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.

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

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

 

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.
