Callpoint Spatial has been generating the National Street Intersection dataset quarterly since 2009. We use the PSMA Transport & Topography dataset as our source data.
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.
The dataset can be used for instance to find all the intersections of a particular street in a given locality.
This has application in traffic management and logistics.
