New geophysical datasets for Ashburton, Officer Basin and Mount Isa regions

Datasets from four new geophysical surveys, released since February 2007, will be a valuable tool in assessing the mineral potential of the respective survey areas.

The new data includes three airborne magnetic and radiometric surveys including the Ashburton region and Officer Basin in Western Australia and the Mount Isa region in Queensland as well as a gravity survey in the Mount Isa region.

The data for all surveys were acquired in surveys conducted in 2006 which were managed by Geoscience Australia on behalf of the Geological Surveys of Queensland and Western Australia.

The data have been incorporated into the national geophysical databases. The point-located and gridded data for the four surveys can be obtained free online using the GADDS download facility.

New Gazetteer of Australia released

New Gazetteer of Australia.

The Gazetteer of Australia 2006 is the authoritative source of Australian place names and their location, whether they are natural features such as mountains and rivers or built features such as homesteads and bridges.

The Gazetteer is revised annually by Geoscience Australia under the auspices of the Intergovernmental Committee for Surveying and Mapping (ICSM) with data provided by state, territory and Commonwealth Government authorities responsible for administering place names. The 2006 version includes more than 320 000 official and unofficial place names and their co-ordinates in GDA 94 (Geocentric Datum of Australia 1994) covering Australia and its offshore regions.

The latest version includes the addition of new place names, the removal of invalid records and the revision of place names preserved for use in community geographic domain names (for internet sites). To check the spelling of a town's name or a geographical feature visit Geoscience Australia's Place Name Search facility.

The Gazetteer of Australia 2006 can be used for a variety of purposes including: locating a place on a map, searching by place names or relating services to locations online, showing place names in digital mapping applications (for example, the place name search facility in NATMAP Raster Digital Maps), and adding value to a map.

The Gazetteer of Australia 2006 is available on CD ROM from Geoscience Australia's Sales Centre.
