  • The National Base Map service provides seamless topographic colour mapping for the whole of Australia, including the outer islands of Norfolk, Lord Howe & Macquarie Islands, the external territories of Cocos (Keeling), Christmas, Heard and McDonald Islands and the Australian Antarctic Territory. The service consists of data sourced from Geoscience Australia, Australian Antarctic Division & OpenStreetMap. The data for Christmas Island has been sourced from the Christmas Island Edition 1 NATMAP Topographic Mapping dataset (1:30,000 scale). The data for Cocos (Keeling) Islands has been sourced from the Cocos (Keeling) Islands Edition 1 NATMAP Topographic Mapping dataset (1:25,000 scale). Vegetaion for the the Australian continent is an aggregated layer from ACLUMP (Australian Collaborative Land Use and Management Program). The topographic information was checked in 2008 using satellite imagery, and supplemented using other sources in 2009. Limited field checking has been undertaken for these data and therefore some information may not be accurate. Information and assistance was supplied by the Attorney General's Department (Territories of Australia) and Department of Environment, Water, Heritage and the Arts (Parks Australia). Geoscience Australia gratefully acknowledges contibutions to data content.) When viewing the map of mainland Australia beyond 1:100,000 scale, the data is derived from the Geoscience Australia GEODATA TOPO 250K product, except roads which are OpenStreetMap data, and in from 1:100,000 scale the data is derived from OpenStreetMap data ( © OpenStreetMap contributors). The suburbs layer is sourced from the Suburb 2018 and 2020 data, Australian Bureau of Statistics. The map portrays detailed graphic representations of features that appear on the Earth's surface. These features include cultural, hydrography, marine, transport, vegetation and relief themes. The SRTM data was acquired by NASA in February 2000 and was publicly released under Creative Commons licensing from November 2011 in ESRI Grid format. The SRTM DEM has quite different characteristics to DEMs derived by interpolation from topographic data. The SRTM data is derived from radar measurements that are dense (there is essentially a measurement at almost every grid cell) but noisy. The main processing of the SRTM DEM product has included: stripe removal, void filling and vegetation offset removal. Processing methods are further described in the 1 and 3 second SRTM Derived Products User Guide (Geoscience Australia, 2011). The bathymetry image used for this map is sourced from Natural Earth.

  • This service is produced for the National Map project. It provides seamless topographic greyscale mapping for the whole of Australia, including the external territories of Cocos (Keeling) Islands, Christmas Island, Norfolk Island and Lord Howe Island. The service consists of Geoscience Australia data at smaller scales and OpenStreetMap data is used at larger scales. The service contains layer scale dependencies.

  • This web service provides access to datasets generated by the North Australian Craton (NAC) Iron Oxide Copper Gold (IOCG) Mineral Potential Assessment. Two outputs were created: a comprehensive assessment, using all available spatial data, limiting data where possible to capture mineral systems older than 1500 ma, and; a coverage assessment, which is constrained to data that have no reliance on outcrop or age of mineralisation.

  • This service includes world bathymetry, elevation (hillshade), and satellite imagery data, and ocean, country, population and natural features. The information was derived from various sources, including Natural Earth and Landsat Imagery. It is a cached service with a Web Mercator Projection. The service contains layer scale dependencies.

  • Offshore Minerals Act (OMA 1994) - Mineral Blocks. This service displays the most recent realisation of the Mineral Blocks as defined under the Offshore Minerals Act 1994 (OMA 1994) as realised in GDA94. Block data extends beyond the area of operation of the OMA and includes areas of coastal waters and land within the constitutional limits of the States and Territories.

  • OPGGSA 2006 - Petroleum Blocks. This service displays the most recent realisation of the Petroleum Blocks as defined under Section 33 (3) of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGSA 2006) as realised in GDA94. Block data extends beyond the area of operation of the OPGGSA and includes areas of coastal waters and land within the constitutional limits of the States and Territories.

  • Analytical results and associated sample and analysis metadata from the analysis of minerals in earth material samples.

  • 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 service is produced specifically for the Northern Australia Project and may be removed or changes without notice. This web service shows land tenure in Western Australia and Queensland north of the Tropic of Capricorn and the whole of Northern Territory. This service uses PSMA 2015 land tenure data for Western Australia, and PSMA August 2016 for Northern Territory and Queensland.

  • This service provides access to hydrochemistry data (groundwater and surface water analyses) obtained from water samples collected from Australian water bores or field sites.
