The 1:500 000 State interpreted bedrock geology (DMIRS-016) is one of three digital data layers that make up the 1:500 000 geological map of Western Australia. The other two are the 1:500 000 State Cenozoic geology and the 1:500 000 State linear structures layer (DMIRS-015). Compilation is based on published 1:100 000 and 1:250 000 Geological Series maps of Western Australia, together with GSWA and GA (AGSO, BMR) regional geological maps at scales from 1:250 000 to 1:1 000 000. Information from these maps has been modified locally using geophysical datasets (magnetics, radiometrics and gravity), remote sensing imagery (ASTER and LANDSAT), seismic and magnetotelluric profiles, drilling, and unpublished geological mapping. The nomenclature and hierarchy for the lithostratigraphic units are based on the GSWA Explanatory Notes System (extracted April 2016). Data are held in GDA94 decimal degrees. This dataset was formally known as 1:500 000 State interpreted bedrock geology (DMP-013)
