The PSMA Transport & Topography (T&T) dataset includes vector data for:

Street centrelines

Airports & airport runways

Railway lines and stations

Hydrology and minor water boundaries

National Parks, Urban Parks and reserves

The topologically connected street vector data fills particular needs within navigation and routing.

The complete set of T&T layers meets a range of demographic, spatial analysis and cartographic applications.

The street centreline layer includes a range of attribution columns. For example:

The THC contains a three-digit code that specifies whether the street is a local road, national highway etc.

For examples, please refer the different coloured road layers in the map below.


This links to the same column within PSMA G-NAF.


The GRC identifies whether a given road segment is at ground level, above ground (e.g. an overpass) or below ground (e.g. a tunnel).

The GRC finds use within routing and navigation applications.
