Hydro Point: NSW Inland Water Bodies with Flow Characteristics

New South Wales Hydro Point data represents points for standard inland water bodies where flow is minor. The dataset classifies water bodies as natural or man-made and indicates whether they are perennial, non-perennial, or mainly dry. Spatial Services continuously updates this theme using stakeholder information, aerial imagery, and elevation data.

Use Cases

• Manage state and local government water assets based on water body classification and flow characteristics.
• Support emergency management response and recovery efforts based on the location and type of water bodies.
• Inform climate change and natural resource assessment studies based on the perennial status and type of water points.
• Contribute to the Australian Hydrological Geospatial Fabric based on the standardized NSW hydrography data.

Strengths

• Aligned with the national GDA2020 geodetic standard, improving accuracy and compatibility.
• Continuously updated via stakeholder input, data verification, and aerial imagery cycles.
• Provides the NSW component for the national Australian Water Resources Information System.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial extent are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the NSW government's data collection scope.
