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.

Melbourne 2007 LiDAR data was made up of several project areas that were funded by the Department of Sustainability and Environment, Victoria that results in the delivery of 1m DEM and 0.5m contours, captured and supplied by AAMHatch. The Port Phillip and Western Port LiDAR Project was acquired for several local government areas namely, Bayside (20 April 2007 and 1 May 2007, 1km tiles), Boorondara, Glen Eira, Kingston, Port Phillip and Stonnington. Brimbank City Council, inner suburbs including part of the CBD area, Yarra River and South Mornington Coast data is in 2km tiles captured between 20 April 2007 and 10 July 2007. The Melbourne - Geelong Corridor area was captured between 24 April 2007 and 29 July 2007 for an area of approximately 145 square kilometres in 2km tiles. The data has an overall horizontal accuracy of 35cm and a vertical accuracy has been confirmed at <10cm. The data are available as mass point files (ASCII, LAS, shp, MapInfo TAB) with a density of 0.8- 0.85 points per square metre and ESRI GRID files with 1m grid spacing and 0.5m inundation contours.

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).

These data are best suited to graphical applications. These data may vary greatly in quality depending on the method of capture and digitising specifications in place at the time of capture. Major island features have been included from the LOSAMBA coastline data capture around the Coral Sea area. 250K Specification Description - Island - An area of land fully surrounded by the sea.

The surface geology of Queensland ranges in age from Palaeoproterozoic to Recent. The oldest rocks largely occur in the Mount Isa and Georgetown Inliers in the northwest and central north of the state respectively. These rocks have undergone greenschist to amphibolite facies metamorphism and were extensively intruded by granite during the Mesoproterozoic. Metamorphics of Meso to Neoproterozoic age occur in the Coen Inlier in eastern Cape York, in the Hughenden-Charters Towers-Townsville region to the south and east of Georgetown, and also further south in the Anakie Inlier. During Cambrian to Ordovician times, extensive carbonate dominated, marine sedimentation took place in the Georgina Basin, West and southwest of Mount Isa. These rocks were subsequently faulted and gently folded prior to the Devonian, perhaps during the mid-Ordovician Thompson Orogeny. Silurian to Devonian marine sedimentation is preserved in the Hodgkinson and Broken River Basins in the north east of the state while similar aged, arc related deposits accumulated in the New England Orogen which occupies a 200 km wide coastal strip between Bowen and Brisbane in the southeast of the State. The Hodgkinson - Georgetown region and New England Orogen were extensively intruded by granite during Carboniferous to Permian times. Permian to Triassic sediments of the Galilee and Bowen Basins outcrop in the central east of the state while similar aged sediments accumulated to the east and southeast within the New England Orogen. Widespread sedimentation during the Jurassic to Cretaceous (Carpentaria, Eromanga, Mulgildie, Surat, and Laura Basins) blanketed large areas of older bedrock, particularly in the central, southern and south western parts of the state. Finally, Cainozoic cover units comprise approximately half the surface geology with sand plain (Czs), sand plain with dunes (Czd), colluvium (Qrc), alluvium (Qa), and Tertiary to Quaternary basalt flows comprising the major components. The data set was initially compiled from older regional data sets including those covering the Eromanga, Surat and Carpentaria-Karumba Basins. Extensive areas were recompiled using more recent 1:250 000 and 1:100 000 scale mapping, particularly in the Georgetown-Charters Towers-Ebagoola region, and also the area of the New England Orogen. The data set includes nearly 1800 named, informal or unnamed units.

The National Marine Bioregionalisation is a major scientific project headed by the National Oceans Office, designed to help define ecosystem boundaries in Australia's ocean territory. It brings together and illustrates the complexity and variability of marine environments and supports Australia's Oceans Policy commitment to an ecosystem-based approach to oceans management.

The surface geology of New South Wales comprises rocks ranging in age from the Palaeoproterozoic to recent. The oldest rocks are the strongly deformed and metamorphosed Willyama Supergroup of the Curnamona Craton in far western New South Wales. Neoproterozoic to Cambrian shallow marine to continental sediments and volcanics overlie the margin of the Curnamona Craton. The south-eastern part of New South Wales is dominated by the Palaeozoic sediments, volcanics and granites of the Lachlan Orogen. These rocks occur from the eastern Victorian border to the Cobar region and underlie the southern highlands. North-eastern New South Wales is underlain by the Palaeozoic to Mesozoic rocks of the New England Orogen. The Lachlan and New England Orogens are overlain by sedimentary basins of Permian to Recent age. Permian to Cretaceous sediments of the Sydney-Bowen, Gunnedah and Clarence-Moreton Basins overlie the two orogens in eastern New South Wales. Sediments of the Mesozoic Eromanga, Surat and Berri Basins occur in the north and west of New South Wales; and the Cainozoic Murray Basin covers the majority of the south-west of the state. The Cainozoic regolith units of New South Wales are represented in this dataset according to a simplified classification scheme which is being applied nationally at 1:1 000 000 scale. The dataset was generalised largely from the 2003 version of the New South Wales Department of Mineral Resources (NSWDMR) state digital geology dataset, comprising 1:250 000 to 1:100 000 scale mapping data. Some areas (denoted in the dataset metadata) have been recompiled from more recent mapping data sourced from NSWDMR. In other areas, such as the Broken Hill region and the Murray Basin region, 1:500 000 and 1:1 000 000 scale data was incorporated from published regional maps. Compilation of the seamless state dataset necessarily involved much edgematching of source datasets due to their varying ages and original compilation scales. Adjustment of some older geological datasets was made using geophysical data interpretation where particularly poor edgematching or spatial accuracy (± 1 km) was identified in source data.
