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 Vlaming Sub-Basin CO2 Storage Potential Study web service includes the datasets associated with the study in the Vlaming Sub-basin, located within the southern Perth Basin about 30 km west of Perth. The data in this web service supports the results of the Geoscience Australia Record 2015/009 and appendices. The study provides an evaluation of the CO2 geological storage potential of the Vlaming Sub-basin and was part of the Australian Government's National Low Emission Coal Initiative.

Colour and greyscale images have been generated at several resolutions (pixel sizes 860m, 2km, 4km, 10km) and these are digital pictoral representations of the 30 arc second bathymetric point grid of the Australian region released in 1998 and a sub sampled version of the GEODATA NINE SECOND DEM, 1996 which is copyright, Commonwealth of Australia, AUSLIG. These images depict the continental margin morphology, and are suitable for use in diverse applications, such as resource management, oceanographic modelling and fisheries studies. The original gridded bathymetry model for the Australian continental margin was generated from 14,000,000 data points gathered from numerous data sources and compiled by Cameron Buchanan at the Australian Geological Survey Organisation, as part of the Continental Margins Program. The database is a 30-arc-second model that can display undersea features as small as 900 metres. The model has been compiled over several years from hundreds of marine surveys. It includes data acquired by industry and foreign agencies, and from over 200 days of modern deep-water seafloor swath-mapping surveys. In some areas not covered by marine surveys, it incorporates bathymetry data derived from satellite measurements. The raw ASCII data is available on CD Titled "Bathymetric 30 arc second grid of the Australian Region" (1998) from the AGSO sales centre. NOTE : This product does not contain topography.

The GA CCC Impact Analysis Map products are a series of ESRI map templates used to map natural and man-made hazard events. They have been designed specifically to support GA's collaboration with EMA to provide situational awareness and exposure information for CCC Operations and Recovery.

This dataset spatially represents the OZCHRON database of physical age determinations of Australian rocks, and the radiogenic isotope ratios used in determining the ages. Rocks dated are mainly from Australia, but the database does include some ages from rocks in Antarctica and Papua New Guinea. This OZCHRON dataset comprises period ages of samples derived using theRb-Sr, SHRIMP, U-Pb, and Sm-Nd age determination methods.
