Aggregated Way: NSW Road Segments Grouped by Common Attributes

Aggregated Way is a line feature class representing sets of New South Wales road segments grouped by shared function or characteristics. The dataset uses the GDA2020 geodetic datum, aligning with the national standard for improved accuracy and compatibility. It is provided by Spatial Services, a business unit of the Department of Customer Service NSW.

Use Cases

• Analyze road network functional groupings based on WayType and WayNumber attributes.
• Map road corridors sharing common names based on aggregated RoadNameBase, RoadNameType, and RoadnameSuffix values.
• Support foundational spatial data frameworks for transportation planning and analysis.

Strengths

• Uses the GDA2020 datum, improving positional accuracy and national consistency.
• Positional accuracy is defined per map scale, ranging from 0.25 meters at 1:500 scale to 50 meters at 1:100,000 scale for 90% of well-defined points.
• An ongoing program aims to upgrade spatial location and accuracy.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• Aggregated Ways do not have an implied topology and are not guaranteed to form a complete, connected network.
• The description metadata is limited; actual data quality requires manual inspection after download.
