This service represents a combination of two data products, the DEM_SRTM_1Second dataset and the Australian_Bathymetry_Topography dataset. This service was created to support the CO2SAP (Co2 Storage application) Project to create a transect elevation graph within the application. This data is not available as a dataset for download as a Geoscience Australia product. The DEM_SRTM_1Second service represents the National Digital Elevation Model (DEM) 1 Second product derived from the National DEM SRTM 1 Second. The DEM represents ground surface topography, with vegetation features removed using an automatic process supported by several vegetation maps. eCat record 72759. The Australian_Bathymetry_Topography service describes the bathymetry dataset of the Australian Exclusive Economic Zone and beyond. Bathymetry data was compiled by Geoscience Australia from multibeam and single beam data (derived from multiple sources), Australian Hydrographic Service (AHS) Laser Airborne Depth Sounding (LADS) data, Royal Australian Navy (RAN) fairsheets, the General Bathymetric Chart of the Oceans (GEBCO) bathymetric model, the 2 arc minute ETOPO (Smith and Sandwell, 1997) and 1 arc minute ETOPO satellite derived bathymetry (Amante and Eakins, 2008). Topographic data (onshore data) is based on the revised Australian 0.0025dd topography grid (Geoscience Australia, 2008), the 0.0025dd New Zealand topography grid (Geographx, 2008) and the 90m SRTM DEM (Jarvis et al, 2008). eCat record 67703. IMPORTANT INFORMATION For data within this service that lays out of the Australian boundary the following needs to be considered. This grid is not suitable for use as an aid to navigation, or to replace any products produced by the Australian Hydrographic Service. Geoscience Australia produces the 0.0025dd bathymetric grid of Australia specifically to provide regional and local broad scale context for scientific and industry projects, and public education. The 0.0025dd grid size is, in many regions of this grid, far in excess of the optimal grid size for some of the input data used. On parts of the continental shelf it may be possible to produce grids at higher resolution, especially where LADS or multibeam surveys exist. However these surveys typically only cover small areas and hence do not warrant the production of a regional scale grid at less than 0.0025dd. There are a number of bathymetric datasets that have not been included in this grid for various reasons.

Mean monthly and mean annual maximum, minimum & mean temperature grids. The grids show the temperature values across Australia in the form of two-dimensional array data. The mean data are based on the standard 30-year period 1961-1990. Gridded data were generated using the ANU (Australian National University) 3-D Spline (surface fitting algorithm). As part of the 3-D analysis process a 0.025 degree resolution digital elevation model (DEM) was used. The grid point resolution of the data is 0.025 degrees (approximately 2.5km). Approximately 600 stations were used in the analysis over Australia. All input station data underwent a high degree of quality control before analysis, and conform to WMO (World Meteorological Organisation) standards for data quality.

These datasets are a subset of the mosaic of Australian Landsat MSS images of Australia. ldsatmss.bil is a 500m pixel Lambert Conformal Conic projected dataset. ldsatmssdd.bil is a 0.0048 degree geographic projected dataset. NOTE The original image is located in the corporate storage system at /d/geo/store/data/image/landsat_mss/aus_mosaic. In this directory there is extensive documentation (OVERVIEW.TXT) which describes all contents.

The first edition ACE - Australian Continental Elements dataset is a GIS representation of the lithosphere fabrics of the Australian plate, interpreted from linear features and associated discontinuities in the gravity anomaly map of continental Australia (Bacchin et al., 2008; Nakamura et al., 2011) and the global marine gravity dataset compiled from satellite altimetry (Sandwell & Smith, 2009). It should be used in context with these input data sources, at scales no more detailed than the nominal scale of 1:5 000 000.

This project is based on the recognition that combinations of specific granite types and distinctive host rocks tend to be associated with certain types of Au, Cu, Zn, Pb, Sn and W mineralisation. Rarely is Proterozoic mineralisation hosted by granites themselves, for the most part being hosted in the country rock, often three or more kilometres from the nearest known granite. There is an apparent host rock control on the deposition of metals: this can be both compositional and also controlled by the competency of the host lithologies. This compositional host rock control has been documented by Stuart-Smith et al. (1993 - Geology and mineral deposits of the Cullen Mineral field, AGSO Bull. 229) for the Pine Creek Inlier and noted in the eastern Mount Isa Inlier by Wyborn and Heinrich (1993 - The relationship between late-tectonic felsic intrusives and Cu-Au mineralisation in the Eastern Fold Belt, Mount Isa Inlier, Trans Royal Soc Edinburgh, Earth Sci, 83, 201-209). This project collated data on the Proterozoic granites and their comagmatic volcanics, the mineralogical composition of the rocks that they intrude and briefly assessed the style and type of mineralisation present within 5 kms of an outcrop of granite. All data collated in the reports is built into the accompanying GIS, and essentially each item listed in the report is converted into a searchable item within the GIS. This project has aimed to provide the data and interpretations to show the following: 1) Which Proterozoic granites have metallogenic potential, 2) What commodities they are likely to be associated with, and 3) Where the better host rocks are located that are likely to host potential mineralisation. <p>Related material<a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=33388">The metallogenic potential of Australian Proterozoic granites.

This dataset provides the spatially continuous data of the seabed sand content (sediment fraction 63-2000 mm) expressed as a weight percentage ranging from 0 to 100%, presented in 0.01 decimal degree resolution raster format. The dataset covers the Australian continental EEZ, including seabed surrounding Tasmania. It does not include areas surrounding Macquarie Island, and the Australian Territories of Norfolk Island, Christmas Island, and Cocos (Keeling) Islands or Australia's marine jurisdiction off of the Territory of Heard and McDonald Islands and the Australian Antarctic Territory. This dataset supersedes previous predictions of sediment sand content for the Australian Margin with demonstrated improvements in accuracy. Accuracy of predictions varies based on density of underlying data and level of seabed complexity. Artefacts occur in this dataset as a result of insufficient samples in relevant regions. This dataset is intended for use at national and regional scales. The dataset may not be appropriate for use at local scales in areas where sample density is insufficient to detect local variation in sediment properties. To obtain the most accurate interpretation of sediment distribution in these areas, it is recommended that additional samples be collected and interpolations updated.

This folder contains the reports and supporting digital datasets from four geological studies published by SRK (later FrOGTech) consultants, between 2001 and 2007. Known as the OZ SEEBASE Compilation (Structurally Enhanced View of Economic Basement), the studies interpreted the three dimensional character of Australian sedimentary basins and their basement.
