  • The Surface Hydrology Points (Regional) dataset provides a set of related features classes to be used as the basis of the production of consistent hydrological information. This dataset contains a geometric representation of major hydrographic point elements - both natural and artificial. This dataset is the best available data supplied by Jurisdictions and aggregated by Geoscience Australia it is intended for defining hydrological features.

  • The GIS is based on the "Mount Isa Inlier and Environs" 1:500 000 scale map (published in 1987), which was digitised and verified against geochemical and mineral deposit point data. A series of interpretative geological and geochemical coverages were derived from these map data and point datasets such as ROCKCHEM, OZCHRON, and MINERAL DEPOSITS. Geophysical byte images provide broad regional views showing the concealed extent of the province.

  • This map is designed to show broad regolith-landform units, giving a regional overview of the main regolith types and their associated landforms.Included are the author's detailed Explanatory Notes to the map.

  • The digital dataset combines data from the Oracle ozchron, sites, and rocks tables and is presented as shapefiles and mapinfo files for the rubidium-strontium, conventional uranium-lead and samarium-neodymium geochronology themes. This dataset package will eventually include the uranium-lead shrimp data, and is intended to be updated on a regular basis until the project is completed.

  • Interpretation report with SAR images across the Great Australian Bight region. Interpretation of anomalies including classification of natural hydrocarbon seepage; basic geographic, well location and seismic data coverages; images of bathymetric, gravimetric and magnetic data; integration of seepage interpretation with geology. Sale prices are listed on the marketing flyer and controlled by the established contractual arrangements, file 1999/743 and 98/580

  • The integrated spatial database of geological, geophysical, geochemical and cultural data. Provides users with means of integrating and analysing data for mineral exploration and research. The area covered by GIS encompasses Broken Hill and Euriowie Blocks and comprises six 1:100 000 mapsheets; the Corona, Fowlers Gap, Broken Hill, Taltingan, Redan and Thackaringa.

  • This user guide describes the important instructions for using the Tasmanian Extreme Wind Hazard Standalone Tool (TEWHST). It aims to assist the Tasmanian State Emergency Service (SES) to view the spatial nature of extreme wind hazard (and how it varies depending on the direction of the extreme wind gusts). This information indicates detailed spatial texture for extreme hazard, which can provide guidance for understanding where the local-scale hazard (and impact) is expected to be the greatest for any particular event depending on the intensity and directional influence of the broad-scale severe storm. The tool provides spatial information at the local scale (25 metre resolution) of the return period extreme wind hazard (3-second gust at 10 metre height; variation with direction) where the broad-scale regional hazard is provided by the Australian and New Zealand Wind Loading Standard (AS/NZS 1170.2, 2002).

  • The Cadastral dataset is the spatial representation of property boundaries and descriptions in the Barcaldine, Charters Towers, Flinders, Longreach and Winton local government areas. It is a fundamental reference layer for spatial information systems in Queensland. This is a complete extract from the Digital Cadastral Database (DCDB). Updates to this cadastre in 2012 will be released on the following dates: January 15 and 29 - February 12 and 26 - March 11 and 25 - April 8 and 22 - May 6 and 20 - June 3 and 17 - July 1, 15 and 29 August 12 and 26 - September 9 and 23 - October 7 and 21 - November 4 and 18 - December 2, 16 and 30. In 2013 the 1st release date will be January 13.

  • The Perth 1:1M sheet covers an area underlain by Archaean rocks of the western Yilgarn Craton, adjacent, abutting or onlapping Proterozoic rocks such as the Northampton Block, and Phanerozoic rocks of the Perth Basin. The aeromagnetic interpretation provides most information on the distribution of Archaean rocks as these rocks are generally moderately to highly magnetised with reasonable variation of magnetisation. Adjacent Perth Basin sediments are poorly magnetised and spatially associated magnetic anomalies are attributed to underlying Proterozoic rocks. The Archaean rocks are subdivided into undivided gneiss-migmatite-granite (Agmg), banded gneiss (Agn), sinuous gneiss (Anu), greenstone (Aa), and granite plutons (Ag). Where important relative differences in magnetisation are mapped, the geophysical map units include the suffixes _h (high), _m (medium), _l (low) and _r (remanent) for the level of magnetisation. Dykes, faults, and unassigned small intrusives are also mapped. Large Archaean domains equivalent to geologically defined Provinces are also defined including Murchison, Toodyay- Lake Grace, Southwest, Southern Cross and Yeelirrie domains.

  • The NGMA Cooper-Eromanga Basins project is a co-operative undertaking between the agencies of the Commonwealth and Queensland, South Australia, New South Wales and Northern Territory governments. The aims of the project are to provide uniform regional data sets and to develop an understanding of the hydrocarbon generation potential of the Cooper and Eromanga Basins. This product provides an interactive environment in a GIS format where gas and oil show data, oil geochemistry data and geological data can be readily interrogated using a project-designed graphical interface
