  • Data collected from Geodetic GPS observation campaigns over the last 15 years. This data set is from non-continuous GPS sites. It is a combination of surveys undertaken by Geoscience Australia, State collaborators and international collaborators.

  • The collection supports the compilation of national mineral resource and production statistics, and mineral prospectivity analysis. The collection includes the OZMIN database (Australian mineral deposit descriptions including geological, resource and production data); the MINLOC database (mineral occurrence locations sourced from Geoscience Australia and state and territory geological surveys); supporting GIS datasets (eg,mineral prospectivity datasets, ports, power stations); maps and reports.

  • Digital Elevation Model data record the terrain height variations from the processed point-located data recorded on an airborne geophysical survey. The aircraft altimeter data records the height of the aircraft above the ground and the aircraft GPS records the height of the aircraft above the ellipsoid. Subtracting the two values enables the height of the terrain beneath the aircraft relative to the ellipsoid to be calculated. This ellipsoidal terrain height is corrected for the variation between the ellipsoid and the geoid (the n-value correction) to produce terrain heights relative to sea level.

  • This Dataset has been collected over many decades for datum development and local monitoring purposes. It consists of measured angles, distances and height differences between monumented survey marks.

  • These data are the time series seismograph, hydroacoustic and infrasound data recorded from Australian National Seismograph Network (ANSN) observatories in Australia, islands in the Pacific, Southern and Indian Ocean's and the Australian Antarctic Territory. ANSN observatories include facilities operated by Geoscience Australia in collaboration with other international agencies. These data are acquired for the purpose of the detection and location of earthquakes and tsunamigenic events within the Australian continent and its surrounds. The dataset is also used to meet a subset of Australia's obligations to the Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO) to fulfil Australia's commitment to nuclear explosion monitoring. The seismic waveform data records seismic events to allow for the detection, location estimation (position and depth) and magnitude of earthquakes of magnitude of 3.0 or greater anywhere in Australia. Seismic (Digital). Seismograms (Physical plots (paper & film) and Digital Scans).

  • Geoscience Australia is responsible for the records and custody of Commonwealth aerial photography, acquired since 1928 up to the most recent analogue film capture in mid-1990s. Subsequent comparable information is available in the form of satellite imagery or direct digital aerial image capture. The majority of the landmass of Australia is covered by black and white photography at 1:80,000 scale. The near complete coverage was undertaken three times, in 1950s, 1960s and 1980s. Metadata about aerial photo surveys is recorded as flight diagrams on 1:250,000, 1:100,000 & 1:50,000 maps showing the approximate aircraft flight paths, selective depiction of photo centres, and other survey parameters. <b>Value:</b> Aerial imagery can be used to study change over time for land use, vegetation, environmental quality, etc. <b>Scope: </b>Images in the collection have been acquired since 1928 up to the most recent analogue film capture in mid-1990s.

  • Data collected from the Australian Regional Global Navigation Satellite System (GNSS) network, AuScope network and other GNSS observatories located around the world over the last 15 years.

  • The MARine Sediment (MARS) database contains detailed information on seabed sediment characteristics for samples collected from Australia's marine jurisdiction, including the Australian Antarctic Territory. It is an important scientific resource that includes sediment properties from seabed and sub-seabed samples spanning coastal, continental shelf and deep sea locations. Analytical properties include grain size, carbonate content, mineralogy, geochemical properties and age determinations. MARS currently holds approximately 100,000 sample records and new data are being added as they become available. Please contact us at ausseabed@ga.gov.au if you wish to contribute marine sediment data to the MARS database.

  • The National Spectral Database (NSD) houses data from Australian remote sensing scientists. The database includes spectra covering targets as diverse as mineralogy, soils, plants, water bodies and various land surfaces.<br /> Currently the database holds spectral information from multiple locations across the country and as the collection grows in spatial / temporal coverage, the NSD will service continental scale validation requirements of the Earth observation community for satellite-based measurements of surface reflectance. <b>Value:</b> Curated spectral data provides a wealth of knowledge to remote sensing scientists. For other parties interested in calibration and validation (Cal/Val) of surface reflectance products, the Geoscience Australia (GA) Cal/Val dataset provides a useful resource of ground-truth data to compare to reflectance captured by Landsat 8 and Sentinel 2 satellites. The Aquatic Library is a robust collection of Australian datasets from 1994 to present time, primarily of end-member and substratum measurements. The University of Wollongong collection represents immense value in end-member studies, both terrestrial and aquatic. <b>Scope:</b> The NSD covers Australian data including historical datasets as old as 1994. Physical study sites encompass locations around Australia, with spectra captured in every state. <b>Data types:</b> - Spectral data: raw digital numbers (DN), radiance and reflectance.  - From spectral bands VIS-NIR, SWIR1 & SWIR2: wavelengths 350nm - 2500nm collected with instruments in the field or lab setting.

  • <p>The Australian Stratigraphic Units Database (ASUD) is the national authority on stratigraphic names in Australia. It originated as the National Register of Stratigraphic Names in 1949. The register was originally set up to help geoscientists adhere to the then newly created Australian Code of Stratigraphic Nomenclature (Lenz, et al, 1996). All information was held in a card file system until 1979 when the database was first developed electronically. The database now records information on all Australian stratigraphic units and their usage in published literature. <p>The database contains about 17500 currently approved stratigraphic names and over 36000 variations, most of which are superseded, obsolete, or misspelt versions of the current names. This information is based on over 16000 published references. <p>The database is maintained by Geoscience Australia on behalf of the Australian Stratigraphy Commission, a standing committee of the Geological Society of Australia. <p>Procedures can be queried at: http://www.ga.gov.au/data-pubs/datastandards/stratigraphic-units? <p>Data can be queried and downloaded at the ASUD website at: https://asud.ga.gov.au/ <p>Email contact: mailto:stratnames@ga.gov.au
