Road Name Extent for New South Wales Transport Network

Road Name Extent is a line feature class representing aggregated road segments that share the same local road name and are relatively contiguous. It is part of the NSW Transport Theme within the Foundational Spatial Data Framework (FSDF) and has been updated to the GDA2020 spatial reference system. The dataset is provided by Spatial Services, a business unit of the Department of Customer Service NSW.

Use Cases

• Map road name continuity for navigation systems based on aggregated line segments.
• Perform spatial analysis on transport networks based on the line feature class.
• Integrate road data with other foundational spatial datasets based on the FSDF framework.
• Update legacy GIS systems to the GDA2020 standard based on the new service version.

Strengths

• Data is aligned with the national GDA2020 standard, improving accuracy and compatibility.
• Spatial accuracy is defined, ranging from 0.25m to 50m depending on the source map scale.
• Dataset covers the full state of New South Wales.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data currency date is listed as 01/01/3000, which is likely a placeholder and obscures actual freshness.
