12 drainage divisions covering Australia, derived from the Australia's River Basins 1997 dataset. This dataset was created by dissolving polygons from the original shapefile based on the DNAME attribute using ArcMap. Primary credit for the source data is given to Geoscience Australia.
Use Cases
- Analyze major hydrological regions based on the 12 drainage divisions.
- Create thematic maps for water resource management based on the derived polygon boundaries.
- Integrate regional drainage data with other environmental datasets for spatial analysis.
Strengths
- Derived from an authoritative source, Geoscience Australia.
- Represents 12 distinct drainage divisions for the entire continent of Australia.
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 source data is from 1997.
Provenance
