Depth to top of the interconnected Grant Group and Poole Sandstone aquifers

Point stratigraphic picks published in Mory (2010) were collated along with stratigraphic picks from groundwater bores available from the Western Australian government. These two data sets were combined and used to interpolate isopachs for the thickness and extent of stratigraphic units overlying the interconnected Grant Group and Poole Sandstone in the Fitzroy Trough Western Australia. The surface represents the depth to the top of the interconnected Grant Group and Poole Sandstone below the natural surface. The purpose of the data set was to derive a spatial understanding of the change in depth to the top of the interconnected Grant Group and Poole Sandstone aquifers. This was used to communicate the depth required to intersect the aquifers by drilling.
