This web service delivers metadata for onshore active and passive seismic surveys conducted across the Australian continent by Geoscience Australia and its collaborative partners. For active seismic this metadata includes survey header data, line location and positional information, and the energy source type and parameters used to acquire the seismic line data. For passive seismic this metadata includes information about station name and location, start and end dates, operators and instruments. The metadata are maintained in Geoscience Australia's onshore active seismic and passive seismic database, which is being added to as new surveys are undertaken. Links to datasets, reports and other publications for the seismic surveys are provided in the metadata.

The Historical Bushfire Boundaries service represents the aggregation of jurisdictional supplied burnt areas polygons stemming from the early 1900's through to 2022 (excluding the Northern Territory). The burnt area data represents curated jurisdictional owned polygons of both bushfires and prescribed (planned) burns. To ensure the dataset adhered to the nationally approved and agreed data dictionary for fire history Geoscience Australia had to modify some of the attributes presented. The information provided within this service is reflective only of data supplied by participating authoritative agencies and may or may not represent all fire history within a state.

This service has been created specifically for display in the National Map and the chosen symbology may not suit other mapping applications. The Australian Topographic web map service is seamless national dataset coverage for the whole of Australia. These data are best suited to graphical applications. These data may vary greatly in quality depending on the method of capture and digitising specifications in place at the time of capture. The web map service portrays detailed graphic representation of features that appear on the Earth's surface. These features include the administration boundaries from the Geoscience Australia 250K Topographic Data, including state forest and reserves.

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 service is for the 'OZTemp Interpreted Temperature at 5km Depth' image of Australia product. It includes an interpretation of the crustal temperature at 5km depth, based on the OZTemp bottom hole temperature database and additional confidential company data.

This service includes well geothermal temperature and location, extracted (from the OZTemp database), and used to create the 'OZTemp Interpreted Temperature at 5km Depth' image of Australia.

This service provides Estimates of Geological and Geophysical Surfaces (EGGS). The data comes from cover thickness models based on magnetic, airborne electromagnetic and borehole measurements of the depth of stratigraphic and chronostratigraphic surfaces and boundaries.

World Bathymetry Base Map tile cache. The service includes world bathymetry data, and ocean, country, population and natural features. The information was derived from various sources, including Natural Earth and National Geophysical Data Center (NGDC) ETOPO2 Global 2 Elevations from the September 2001 data. The service contains layer scale dependencies.

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.

3D seismic survey polygon area. The data within this layer only contains high level information regarding the individual surveys, not the actual survey. NOPIMS data is supplied by the petroleum industry. NOPIMS data is only offshore petroleum that belongs to the Commonwealth. A two dimensional (3D) seismic survey is a method of exploration used to capture seismic data beneath Earth's surface. 3D seismic provides continuous information of the subsurface within the extent of the survey. transect line of information in the survey. This method sends energy waves into the Earth to detect changes in the subsurface geology. The rock formations in the subsurface geology reflect the waves back to detector, where they are captured over the desired timeframe and converted into a seismic image. Depending on the age the survey was conducted will depend on the method used to capture the information. Older records more likely used explosives to capture seismic data whereas newer surveys use compressed air.
