  • This service represents the National Digital Elevation Model (DEM) 1 Second Percentage Slope product, derived from the National DEM SRTM 1 Second. Slope measures the inclination of the land surface from the horizontal. Percent slope represents this inclination as the ratio of change in height to distance.

  • Geoscience Australia conducted a marine seismic survey (GA-0352) over various areas of the Gippsland Basin, between 5th of April to the 24th of April 2015, by the Gardline CGG vessel MV Duke. This service includes all the bathymetry data collected during the survey, with the data also available as a free download from the Geoscience Australia website. The aim of the survey was to acquire industry-standard precompetitive 2D seismic data, Multi-beam echo-sounder (MBES) and sub-bottom profiling (SBP) data to support an assessment of the CO2 storage potential of the basin. The survey, undertaken as part of the Department of Industry and Science's National CO2 Infrastructure Plan (NCIP), aimed to identify and characterise indicators of natural hydrocarbon or fluid seepage that may indicate compromised seal integrity in the region. The data collected during this survey will enhance sequence stratigraphic studies in the Gippsland Basin that provide constraints on the most suitable areas for storage of CO2 and help to identify potential CO2 storage reservoirs.

  • The Houtman Sub basin 2D seismic survey web service display seven seamless bathymetry grids of 15m (shallow water) and 25m (deep water) resolution.

  • This Service represents the 25 metre Digital Elevation Model (DEM), with national coverage. It is derived from merged LiDAR and various projects. New data will be added to the service as it becomes available.

  • This web service provides access to the Geoscience Australia (GA) ISOTOPE database containing compiled age and isotopic data from a range of published and unpublished (GA and non-GA) sources. The web service includes point layers (WFS, WMS, WMTS) with age and isotopic attribute information from the ISOTOPE database, and raster layers (WMS, WMTS, WCS) comprising the Isotopic Atlas grids which are interpolations of the point located age and isotope data in the ISOTOPE database.

  • This web service provides access to gridded data produced by Geoscience Australia from studies of Australian groundwater and hydrogeological systems.

  • The Australian Bathymetry and Topography web service includes the topography of Australia and the bathymetry of the adjoining Australian Exclusive Economic Zone. The area selected does not include data from Australia's marine jurisdiction offshore from the Territory of Heard and McDonald Islands and the Australian Antarctic Territory. The 2009 bathymetry data were compiled by Geoscience Australia from multibeam and single beam data, and along with the topography (onshore) data, was derived from multiple sources. As per the 2005 grid, the 0.0025 dd resolution is only supported where direct bathymetric observations are sufficiently dense (e.g. where swath bathymetry data or digitised chart data exist) (Webster and Petkovic, 2005). In areas where no sounding data are available (in waters off the Australian shelf), the grid is based on the 2 arc minute ETOPO (Smith and Sandwell, 1997) and 1 arc minute ETOPO (Amante and Eakins, 2008) satellite derived bathymetry. The 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).

  • This web service provides access to groundwater raster products for the Upper Burdekin region, including: inferred relative groundwater recharge potential derived from weightings assigned to qualitative estimates of relative permeability based on mapped soil type and surface geology; Normalised Difference Vegetation Index (NDVI) used to map vegetation with potential access to groundwater in the basalt provinces, and; base surfaces of basalt inferred from sparse available data.

  • This web service contains the Casey Station Bathymetry survey that displays one seamless bathymetry grid of 1m resolution. The GA-0348 survey, acquired by Geoscience Australia, Royal Australian Navy and Australian Antarctic Division (AAD) on-board the Research Vessel Howard Burton from the 23rd of December 2014 to the 27th of January 2015. Further details of the data lineage can be found with the associated database.

  • This web service contains map layers and coverages for machine learning models, using raster datasets which include radiometric grid infill, cover depths and conductivity. All grids have been converted to cloud-optimised GeoTIFF (COG) format for use and delivery from an cloud-based object store (AWS s3).
