This includes well known aquifers, including Great Artesian Basin, Murray Basin, Daly Basin and Perth Basin. Where possible they are attributed with their local name to allow users to identify known aquifers in an area of interest.Aquifers are categorised as belonging to upper, middle or lower groups. This is based on the National Aquifer Framework, which groups aquifers by geological strata and age. The classification is indicative and designed to give only an indication of where complex layered aquifers occur.The aquifer boundaries dataset is sourced from the National Groundwater Information System (NGIS). Input datasets are listed on the NGIS Copyright webpage. Detailed discussion of the methodology used is found in the Bureau's aquifer boundaries paper.Information about aquifer boundaries fields:LocalHGUName—Jurisdictional name of Hydro Geological Unit (HGU)NafHGCName—National Aquifer Framework (NAF) name of Hydro Geologic Complex (HGC)ProvinceName—Name of groundwater province or basinSource—Jurisdictional data provider</DIV></DIV></DIV> We request attribution as © Commonwealth of Australia (Bureau of Meteorology) 2020 NGIS National Groundwater Information System Australian Groundwater Explorer Australian Groundwater Insight aquifer groundwater hydrogeology Australia Bureau of Meteorology <DIV STYLE="text-align:Left;"><DIV><DIV>Creative Commons Attribution V4.0 (CC BY 4.0)</DIV></DIV></DIV> 1 112.921484 159.130997 -9.219940 -43.643052 Enterprise Geodatabase Feature Class dataset EPSG 9.8(3.0.1) 293 Simple FALSE 293 TRUE FALSE aquifer_boundaries Feature Class 293 objectid objectid OID 4 10 0 Internal feature number.
