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, and has seen it considerably evolve.
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 business processes.
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.
Street Intersections
Callpoint has been generating its Street Intersection dataset each quarter since 2009, based on PSMA Transport & Topography data.
Addresses such as "cnr King & George Sydney" are validated as:
KING STREET CNR GEORGE STREET, SYDNEY NSW 2000

By contrast, "Kong & George Sodnee" are corrected to:
KING STREET CNR GEORGE STREET, SYDNEY NSW 2000

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