Description
A line feature class representing road sections with common attributes, terminating at physical ends or same-grade intersections. The dataset includes features such as Vehicular Track, Pathway, Continuity Line, Standard Road, On-off Ramp, and Dual Carriageway, captured using methods like GPS, cadastre tracing, or orthorectified imagery. It is published and maintained by Spatial Services, a business unit of the Department of Customer Service NSW, with daily updates and an initial publication date of February 6, 2020.
Use Cases
Analyze road network connectivity and topology using the line feature class and intersection termination attributes.
Classify and map different road types like Standard Road, Dual Carriageway, and On-off Ramp for infrastructure inventory.
Assess positional accuracy of road segments by referencing the documented capture scales ranging from 1:500 to 1:250,000.
Model traffic flow or plan routing by utilizing the segmented road geometry and feature continuity lines.
Strengths
Daily update frequency ensures current road network information.
Positional accuracy adheres to National Mapping Council standards, with tolerance defined per map scale (e.g., 0.25m at 1:500 scale).
Comprehensive feature classification includes six distinct road segment types.
Limitations
The spatial reference is GDA94, which is scheduled for retirement and cannot be easily consumed in GDA2020 coordinate systems.
Specific row count and total geographic extent are not provided in the available metadata.
Accuracy varies based on source scale, from 1:500 to 1:250,000, introducing inconsistency in feature precision.
