Callpoint - G-NAF Augmented Cadlite®
The PSMA Cadlite® dataset contains a digital representation of some 10.5 million cadastral boundaries around Australia.
The Cadastre theme includes four attribution columns associated with each cadastral polygon. These columns are sufficient for many mapping applications, where the emphasis is display simplicity.
There are other applications that require a richer set of attribution columns, for instance:
- The display of street numbers within the cadastral parcels
- Linkages between Cadlite, G-NAF addresses and other datasets within back-end IT systems
- In-depth spatial analysis
In these cases, it can be very useful to reference an associated street address from a given Cadastral polygon (or vice versa). Inspired by the needs of a fibre optic telecoms carrier, Callpoint developed a set of spatial processes that operate on both Cadlite and G-NAF.
Callpoint Spatial offers two enhanced versions, 'Extra' and 'Augmented'. 'Extra' includes useful columns such as the Parcel ID. 'Augmented' provides the full set of columns, including those derived from the 'within parcel' G-NAF analysis.

Please note:
- The processes that perform the augmentation are very compute intensive. A key benefit of licensing Callpoint Spatial's Augmented Cadlite is that you gain access to these attribution columns 'out of the box'. By contrast, performing these processes 'on the fly' within an application could result in a sluggish user experience, or production delays
- We include two sets of street name/ street number columns to cater for when a corner building includes G-NAF address points from both intersecting streets. Callpoint Spatial has developed fair expertise with street intersections
