Brief descriptionThe product comprises digital outcrop geology and interpreted basement geology layers in ArcInfo, MapInfo and ArcView formats. The data were compiled from geological mapping of the Marsden 100K sheet from 1995 to 1999 by AGSO and the NSW Geological Survey under the NGMA. The data layers are a subset of the Forbes 250K sheet GIS data package.
LineageGeological mapping was compiled through integration of field mapping, aerial photograph interpretation, 400m line spaced airborne geophysics (magnetics and radiometrics), university studies and open file company reports. Mapping was scanned and digitised in Intergraph Microstation and Arc/Info from compilation sheets compiled on to 1:50,000 scale topographic film bases. Preliminary data was released in hardcopy in April 1999. Since then, considerable further editing has been performed in Arc/Info to create the current version. Data was converted to MapInfo and ArcView formats from Arc/Info.
