Geological lines (contacts, faults, linears), geological rock units, and structure data derived from 1:50,000 and 1:63,360 Digital Geological Atlas printed map series and 1:25,000 digital geology data where available. Geological units and boundaries have been generalised and compiled for 1:250,000 scale. The digital data is available as a seamless state wide coverage and is used to produce the Digital Geological Atlas 1:250,000 Scale map series.

Data is derived from 1:50,000 and 1:63,360 Digital Geological Atlas printed map series and 1:25,000 digital geology data where available. The data has been generalised and compiled to fit the 1:250,000 scale digital topographic base.

Position Accuracy: Generalisation of rock units to 1:250,000 scale gives a final accuracy of up to +-250m. Attribute Accuracy: Database has not been verified, but database contains an attribute describing reliability. Logical Consistency: All polygons, lines and point data labelled. All vertices are snapped and all polygons close. All data is topologically related. There are no duplicates Completeness: Statewide coverage, including King and Flinders Islands. Many attribute fields are unfilled.
