GA Bedrock and Surficial Geology

This OneGeology WMS service comprises a 1:2,500,000 scale digital geological map of Australia (2000) and 1:1,000,000 scale digital geological maps of Eastern Australia, Northern Territory, South Australia and Western Australia (2008). A scale limiter is placed upon the 1:1,000,000 scale data so that this detailed data can only be viewed when zoomed in to an appropriate viewing scale. The data represents the surface geology, including surficial unconsolidated deposits and outcropping (or near-outcropping) bedrock, geological unit contacts, faults and shear zones. The geological unit datasets are each represented by two layers - one classified according to the AGE of unit, and another classified according to LITHOSTRATIGRAPHY. Lithostratigraphic classification and description of the 1:1,000,000 scale data is according to the Australian Stratigraphic Units Database (https://www.ga.gov.au/oracle/stratnames/index.jsp). The 1:2,500,000 scale data employs a broader and more simplified classification of Australian geological units. This data and other digital geological datasets of Australia are available free from the Geoscience Australia website at https://www.ga.gov.au/products/servlet/controller?event=DEFINE_PRODUCTS.
