Data quality

Lineage:

The data is derived from the World Earthquake Database, extracted directly and converted into a spatial Arcinfo coverage. Items feature and UFI are added to complete the quality assurance.

Positional accuracy:

Nominal Scale 1:100,000

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 the quality-controlled database it was derived from. 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 Australian Jurisdictional Area.
