The Atlas of the Officer Basin, South Australia was produce as a co-oprative project between the Australian Geological Survey Organisation and the South Australian Department of Mines, as part of the National Geoscience Mapping Accord.

The Officer Basin is the third largest sedimentary basin in Australia but perhaps the most least understood. This is due largely to its remoteness and inaccessibility.

Hence, there has been little exploration for minerals or hydrocarbons. This Atlas brings together new ideas on the understanding of both the geological structure and occurance of ground water in this basin.

Data quality

Lineage:

The Atlas is a compilation of data both new (seismic 1994) and older (Well logs, previous maps). All interpreted data were compiled using a number of software packages and incorporated in Arc/Info. Final plates (Postscript) were produced using Arc/Info rev 6.1. PDF files were distilled using Adobe Acrobat 3.

Positional accuracy:

The Atlas is a composite product and the positional accuracy depends on the source of the data.

Attribute accuracy:

Positional accuracy for different themes (ATTRIBUTES) are given as 'guestimates'

Base map to 250m

Well locations to 1000m

Geology to 3000m

Isocrons to 6000m

Logical Consistency:

The isocron themes derived from 8100 km of seismic lines, of varying quality; 30 exploritory well deeper than 500m.

Much of the geology is out crop field mapping by the same geologist.
