Utility Water Supply Canals in New South Wales, Australia

A line feature dataset of artificial watercourses for conveying water in New South Wales, Australia. The dataset is part of Spatial Services Defined Administrative Data Sets and was initially published on 06/02/2020. It is provided by Spatial Services, a business unit of the Department of Customer Service NSW.

Use Cases

• Map water supply infrastructure networks based on line geometries.
• Analyze spatial relationships between canals and other land cover or transport themes.
• Support hydrological modeling and water resource management planning.
• Update maps and applications transitioning from the GDA94 to GDA2020 coordinate reference system.

Strengths

• Geometries align with other authoritative Spatial Services Defined Administrative Data Sets.
• Positional accuracy is maintained relative to themes like transport, imagery, and land cover.
• Data was captured using sources at scales ranging from 1:500 to 1:250,000.

Limitations

• The service is scheduled for retirement, requiring users to transition to a new GDA2020 service.
• Column-level documentation is absent; field semantics must be inferred after download.
• The spatial reference is GDA94, which cannot be easily consumed into GDA2020 environments.
