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.
Note: if you are an NBN reseller and seek a geocoder that also natively references the HFL/ PFL, please refer our AQ Pro
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 updated quarterly by Geoscape Australia.
We have actively used G-NAF and onsold it since 2004, and have proactively enhanced our Geocoder over time.
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.
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
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.
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
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, Indigenous Locations, Regions & Areas, plus 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.
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.
