Abstract
It was derived by the Bioregional Assessment Programme from Figure 7 of Nicol (2010). You can find a link to the parent datasets in the Lineage Field in this metadata statement. The History Field in this metadata statement describes how this dataset was derived.
The dataset shows the mapped extent of the Balook Formation.
Purpose
The Balook Formation is an important sand formation in the sedimentary sequence of the Gippsland Basin, providing a conduit for inter-aquifer connectivity.
Dataset History
The extent of the Balook Formation was digitised from the PDF map in Figure 7 of Nicol (2010) using the polygon construction tool within ArcMap 10.2. The source map was georeferenced prior to digitising using the layers TOPO2_5M_FRAMEWORKBOUNDARIES and TOPO2_5M_ROADS (GUID: 310c5d07-5a56-4cf7-a5c8-63bdb001cd1a) to select accurate control points.
