Dataset History
The polygon shapefile within this dataset was created by erasing the Cadna Owie - Hooray aquifer extent shapefile: CadnaOwie_Hooray_Aquifer_Extent.shp (GABATLAS - Cadna-owie-Hooray Aquifer and Equivalents - Thickness and Extent, GUID: bc55589c-1c6f-47ba-a1ac-f81b0151c630) from the Great Artesian Basin extent shapefile: GAB_Hydrological_Boundary.shp (Great Artesian Basin - Hydrogeology and Extent Boundary, GUID: 020957ea-4877-4009-872c-3cacfb6f8ded).
Using the Erase tool in ArcGIS (Analysis Tools > Overlay > Erase) with the following input parameters:
in_features: GAB_Hydrological_Boundary.shp
erase_features: CadnaOwie_Hooray_Aquifer_Extent.shp
