Utility Water Supply Canals in New South Wales, Australia

A line feature dataset of artificial watercourses used to convey water across New South Wales, Australia. The data is part of the Spatial Services Defined Administrative Data Sets and aligns with other administrative themes. It is provided by Spatial Services, a business unit of the Department of Customer Service NSW, and has been updated to the GDA2020 geodetic standard.

Use Cases

• Map water distribution networks based on the line feature geometry.
• Analyze the spatial relationship of canals to other land features based on alignment with other administrative datasets.
• Support infrastructure planning and maintenance using the defined positional accuracy standards.
• Integrate with modern positioning technologies using the updated GDA2020 coordinate reference system.

Strengths

• Updated to the GDA2020 national geodetic standard, improving accuracy and compatibility.
• Positional accuracy is defined per map scale, ranging from 0.25m at 1:500 to 50m at 1:100,000.
• Aligns with and maintains positional relationships to multiple themes from the NSW Foundation Spatial Data Framework.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on New South Wales.
