Callpoint Spatial Geocoder - high level overview

Callpoint Spatial Geocoder formula

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.

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.

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 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.

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
