Ord Basin Hydrogeological Inventory

Geoscience Australia's Ord Basin dataset provides descriptive attribute information for spatial groundwater features. It covers approximately 8000 square kilometres on the Western Australia-Northern Territory border, detailing the basin's geology, hydrogeology, and land use. The data supports analysis of an intracratonic sedimentary basin with up to 2500 metres of Cambrian and Devonian rocks.

Use Cases

• Groundwater resource assessment based on hydrogeological attribute data.
• Basin analysis and geological mapping using stratigraphic and structural descriptions.
• Environmental impact studies referencing land use and industry type themes.
• Regional water management planning supported by surface water and groundwater data.

Strengths

• Covers a specific, defined geological area of about 8000 square kilometres.
• Structured around detailed thematic groups including Geology, Hydrogeology, and Groundwater Management.
• Part of a national inventory (National Hydrogeological Inventory), suggesting a standardized framework.

Limitations

• Key metadata such as row count, specific column names, file size, and license are not provided.
• The dataset's freshness is unclear as the last update date is in the future (2026-05-14), indicating a potential metadata error.
• Descriptions are repeated verbatim across multiple platform entries, offering no additional detail.
