Hydro Area: NSW Water Bodies and Watercourses, GDA2020 Geodatabase

A polygon feature class defining hydrographic feature types for New South Wales, Australia. The data includes waterbody areas and watercourses, classified as perennial, non-perennial, or mainly dry, and is continuously updated by Spatial Services. It provides the NSW component for the Australian Hydrological Geospatial Fabric and Australian Water Resources Information System.

Use Cases

• Model water resource availability based on waterbody and watercourse classifications.
• Plan for climate change impacts using data on perennial and non-perennial water features.
• Support emergency management and hazard mitigation with detailed hydrographic mapping.
• Inform natural resource assessment and environmental monitoring for agriculture and mining.

Strengths

• Data is aligned with the national GDA2020 standard, improving accuracy and compatibility.
• Continuously updated from aerial imagery, elevation data, and stakeholder sources.
• Serves as a critical input to national water resource information systems.

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 requires verification.
