Callpoint Spatial Geocoder - high level overview
Our cloud-deployed Geocoder is located at https://www.callpointspatialgeocoder.com
We use Australian Data Centres that are certified to ISO27001 and employ https for end-to-end data encryption.
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.
At times there are multiple errors within an address.

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.
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 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
Extensive address parsing
Addresses can include extraneous text, especially so in legacy databases.
Callpoint Spatial’s Geocoder includes extensive address parsing and resolution capabilities.
