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.

This documentation contains information that is current at the time of the release of the Geofabric V2.1 products. Documentation is available at http://www.bom.gov.au/water/geofabric/documentation.shtml.

Compilation of data for the MINLOC database began in 1989 and now contains location data for mineral occurrences in Australia. Location data includes co-ordinates, name of occurrence, and commodity(ies). All data points are referenced. This dataset is a snapshot at the "Ending Date" of the current database entries.

Australian National Seismograph Network (ANSN) These data are the time series seismograph, hydroacoustic and infrasound data recorded from ANSN Australian National Seismograph Network (ANSN) These data are the time series seismograph, hydroacoustic and infrasound data recorded from 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.

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.

Please note: The data can be downloaded for free in parts. Wind multipliers are factors that transform regional wind speeds to local wind speeds considering local effects of direction, terrain, shielding and topographic influences. In order to assess the local wind hazard (spatial significance in the order 10's of metres), wind multipliers need to be computed, so that the regional wind speeds (order 10 to 100's of kilometres) can be factored to provide local wind speeds. This data package includes terrain, shielding and topographic multipliers for national coverage. It is based on tiles with dimension about 1 by 1 decimal degree in netCDF format. Each multiplier further contains 8 directions. The version 2 dataset was produced using the wind multiplier computation software 2.0. See Geocat 82481.

Calibrated time-series data are acquired from Geoscience Australia's geomagnetic observatory network in Australia and Antarctica. Indices of geomagnetic activity are derived from these time series. These primary and derived data are provided to international data centres and agencies, space weather analysts, the resource exploration sector, and research institutions. They are used in navigation, magnetic-field modelling, resource exploration and exploitation, space weather monitoring and geoscience research.

The National Catchment Database is a linked set of spatial layers and associated attribute tables describing key elements of the surface water hydrology of the Australian continent at a map scale of about 1:250,000. It is built upon the representation of surface drainage patterns provided by the GEODATA national 9 second Digital Elevation Model (DEM) Version 3 (ANU Fenner School of Environment and Society and Geoscience Australia, 2008). The stream network and catchment boundaries contained within the database form foundation elements of the Bureau of Meteorology's Australian Hydrological Geospatial Fabric (Geofabric), the spatial framework that underpins the Australian Water Resources Information System (AWRIS) (http://www.bom.gov.au/water/geofabric/index.shtml). This database adds additional environmental attributes not available through the AHGF. The database contains Levels 1 (drainage divisions) and 2 (aggregated river basins group) National Catchment Boundaries (NCB) in raster format including NCB Pfafstetter coding. The Vector format is available from the Bureau's Geobraic website.

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).

This collection includes calibrated time-series data and other products from Geoscience Australia's geomagnetic observatory network in Australia and Antarctica. Data dates back to 1924. <b>Value: </b>These data are used in mathematical models of the geomagnetic field, in resource exploration and exploitation, to monitor space weather, and for scientific research. The resulting information can be used for compass-based navigation, magnetic direction finding, and to help protect communities by mitigating the potential hazards generated by magnetic storms. <b>Scope: </b>Continuous geomagnetic time series data, indices of magnetic activity and associated metadata, Data dates back to 1924.
