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.

This map contains information on Oil and Gas pipeline infrastructure. Attributes have been added to comply with data standards and minor coding of line work has been achieved using annotation from the map. Further data has been added, specifically for the specific Acreage Release Areas.

Current understanding of Australia's geothermal resources is based on limited data such as temperature measurements taken in petroleum and mineral boreholes across the country. Heat flow studies are rarer, with existing publicly available compilations containing less than 150 heat flow data-points for Australia. Both temperature and heat flow data are unevenly distributed and, where no data exist, the available information has been interpolated over large areas to generate national-scale maps. Geoscience Australia has acquired the field and laboratory equipment required to measure heat flow. It began thermal logging of boreholes across Australia in late 2008 and has since collected 155 temperature logs. In late 2009, the thermal conductivity meter became operational, allowing the project to begin thermal conductivity measurements of samples collected from logged boreholes. To help clear some of the backlog of samples collected during 2008-09, the measurement of some of these samples has been contracted out. This record details the first set of new heat flow interpretations to be released by Geoscience Australia. The remaining temperature logs will be interpreted for heat flow and released, as thermal conductivity data for these holes become available.

The Dynamic Land Cover Dataset of Australia is the first nationally consistent and thematically comprehensive land cover reference for Australia. It is the result of a collaboration between Geoscience Australia and the Australian Bureau of Agriculture and Resource Economics and Sciences, and provides a base-line for identifying and reporting on change and trends in vegetation cover and extent. The thematic map product shows the land cover of Australia for the period of March 2000 to March 2008 in 34 Internation Standards Organisation (ISO) land cover classes.

These images are derived from the January 2002 edition of the "Magnetic Anomaly Grid of the Australian Region" (GEOCAT Record : 38820). That grid is the first integrated onshore/offshore magnetic anomaly grid for the complete Australian margin extending across 8S - 52S, 106E - 172E. The grid cell size is 0.01 degree (approx. 1 km). Earlier releases were restricted to portions of NW and SW Australia.

User-defined PDF maps of the Surface Geology of Australia (1:1 million scale) can be generated using the MapConnect online mapping application. The MapConnect tool allows users to zoom to an area of interest, overlay topographic information, and create PDF maps. The digital surface geology data may also be downloaded from the MapConnect application.

ArcGIS shapefile detailing GA's multibeam bathymetry holdings and coverage.

The product is a digital representation of the boundaries and names of Surface Water Management Areas defined by State and Territory water management agencies for use in national water resources reporting. Surface Water Management Areas generally correspond to Australia`s River Basin boundaries, however in some States and Territories the Areas are a sub-set or a major part of Australia`s River Basins. The dataset is produced by the National Land and Water Resources Audit (NLWRA) and distributed by Geoscience Australia. The data is suitable for GIS applications. Free online. Available in ArcInfo Export, ArcView Shapefile and MapInfo mid/mif.
