Callpoint Spatial licenses PSMA CadLite, as well as our value-added editions including Cadlite Extra and Augmented Cadlite.

PSMA CadLite is a comprehensive dataset of cadastral vector data that cover Australia’s land parcels.  It is also known as a Digital Cadastral Database (DCDB).  The dataset consists of two themes:

The primary Cadastre theme: designed for organisations that need a spatial representation of land parcel boundaries.  It includes some 14 million polygons

The Property themes: a companion to the Cadastre themes.  It includes some 11 million polygons

Grey outlines with white shaded regions depict PSMA CadLite Cadastre polygons.

The green and blue shaded regions are sourced from the separate PSMA Transport & Topography Greenspace and Hydrology layers.

Relationships between the Cadastre and Property themes
There are 3 ways in which cadastral and property parcels can inter-relate:

  • Where one cadastral parcel is equivalent to one property
  • Where one property contains many cadastral parcels
  • Where one cadastral parcel contains many properties

These relationships can play an important role in applications such as real estate.

The map below depicts the example where the outer boundary of two adjacent cadastral parcels align with that of one property.

Blue outlines above left: cadastral view (1433//DP754611, 1434//DP754611).

Orange outlines above right: property layer view (property pid NSW1679030)

The map below is an example of the reverse (many property parcels within one cadastre).

Callpoint’s Cadlite Extra and ‘G-NAF Augmented’ Cadlite

In addition to PSMA Cadlite, Callpoint Spatial offers our value-added Cadlite Extra and ‘G-NAF Augmented’ Cadlite editions.

PSMA’s CadLite cadastre polygons with its four attribution columns meets the needs of many applications.  There are some applications though that require a richer set of attribution columns, for instance:

  • The display of the Legal Parcel ID or street numbers within the cadastral parcel
  • 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 additional attribution directly from a given Cadastral polygon.

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 2 enhanced versions: ‘Extra’ and ‘Augmented’


Includes useful columns such as the Parcel ID (which appears in G-NAF).


Provides the full set of columns below, including those derived from the ‘within parcel’ G-NAF analysis.

Data model overview

Please note about Augmented Cadlite:
The processes that perform the augmentation are 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 given cadastre parcel spatially encloses GNAF address points from two differently named streets. This may, but not always, represent a street corner scenario.

In the case of street corners, there are constraints where a G-NAF geocode is present for only one i.e. not both streets.  This means that Augmented Cadlite is not designed for applications where comprehensive tagging of street corner addresses is required.

In the latter case, an alternative approach could start with the use of our street intersections dataset.
