Gridded Bouguer gravity anomalies onshore and free-air anomalies offshore with satellite measurements filling the gaps in coverage. Grid mesh is 0.5 minute (approximately 800 metres). This second edition replaces the 1.5 minute gridded dataset released in 1997.

This gravity anomaly image has been generated from the Bouguer Gravity Anomaly Grid of Australia 2016. The Bouguer grid has been image enhanced and displayed as a hue-saturation-intensity (HSI) image with sun shading from the northeast. The product has been derived from observations stored in the Australian National Gravity Database (ANGD) as at February 2016 together with the 2013 New South Wales Riverina gravity survey. Out of the almost 1.8 million records in the ANGD approximately 1.4 million stations were used to generate this image. The image shows spherical cap Bouguer anomalies over onshore continental Australia. The data used in this image has been acquired by the Commonwealth, State and Territory Governments, the mining and exploration industry, universities and research organisations from the 1940's to the present day. The spherical cap Bouguer anomalies in this image are the combination of Bullard A and B corrections to the Free Air anomaly values using a density of 2670 kg/m^3.

Survey conducted on east-west lines. The release consists of Grid, Image and Point Data over approximately 8x10km area located on the Kalgoorlie 1:250 000 sheet.

GADDS runs the JetStream software package created by Intrepid Geophysics Pty Ltd. GADDS was implemented for web-data delivery of Geoscience Australia's land gravity and airborne survey datasets in both grid and (point/line) vector data formats. GADDS works on geodetic magnetic and gravity grids of continental Australia as well as individual survey magnetic, radiometric and elevation datasets. Gravity point data from Australia is extracted from an Oracle database. The GADDS front-end application was developed in-house at Geoscience Australia by Aaron Sedgmen.

Geoscience Australia and the Office of Minerals and Energy Resources SA announce the release of digital point located and gridded gravity data from recent gravity surveys over the South Olympic, Lake Harris and Mulgathing regions of the Gawler Craton in South Australia. The data were acquired by Primary Industries and Resources South Australia (PIRSA) as part of its Targeted Exploration initiative South Australia (TEiSA) in collaboration with Geoscience Australia's Gawler Craton Mineral Promotion Project. Data collected during the survey provide the framework necessary for government and industry to assess resource potential, determine land use and environmental management policies, and aid in the planning of more detailed exploration activities. The survey comprises 3533 new gravity stations acquired over various station spacings. For the South Olympic region, stations were acquired on irregular 4 x 4 and 2 x 2 km grids. A regular 4 x 2 km grid was used in the Mulgathing region. In the Lake Harris region, data were acquired on a 4 x 1 km grid with a portion being infilled at 2 x 1 km, over the outcropping Lake Harris greenstone belt. Data were acquired over the period April to May 2001. The digital data are available from Geoscience Australia on CD-ROM. Contact the Sales Centre.
