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.

The data currently held for bathymetry has been extracted from the GEBCO (General Bathymetric Chart of the Oceans) produced by the Natural Environment Research Council (UK).

The dataset and accompanying animation show the seismic p-wave velocity of the crust and upper mantle in Australia through a series of slices at 1 km depth intervals from the surface down to 55 km. The velocity data is derived from velocity depth curves interpreted from seismic refraction surveys.

Field descriptions include, information on lithology, stratigraphic unit, alteration, magnetic susceptibility, hand-held radiometric spectrometer response and structural measurements.OZROX has over 100 000 field sites derived mainly from AGSO - Geoscience Australia's mapping, with additional contributions from Universities and State Surveys.

These data represent the grid of the Magnetic Anomaly Map of Australia (third edition). This grid was compiled from 9 million line-kilometres of TMI data held in the National Airborne Geophysics Database. The data were collected in surveys conducted by Geoscience Australia and by airborne geophysical companies operating under contracts to Geoscience Australia and State and Territory Geological Surveys, either separately or in joint projects. Data from a number of other surveys, carried out for private companies, were acquired by Geoscience Australia. These datasets contain anomalies with wavelengths as small as 800 m.

The two versions of the printed Topographic Map Index are: - the 1:100,000 / 1:250,000 Topographic Map Index - the 1:50,000 Topographic Map Index Topographic map indexes are also available as digital data. Maps are listed by name on the back of the index. The 1:50,000 Index also lists availability of Orthophoto Map (OPM) and Topographic Line Map (TLM) for available 1:50,000 maps. Both indexes are available in printed form from your nearest topographic map retailer or from the Geoscience Australia Sales Centre. You can also download PDFs of each index. Note: To print these PDFs at 100% requires an A0 printer. They are best for viewing on-screen. For new maps which may have been released after these indexes were published, please refer to the new releases page or use the Product Search tool.

This digital dataset is a compilation of the best digital geological map data available in September 1996, drawn mostly from Department of Mines and Energy Queensland (DME) and AGSO published 1:100k, 1:250k, 1:1mil and 1:2.5mil scale geological maps, supplemented by Cainozoic geology from AGSO/(Cape York Peninsula Land Use Strategy) CYPLUS regolith landform and coastal zone maps. The 45 different map units reflect logical age/lithology groupings selected to provide a compromise between readability in hardcopy at 1:1mil scale and a useful amount of information. Internal boundaries of units grouped together were eliminated but the identity of mapped units within each polygon has been added to info tables. The digital dataset was constructed as a basis for hardcopy map products - a 1:1mil scale geological map and a 1:3mil scale geological atlas to accompany AGSO Bulletin 240 - not as a digital product per se. Subsequently, in 2001, the dataset was upgraded to serve as part of a new 1:1mil scale outcrop geology map of Australia. This work comprised QA/QC of linework and attributes, and the addition of polygon constituent information.
