New South Wales Aggregated Road Network Features

Aggregated Way is a line feature class representing sets of road segments grouped by common attributes like WayType and RoadNameBase. The dataset is part of the NSW Transport Theme within the Foundation Spatial Data Framework, published by Spatial Services, a business unit of the Department of Customer Service NSW. Initial publication was on 12/02/2020, with a stated data currency date of 01/01/3000 indicating its intended long-term reference role.

Use Cases

• Analyze road network composition by aggregating segments based on shared WayType and RoadNameBase attributes.
• Map and visualize functional road corridors for planning using the line feature geometry and WayNumber classification.
• Support transportation studies by identifying road segments that belong to multiple Aggregated Way groups, indicating shared characteristics.

Strengths

• Dataset is part of the authoritative Foundation Spatial Data Framework for New South Wales.
• Source data accuracy ranges from 1:500 to 1:250,000 scale according to cited mapping standards.
• Features are derived from aggregation of underlying segment data with consistent attribute values.

Limitations

• The service is scheduled for retirement, indicating it is being replaced by a GDA2020-aligned version.
• Spatial reference is WGS 84 aligned to GDA94, which may cause misalignment in modern GDA2020 coordinate systems.
• Aggregated Ways do not have implied topology and are not guaranteed to form a connected network.
