Interpolated surface representing the spatial distribution of permeability within the following formations in the Great Artesian Basin: 1. Birkhead Formation 2. Cadna-owie and Bungil formations 3. Evergreen Formation 4. Hooray Sandstone and equivalents 5. Hutton Sandstone 6. Precipice Sandstone Data is available as a raster in ESRI Grid and ESRI ASCII grid formats. This GIS data set was produced for the Great Artesian Basin Water Resource Assessment. Rasters were used in: Figure 5.26 of Ransley TR and Smerdon BD (eds) (2012) Hydrostratigraphy, hydrogeology and system conceptualisation of the Great Artesian Basin. A technical report to the Australian Government from the CSIRO Great Artesian Basin Water Resource Assessment. CSIRO Water for a Healthy Country Flagship, Australia.
