  • This dataset maps the geomorphic habitat environments (facies) for 36 South Australian coastal waterways. The classification system contains 12 easily identifiable and representative environments: Barrier/back-barrier, Bedrock, Central Basin, Channel, Coral, Flood- and Ebb-tide Delta, Fluvial (bay-head) Delta, Intertidal Flats, Mangrove, Rocky Reef, Saltmarsh/Saltflat, Tidal Sand Banks (and Unassigned). These types represent habitats found across all coastal systems in Australia. Most of the 36 coastal waterways have a "Modified" environmental condition (as opposed to "Near Pristine"), according to the National Land and Water Resources Audit definition.

  • 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  • This digital data package comprises all available 1:100 000 scale first edition and unpublished preliminary geological maps of the Mount Isa Inlier, Murphy Tectonic Ridge, South Nicholson Basin and southern McArthur Basin. It also includes parts of the Mount Drummond and Lawn Hill 1:250 000 sheets which have not been mapped at 1:100 000 scale. The complete data set covers 19 full, 5 combined and 4 part 100,000 scale map sheets. All faults within this area have been coded uniquely to facilitate metallogenic analysis. The data, currently version 2.1, can be downloaded and comprises either MapInfo or Arcinfo/Arcview formats. For Arcview, unique legends have been created for the geology layers of each individual dataset, uniform across the whole of the Mount Isa dataset.

  • Arcview GIS containing a regolith-landfrom map with associated site database. Most sites have a field photograph hot linked into the GIS. Complementary datasets include, digital elevation model and enhanced Landsat TM imagery.

  • This dataset maps the geomorphic habitat environments (facies) for 73 Tasmanian coastal waterways. The classification system contains 12 easily identifiable and representative environments: Barrier/back-barrier, Bedrock, Central Basin, Channel, Coral, Flood- and Ebb-tide Delta, Fluvial (bay-head) Delta, Intertidal Flats, Mangrove, Rocky Reef, Saltmarsh/Saltflat, Tidal Sand Banks (and Unassigned). These types represent habitats found across all coastal systems in Australia. The majority of near pristine estuaries in Tasmania are located in the south and west of the State and on Cape Barren Island, according to the Department of Primary Industries, Water and Environment.

  • The GIS database for the Broken Hill Managed Aquifer Recharge (BHMAR) project contains the spatial data associated with the project including interpreted products derived to identify groundwater resource and managed aquifer recharge targets in the Darling River floodplain study area. Themes include airborne electromagnetics (AEM), boreholes, surface topography (including LiDAR), geology and geomorphology, hydrology, hydrostratigraphy, hydrogeology and vegetation. The data is stored in an ArcGIS geodatabase in both vector and raster formats and metadata can be accessed using ArcCatalog.

  • This GIS dataset represents digital files accompanying the Index of Airborne Geophysical Surveys (14th edition) 2014, which presents a summary of specifications of open file surveys held in GA's National Airborne Geophysical Database. The product provides spatial coverage and metadata for all magnetic, radiometric and AEM surveys for which spatial information is available, current to 21 March 2014. The GIS dataset is useful for making maps showing the coverage of open file Australian airborne geophysical surveys.

  • This GIS dataset represents digital files accompanying the Index of Airborne Geophysical Surveys (13th edition) 2013, which presents a summary of specifications of open file surveys held in GA's National Airborne Geophysical Database. The product provides spatial coverage and metadata for all magnetic, radiometric and AEM surveys for which spatial information is available, current to 21 March 2013. The GIS dataset is useful for making maps showing the coverage of open file Australian airborne geophysical surveys.

  • This GIS dataset shows where Geoscience Australia (GA) has acquired regional seismic reflection data as a part of Australian Government's Onshore Energy Security Program (OESP) in collaboration with State and Territory geological surveys, AuScope and Australian National Seismic Imaging Resource (ANSIR). During 2006-2011 GA collected over 6,500 line kilometres of new world-class seismic reflection data within Australia for use by industry and government. This dataset is generated from files containing CDP (Common Depth Point) coordinates of all OESP seismic surveys. The CDP line is a curve of best fit through the midpoints between sources and receivers, which optimises the fold of the data while minimising the subsurface area of reflections contributing to each nominal CDP. Each trace (source-receiver pair) is allocated to the nearest CDP bin to its midpoint. The interval between each CDP traces is 20 metres.
