  • 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

  • Outcrop geology was obtained directly from the following 1:250 000 map sheets: Marble Bar, Nullagine, Port Hedland and Yarrie. This dataset consists of both raster and vector data. Raster data which is unsigned 8 bit integer, can be viewed in Arc/Info, ArcView, MapInfo, ERMapper, ERViewer and ArcExplorer. Raster data which is 4 byte real data, can only be viewed and manipulated with an image processing package such as ERMapper.

  • Geomorphic banks were mapped in this study based on a GIS analysis of a 100 m bathymetry grid for the Great Barrier Reef produced by Beaman (2010). The bathymetric data were contoured at 5 m intervals and used to interpret the location of geomorphic bank features, defined as having at least one steep (i.e. greater than ~2 degrees) slope rising more than 15 m above the level of surrounding seafloor. All banks were digitised by hand aided using three-dimensional imagery. Bank polygons were created in ArcGIS with the base of slope taken as the outer edge of the bank. Mean bank elevation estimates thus include the bank slopes as well as planar bank-tops. Only banks occurring on the continental shelf of the Great Barrier Reef between the 20 and 200 m isobaths, and between the latitudes of 10 to 25° S were included.

  • The Christmas Island Geographic Information System (CIGIS) is a collection of spatial data, viewing and analysis tools dealing with Christmas Island. The data include orthophotography, topographic, mining, cultural and environmental features of the island. Compilation of data and its organisation into a GIS together with documentation was undertaken by the Australian Geological Survey Organisation (AGSO) at the request of the Territories Office, Department of Transport and Regional Services (DOTRS). The data are presented in both ESRI ArcView and ArcExplorer projects. The ArcView projects require a licensed copy of ArcView. ArcExplorer is a free viewer and is distributed with the Cocos GIS CD-ROM. Data are stored as ESRI shapefiles and therefore readily useable with most modern GIS applications. Data were received from a variety of custodians and in many cases had no accompanying documentation. Lack of documentation made it increasingly difficult for AGSO with interpretation, translation and documentation of data. AGSO has attempted to include metadata for all datasets to ANZLIC core metadata standards, but the value of this is limited by the poor initial documentation. In addition to limited documentation, many datasets had inconsistent spatial accuracy. The CocosGIS comprises four main CD-ROMs with additional CD-ROMs containing full-colour orthophotography. A hard-copy user guide is distributed with the main CD-ROM set.
