Fuzzy Extent Water Line Features for New South Wales

New South Wales water data includes the Fuzzy Extent Water Line feature class, representing approximate centerlines of formally named water features with indistinct extents. Spatial Services (DCS) provides this hosted feature layer, initially published in February 2020. It forms the NSW component of the Australian Hydrological Geospatial Fabric.

Use Cases

• Mapping approximate centerlines of river-like features such as Anabranches, Arms, and Channels for hydrological modeling.
• Integrating the 'Fuzzy Extent Water Line' feature class into the Australian Water Resources Information System (AWRIS).
• Supporting emergency management and disaster risk reduction by providing base hydrology data for flood planning.
• Environmental monitoring and planning using the geospatial representation of indefinite water feature extents.

Strengths

• Data is part of the nationally critical Australian Hydrological Geospatial Fabric.
• Feature class includes specific designations like Anabranch, Arm, Canal, and Channel.

Limitations

• Spatial reference is WGS 84 aligned to GDA94, which may cause misalignment in GDA2020 environments.
• The service is scheduled for retirement, indicating potential future access issues.
