The Surface Hydrology Points (Regional) dataset provides a set of related features classes to be used as the basis of the production of consistent hydrological information. This dataset contains a geometric representation of major hydrographic point elements - both natural and artificial. This dataset is the best available data supplied by Jurisdictions and aggregated by Geoscience Australia it is intended for defining hydrological features.

These data represent the OZCHRON database of physical age determinations of Australian rocks, and the radiogenic isotope ratios used in determining the ages. OZCHRON datasets comprise bibliographic references, analytical data and pooled results for samples derived using the Rb-Sr, SHRIMP, U-Pb, and Sm-Nd age determination methods.

The Landsat series of satellites commenced acquiring remotely sensed data with the launch of Landsat 1 in 1972. The Landsat satellites travel at an altitude of 705 kilometres and provide coverage of the entire globe every 16 days. Landsat 5, launched in 1984, carries the Thematic Mapper (TM) sensor in addition to the Multispectral Scanner (MSS). The Thematic Mapper is a higher resolution sensor. It provides imagery in seven spectral bands (called Bands 1-7), covering the visible and near, middle and thermal infrared parts of the electromagnetic spectrum. TM has a 30-metre pixel resolution for all bands except Band 6 which has a 120-metre resolution. Its ground swath is 185 kilometres. A full scene is 185 kilometres by 172 kilometres. The archive of ACRES products includes TM data from September 1987 to December 1999 and July 2003 onwards.

Geoscience Australia (GA) has created a unique collection of 3D structural and geological models and model inputs for Australia and its near shore regions. Currently the collection contains a variety of 3D volumetric models and surfaces that were produced for specific projects at regional to continental scale. The approximately 40 regional scale models in the collection cover roughly 1/3 of the Australian continent. The models capture 3D stratigraphy and architecture, including the depth to bedrock and the locations of different major rock units, faults and geological structures. The geologic models represent the integration of geophysical surveys, seismic surveys, borehole data, field geology, and geochemical data, the majority of which will now be available through this and other RDSI collections. In their current form, the 3D models provide a valuable input to simulations of geological processes. However, the plan over time is to use the HPC capability at NCI and the large storage volumes available to dynamically integrate the various models and geological, geochemical and geophysical derivative products to then create a unified 3D model for the entire continent. Separately and then cumulatively, these models will provide an important new basis for describing and understanding Australia's geologic evolution and resource wealth. Currently there are no international open standards for the development and storage of 3D geological models, which is why they are difficult to integrate or stitch into nationally integrated data sets. The lack of consistency of the models means that each has to be transformed into formats compatible with existing HP modelling and simulation software. It is hoped that through exposing these 3D geological models into a HP collaborative environment that this will foster and accelerate the development of international standards and tools necessary for the assimilation of 3D geological models into a variety of HP programs. <b> Note: This record has been superseded by eCat 144629:</b> - <a href="https://pid.geoscience.gov.au/dataset/ga/144629">https://pid.geoscience.gov.au/dataset/ga/144629</a>

The Gazetteer of Australia is the authoritative data source providing information on the location and spelling of approved place names on the Australian mainland extending to the 3 mile marine limit, together with its external territories, except the Australian Antarctic Territory. Contains all the authorised place names covering Australia's land and offshore areas. The 2010 release consists of over 300,000 place names. The Gazetteer is compiled by the Geospatial and Earth Monitoring Division of Geoscience Australia, on behalf of the Committee for Geographical Names in Australasia (a committee of the Intergovernmental Committee on Surveying and Mapping (ICSM)). Data is sourced from the relevant State and Territory jurisdictions (ACT, NSW, NT, QLD, SA, TAS, VIC, WA) along with various Australian Government agencies (Australian Antarctic Division, Australia Hydrographic Service, and Geoscience Australia).

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).

The geomorphic features of the seafloor in the Australian Marine Jurisdiction were identified using the Australian Bathymetry and Topography dataset (Webster & Petkovic 2005). Twenty one feature types were identified and mapped for an area including the seafloor surrounding the Australian mainland and island territories of Christmas, Cocos (Keeling), Macquarie, and Norfolk Islands (Heap & Harris 2008). Some examples of these geomorphic features include: abyssal plains, trenches, canyons, and seamounts.

National Exposure Information Systems (NEXIS) provides nationally consistent exposure information about Australia's residents and buildings for use in assessing the risk from natural and man-made disasters, in order to inform policy and operational decision makers of the impact on Australian communities. NEXIS can provide detailed residential, commercial and industrial information for every Local Government Area in Australia.
