Data quality

Lineage:
Basin outlines were digitised in Arcinfo from the 1:2 500 000 Geological Map of Australia in 1992. Their boundaries were updated in Petroseis in 1994 by adding some offshore basins and sub-basins from the unpublished Tectonic Elements of Australia map. The 1996 update of the sedimentary basins data set included: bringing changes made to the offshore basins in 1994 into the Arcinfo coverage, further editing the offshore basin boundaries, adding volcanic provinces of the continental margin and classifying basin boundaries into basins, sub-basins and coastline.

Positional accuracy:
Nominal Scale 1:5,000,000

Attribute accuracy:
High

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:
Complete for Continental Australia and some offshore areas.
