Surface Hydrology Polygons for Australia, Aggregated from Jurisdictional Data

Geoscience Australia aggregates the best available jurisdictional data to provide a geometric representation of major hydrographic polygon elements. This dataset includes both natural and artificial features and is intended as a basis for producing consistent hydrological information. The data was last updated on 2026-04-30.

Use Cases

• Map water bodies and drainage basins based on the geometric representation of hydrographic polygons.
• Model surface water flow and connectivity using the dataset's representation of natural and artificial features.
• Define hydrological features for environmental impact assessments based on the aggregated jurisdictional data.
• Create consistent cartographic products for hydrological information as described in the dataset's purpose.

Strengths

• Data is described as the 'best available' supplied by Australian jurisdictions.
• Dataset provides a geometric representation of both natural and artificial hydrographic elements.
• Intended for defining hydrological features with attributes, suggesting a structured schema.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Freshness should be verified despite the 2026-04-30 update date, as the description does not specify a collection period.
