Surface Hydrology Polygons (National) provides spatial locations and attributes for surface water features across Australia. The dataset includes natural and man-made features such as watercourse areas, swamps, reservoirs, and canals. It is maintained by the Australian Ocean Data Network and was last updated on 2026-04-16.
Use Cases
- Model continental water flow paths based on topological connections between polygon and line features.
- Analyze the distribution of natural water bodies like swamps and watercourse areas.
- Map man-made water infrastructure such as reservoirs and canals.
- Integrate hydrology data with other national-scale environmental datasets.
Strengths
- Dataset covers the entire continental area of Australia.
- Includes both natural and man-made hydrology features.
- Features are designed to topologically connect with hydrology line data.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last update date is 2026-04-16.
