Data quality

Lineage:

Onshore refraction shot point coordinates, all surveyed points, to 3rd order surveying standard, are extracted from a PETROSYS database. The extracted ASCII file data is used to create a point coverage in Arcinfo, adding the identifying information, as well as feature and ufi (necessary QA/QC items).

Positional accuracy:

Nominal Scale 1:10,000

Seismic station coordinates are all surveyed points, to 3rd order surveying standard and are extracted from a database so positional accuracy is high.

Attribute accuracy:

High, only one attribute is extracted directly from a database.

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 available at http://www.ga.gov.au/standards/datadict.html.

Completeness:

The dataset coverage is complete for continental Australia.
