In order to do this, we provide high-quality data sets such as this GIS, which provides different views of the same area, allowing correlation, comparison, and analysis at a broad scale across the entire North Pilbara. The advantage of this GIS is that it packages Geoscience Australia's primary data holdings for the entire region into a convenient digital package that can be manipulated and integrated with proprietary data in standard mapping applications. The North Pilbara GIS provides industry with a decision-making context, or wide-spaced framework. The lack of context is due the fact that industry commonly only have restricted data holdings over their leases. Therefore, regional synthesis data sets provide a context and framework for exploration decisions made on more spatially limited data. The North Pilbara GIS provides many new digital data sets, including a number of variations of the magnetics, gravity, and gamma-ray spectrometry. A solid geology map, and derivative maps, mineral deposits, geological events, and Landsat 5-TM provide additional views. This data set complements the 1:1.5 Million scale colour atlas (announced in June-July issue 58 of AusGeoNews). This provision of a regional digital data set will be an invaluable tool for exploration companies making comparative, correlative, and analytical decisions on the prospectivity of the North Pilbara. Just a few of the new aspects of the GIS include: the under cover shape of prospective rocks with a new digital solid geology map; all the images generated by the project (magnetics, gravity, Landsat, and radiometrics); the imaging of several large shear zones, and complexity in granites; compilation of geochemistry and geochronology; a new chemical map based on radiometrics; identification of the source regions of transported regolith This map has been produced as a GeoPDF, which is an extension to the standard PDF file format viewed using Adobe Acrobat Reader. Layers can be turned off and on to customise the view of the data, similar to using Geographic Information System tools. In addition, GeoPDF maps are georeferenced to be compatible with other coordinated geographic data. Coordinate locations and distances can be retrieved automatically.
