Callpoint’s Geocoder

Callpoint Spatial has been geocoding using G-NAF since 2004.  How does this benefit your business?

We have the expertise and capability to help you via our cloud-deployed services:

  • Geocode via web services API (SOAP or REST) to enable your systems to talk directly with ours
  • Batch Geocode a text or Excel file.  When complete, your users receive an email with the download link

Our cloud-deployed Geocoder is located at https://www.callpointspatialgeocoder.com.  We use Australian Data Centres and employ https for end-to-end data encryption.

Callpoint Spatial Geocoder – high level overview

Key Features

Built using G-NAF
Callpoint'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.
Callpoint has actively used and licensed G-NAF since 2004. We have proactively enhanced our Geocoder as G-NAF has evolved.
Extensive address parsing
Addresses can include extraneous text, especially so in legacy databases. Callpoint's Geocoder includes extensive address parsing and resolution capabilities. For example:
s6 near rear lane entrance 400 ggeorge st sydney
Callpoint's 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'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, we return the Collector District.
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?

Callpoint's 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? Callpoint's Geocoder 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.
Batch or API
Do you want the flexibility to geocode either a text/ Excel file or via API (REST/ SOAP)? Callpoint's Geocoder provides both options.
G-NAF Live
PSMA G-NAF is updated quarterly. In some cases, what's needed is access to more recently released addresses. Callpoint's Geocoder includes, as a licensed option, integrated access to G-NAF Live
