  • 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.

  • Scanned 250k geological maps of Australia in geotiff format. Data is cropped to map graticule, rectified to geographic coordinate system, GDA94, GRS80 ellipsoid. Data is uncompressed, not tiled, 8bit colour, 250dpi and 25m pixel size. The map editions are current only to 2002.

  • The Australian Tsunami Database (ATDB) was commissioned by the Australian Geological Survey Organisation as part of a national database of natural hazards in Australia. Its scope, however, is broader with data for the Southwest Pacific, Southeast Asia and Australia. The ATDB aims to furher understanding of the tsunami hazard in these regions by presenting the data from myriad source in a single comprehensive resource that is both accessible and useful. The ATDB is constructed in Borland Paradox for Windows, a relational database that facilitates easy data entry and data extraction. The ATDB contains information regarding tsunami dates, time, locations, effects and comments, and is designed so that it can be linked to the earthquake database run by teh Australian Seismological Centre.

  • Geoscience Australia is responsible for the definition of Australia's maritime boundaries. To assist in this task National Mapping has developed the Australian Maritime Boundaries Information System (AMBIS). AMBIS 2001 is a data product, derived from AMBIS, providing access to the data for Australia's Territorial Sea Baseline (TSB) and maritime zones. AMBIS 2001 data comprises the TSB and the outer limits of each zone, together with quality attributes. Base points that generate the zone boundaries are supplied in separate files and an extensive user guide provides useful background information. All data coordinates are supplied in the Geocentric Datum of Australia (GDA 94) which is effectively identical to the WGS84 datum. National Mapping is committed to the maintenance of the AMBIS data to ensure it reflects the changing nature of Australia's coastline and hence the various maritime zone limits. To this effect, a newly revised AMBIS 2001 product (version 1.1) has been released in October 2001. This new version incorporates additional treaty information, additional data in the vicinity of Swains Reef in Queensland, an improved representation of the TSB, several other minor corrections, a wider range of formats and simplified attribute tables.

  • Please note: This product has been superseded by 50m Multibeam Dataset of Australia 2018. - This tile contains all multibeam data held by Geoscience Australia on August 2012 within the specified area. The data has been gridded to 50m resolution. Some deeper data has also been interpolated within the mapped area. The image provided can be viewed on the free software CARIS Easyview, available from the CARIS website: www.caris.com under Free Downloads.

  • This is an extract from the OZTemp database, an updated and improved version of the AUSTHERM05 borehole temperature database previously described by Chopra and Holgate (2005). OZTemp currently contains 5513 individual wells and 17 247 temperature and/or temperature gradient data records.

  • 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.

  • 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.
