Road Name Extents for New South Wales Transport Network

New South Wales road name extents are represented as a line feature class aggregating contiguous road segments sharing the same local name. The dataset is part of the state's Foundation Spatial Data Framework, managed by Spatial Services, a business unit of the Department of Customer Service NSW. It was initially published in February 2020.

Use Cases

• Map road network connectivity by analyzing the line geometry and road name attributes.
• Perform spatial joins with other transport datasets using the geographic extents of named roads.
• Update legacy mapping applications by transitioning from the GDA94 to the GDA2020 spatial reference service.
• Assess positional accuracy for planning applications using the documented scale-dependent accuracy standards (e.g., 0.25m at 1:500 scale).

Strengths

• State-wide spatial coverage of New South Wales.
• Documented positional accuracy standards ranging from 0.25m to 50m depending on source map scale.
• Part of the authoritative NSW Foundation Spatial Data Framework.

Limitations

• Spatial reference is GDA94, which may cause misalignment in GDA2020 environments.
• Data currency date is listed as 01/01/3000, indicating potential staleness for current analysis.
• Specific row counts and update frequency are not provided.
