Wiso Basin Hydrogeological Inventory for Central Northern Territory

A 140,000 square kilometre intra-cratonic basin in the central Northern Territory, part of the Centralian Superbasin. This dataset contains descriptive attribute information grouped into themes including location, demographics, geology, hydrogeology, and land use, published by the Australian Ocean Data Network. The data was last updated on 2026-06-23.

Use Cases

• Map groundwater management zones based on administrative boundaries and hydrogeological features.
• Analyze the relationship between surface water features and groundwater systems described in the dataset.
• Study basin stratigraphy and depositional history using the described Cambrian, Ordovician, and Devonian units.
• Model groundwater potential in the Lander Trough based on its varied stratigraphic sequence.

Strengths

• Covers a large, defined area of approximately 140,000 square kilometres.
• Descriptive information is organized into 11 specific thematic groups, including hydrogeology and groundwater management.
• Includes detailed geological context, such as the composition of middle Cambrian strata making up about 80% of the basin.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au.
