Abstract
The Surface Geology of Australia (2010 edition) is a seamless national coverage of outcrop and surficial geology, compiled for use at or around 1:1 million scale. The data maps outcropping bedrock geology and unconsolidated or poorly consolidated regolith material covering bedrock. Geological units are represented as polygon and line geometries, and are attributed with information regarding stratigraphic nomenclature and parentage, age, lithology, and primary data source. The dataset also contains geological contacts, structural features such as faults and shears, and miscellaneous supporting lines like the boundaries of water and ice bodies. The dataset has been compiled from merging the seven State and Territory 1:1 million scale surface geology datasets released by Geoscience Australia between 2006 and 2008, correcting errors and omissions identified in those datasets, addition of some offshore island territories, and updating stratigraphic attribute information to the best available in 2010 from the <A href="http://www.ga.gov.au/products-services/data-applications/reference-databases/stratigraphic-units.html">Australian Stratigraphic Units Database</A>. The map data were compiled largely from simplifying and edgematching existing 1:250 000 scale geological maps. Where these maps were not current, more recent source maps, ranging in scale from 1:50 000 to 1:1 million were used. In some areas where the only available geological maps were quite old and poorly located, some repositioning of mapping using recent satellite imagery or geophysics was employed.

The dataset has been compiled from merging the seven State and Territory 1:1 000 000 scale surface geology datasets released by Geoscience Australia between 2006 and 2008, correcting errors and omissions identified in those datasets, addition of some offshore island territories, and updating stratigraphic attribute information to the best available in 2010 from the Australian Stratigraphic Units Database (http://www.ga.gov.au/oracle/stratnames/index.jsp). The map data were compiled largely from simplifying and edgematching existing 1:250 000 scale geological maps. Where these maps were not current, more recent source maps, ranging in scale from 1:50 000 to 1:1 000 000 were used. In some areas where the only available geological maps were quite old and poorly located, some repositioning of mapping using recent satellite imagery or geophysics was employed.
