  • The Marine Survey Multibeam Bathymetry Web Map Service contains the highest-resolution multibeam bathymetry grids available for download on Geoscience Australia's website. These bathymetry grids were collected over numerous multibeam survey programs conducted in Australian mainland and Antarctic waters by both Geoscience Australia and our collaborators. Layers are grouped by survey or region and where available include both the Geoscience Australia and vessel survey identification numbers that contributed to the bathymetry grids. Bathymetry grids have been rendered over a rainbow colour-ramp with minimum and maximum depth values unique for each survey. These values are specified in each survey's layer description. The resolution of each bathymetry grid is also specified in each survey's layer description

  • Web Map Service of Geoscience Australia's national geophysical grids for magnetics, gravity and radiometrics. The service also contains outlines and descriptions of the airborne geophysical surveys used to compile the magnetic and radiometric grids.

  • The Surface Geology web map service provides two seamless national coverages of Australian bedrock and surficial geology, compiled at 1:1 million scale (displays only at scales less than 1:1500000), and 1:2.5 million scale (displays only at scales greater than 1:1500000). It also contains 1:5 million scale geological regions and metamorphic geology. The service represents outcropping or near-outcropping bedrock units, and unconsolidated or poorly consolidated regolith material covering bedrock.

  • This web map service provides visualisations of datasets prepared for the Technology Investment Roadmap Data Portal. The service has been developed using various mineral deposit, mine location and industrial plant location datasets sourced from the Australia’s Identified Mineral Resources (2019), produced by Geoscience Australia (http://dx.doi.org/10.11636/1327-1466.2018)

  • The Tasselled Cap Wetness (TCW) percentage exceedance composite represents the behaviour of water in the landscape, as defined by the presence of water, moist soil or wet vegetation at each pixel through time. The summary shows the percentage of observed scenes where the Wetness layer of the Tasselled Cap transform is above the threshold, i.e. where each pixel has been observed as ‘wet’. Areas that retain surface water or wetness in the landscape during the dry season are potential areas of groundwater discharge and associated GDEs. The TCW exceedance composite was classified into percentage intervals to distinguish areas that were wet for different proportions of time during the 2013 dry season. Areas depicted in the dataset have been exaggerated to enable visibility.

  • The WOfS summary statistic represents, for each pixel, the percentage of time that water is detected at the surface relative to the total number of clear observations. Due to the 25-m by 25-m pixel size of Landsat data, only features greater than 25m by 25m are detected and only features covering multiple pixels are consistently detected. The WOfS summary statistic was produced over the McBride and Nulla Basalt provinces for the entire period of available data (1987 to 2018). Pixels were polygonised and classified in order to visually enhance key data in the imagery. Areas depicted in the dataset have been exaggerated to enable visibility.

  • AUSIMAGE Aerial Imagery Canberra 2014 is a web service of high resolution aerial imagery (10 cm to 18 cm) over Canberra and Queanbeyan, acquired in February and April 2014. AUSIMAGE Aerial Imagery is a data product of Jacobs Group (Australia) Pty Ltd, released by Geoscience Australia as a web map service under license agreement.

  • This web map service provides visualisations of in-service, large-scale battery installations connected to the National Energy Market (NEM) power system in eastern and south-eastern Australia. Data compiled from the Australian Energy Market Operator (AEMO).

  • This web map service provides location information and details about commodities exported from shipping ports around Australia. This dataset has been collated by Geoscience Australia from publicly available information as a guide only.

  • The annual offshore petroleum exploration acreage release is part of the government’s strategy to promote offshore oil and gas exploration. Each year, the government invites companies to bid for the opportunity to invest in oil and gas exploration in Australian waters. The 2020 acreage release consists of 42 areas offshore of the Northern Territory, Western Australia, Victoria and the Ashmore and Cartier Islands.
