrected to:

KING STREET CNR GEORGE STREET, SYDNEY NSW 2000

 

In both cases, the coordinates of the street intersection (-33.868736, 151.206953) in this example are returned.

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.
