This dataset defines the sedimentary basins and fractured rock provinces which make up the regional hydrogeological divisions of Australia. These hydrogeological provinces have been further classed with regard to either a fractured rock province or a sedimentary basin, distribution of aquifers within the province, and aquifer productivity.

Data quality

Lineage:

Produced from the 1:5 000 000 scale Hydrogeology of Australia map (Jacobsen and Lau, 1987), involving conversion of IGDS files into Arcinfo and creating topology and attributing polygons. Later inclusion of AGSO standard attributes feature and UFI in 1998.

Positional accuracy:

Nominal Scale 1:5,000,000

Highly variable since the original map was derived at 1:5,000,000 scale.

Attribute accuracy:

Accurate for the report the attributes derived from (Jacobsen and Lau, 1987). Further classification of rock provinces was done on the dataset as a whole and into a standard classification so attributes should therefore being reasonably accurate within this basic classification system.

Logical Consistency:

A geoscientist visually inspected the finished dataset to make sure the attributes were accurate and the data were consistent spatially with current scientific information. Tests are also carried out on these data for data completeness, correct spatial representation, attribute accuracy, logical consistency and correctness, and where appropriate for compliance with Geoscience Australia's GIS data dictionary.

Completeness:

The dataset coverage is complete for the whole of continental Australia.
