Lineage

Maintenance and Update Frequency: irregular

Statement: Geological mapping was compiled through integration of field mapping, aerial photograph interpretation, 250m line spaced airborne geophysics (magnetics and radiometrics), university studies and open file company reports. Mapping was digitised in Intergraph Microstation and ArcInfo from compilation sheets compiled onto 1:25,000 and 1:50,000 scale topographic film bases. Preliminary data was released in hardcopy and ArcInfo format in October 1994. Since then, considerable further editing has been performed in ArcInfo (under UNIX SunOS and Solaris) to create the current version. Conversion to MapInfo format uses Arclink software.
