Callpoint Spatial offers two specialised datasets that meet specific needs in the logistics and infrastructure sectors. These datasets are generated by Callpoint Spatial developed processes that use PSMA datasets as input sources.
National Street Intersection Dataset
This dataset (also known as the Street Junction data, Cross-Street dataset, Intersecting Street or Street Corner dataset) is a comprehensive dataset of street intersections for each State across Australia. Callpoint Spatial has been generating this dataset quarterly since 2009.
The dataset enables can be queried to find all the intersections of a particular street in a given locality.

Cross-Street Distances Dataset
Callpoint Spatial’s Cross Street Distances dataset provides details of the nearest cross-streets for each geocoded G-NAF address record.
Table columns include the names of the nearest cross-streets and “along street centreline” distance to the nearest cross-streets.
The dataset is generated using Callpoint Spatial proprietary geospatial software processes that operate on PSMA G-NAF and Transport & Topography®.
The Cross-Street Distances dataset finds application in the infrastructure rollout and logistics sectors.
|G-NAF Address||Nearest Cross Street||Distance|
|46 ARTHUR CIRCLE||TASMANIA CIRCLE||36|
|44 ARTHUR CIRCLE||TASMANIA CIRCLE||64|
|42 ARTHUR CIRCLE||TASMANIA CIRCLE||91|
|40 ARTHUR CIRCLE||FURNEAUX STREET||117|
|38 ARTHUR CIRCLE||FURNEAUX STREET||90|
|36 ARTHUR CIRCLE||FURNEAUX STREET||64|
|34 ARTHUR CIRCLE||FURNEAUX STREET||37|
|32 ARTHUR CIRCLE||FURNEAUX STREET||10|
Above: results table for a section of Arthur Street, Forrest ACT. For each G-NAF address, the ‘Nearest Cross Street’ column indicates the name of the nearest street intersection, and the Distance column indicates the ‘along street centreline’ distance (in metres) to that cross street.
