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.

This data package is an archive of geospatially located and other digital geological and geophysical data covering the Tennant Inlier in the Northern Territory, a portion of the North Australia Project undertaken to understand elements within the North Australia Craton and its boundaries. It includes digital geospatial data and/or images for a number of regional scale, 1:250 000 scale and 1:100 000 scale geological map sheets, mineral locations, geophysical images, company drill hole and rock chip locations, company and Geoscience Australia geochemistry, and other regional themes. It also includes geophysical gravity data acquired by the project in the Tennant Inlier, including an ERMapper data set.

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.

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.

An integrated package comprising geological, structural, geophysical, geochronological and geochemical data. The GIS encompasses the outcropping and covered portions of Palaeoproterozoic and Mesoproterozoic rocks straddling the NSW-SA border (the Broken Hill, Euriowie, Olary, Mount Painter and Mount Babbage Inliers). The GIS features recent data collected by the Broken Hill Exploration Initiative.

The "Surface geology of Australia 1:1 000 000 scale, Victoria, 2nd edition" dataset is modified from the 1:1 000 000 scale "Victoria 1:1 000 000 Geology" map published in 1999 by the Geological Survey of Victoria. Modifications are mainly in the classification of all granitoid intrusions which were previously unnamed, and in the classification of Cainozoic regolith stratigraphy. The 1999 Victorian state data has been merged with the 1:1 000 000 "Geology of the Murray Basin" (BMR, 1991) dataset, primarily to achieve consistency in units across the Murray Basin in Victoria, South Australia and New South Wales. The geology of Victoria consists of a wide range of sedimentary, igneous and some metamorphic rocks. The oldest rocks are Cambrian clastic sedimentary rocks in the Glenelg River area, and greenstones along Moyston, Avoca, Heathcote and Governor faults. Most Cambrian rocks are metamorphosed to low-medium grade. The Middle(?) Cambrian Nargoon Group consists of the Glenthompson Sandstone and undated and undifferentiated metasedimentary rocks between the Yarramyljup and Escondida faults in western Victoria. The Late Cambrian St Arnaud Group and interpreted lateral equivalents, including marine turbiditic sandstone, mudstone, and shale, crop out between the Moyston and Avoca faults in the western part of the state. The Ordovician Castlemaine Supergroup, which occurs mostly between the Avoca and Heathcote faults in central-western Victoria, is a sequence of marine turbiditic sandstone, mudstone, black shale, and minor granule conglomerate. These rocks host the important Bendigo-Ballarat gold fields. Ordovician sediments in northeast Victoria (northeast of the Governor Fault) consist of the turbiditic sequences of the Adaminaby, Bendoc, and Kiandra groups. Silurian to middle Devonian clastic sedimentation in central Victoria between the Avoca and Governor faults is represented by the very thick Murridindi Supergroup of mainly siltstone and sandstone. Conglomerate is a minor component, and limestone rare. Late Silurian to Early Devonian clastic sediments and limestones occur in scattered outcrop areas in eastern Victoria (e.g., Wentworth, Barmouth, Mt Tambo, Buchan, and Errinundra groups). Devonian felsic volcanic rocks occur across the state. Some Cambrian and Ordovician granitic rocks are mapped in western Victoria in the Glenelg River area. Silurian granitic rocks occur in the east of the state and Early Devonian granitic rocks occur east of the Governor Fault and west of the Heathcote Fault. Middle to Late Devonian granitic rocks occur mainly in central Victoria. Much of the Late Devonian Avon Supergroup of clastic sedimentary rocks outcrop in central-east Victoria, although some occur in far east of the state. Some early Carboniferous clastic sediments (e.g., the Boorhaman Conglomerate) occur in the northeast of the state. Permian clastic sediments such as the Wild Duck Formation and equivalents, comprising glaciomarine and fluvial diamictite, sandstone, mudstone and conglomerate, occur in central and western Victoria. The Triassic Mt Leinster Igneous Complex of granite, syenite, trachyte and volcaniclastic sediments are found in northeast Victoria. Jurassic trachyte lavas, (e.g. the Coleraine Trachyte), occur in far west of the state. The Cretaceous Otway Group of fluvial volcaniclastic arkosic sandstone and mudstone occurs in the southern part of the state and extends offshore into Bass Strait. Palaeocene to Oligocene basaltic lavas and associated pyroclastics and fluvial sediments (Older Volcanics) occur in scattered outcrop areas in the southwest part of the state, while Holocene to Miocene lavas flows and cinder cones (Newer Volcanics) occur in large areas of the southwest part of the state.
