This service provides header and observation data for gravity stations located throughout continental Australia and Remote Offshore Territories. Data sources include the Australian National Gravity Database (ANGD) and the Australian Fundamental Gravity Network (AFGN) maintained by Geoscience Australia (GA). Data has been obtained by Surveyors, Commonwealth and state/territory Governments, private companies, and educational institutions. Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

The Australian National Gravity Database (ANGD) is underpinned by the Australian Fundamental Gravity Network (AFGN) which provides the datum for gravity surveys conducted throughout Australia. Geoscience Australia maintains the AFGN, with assistance in the form of updates from State and Territory Geological Surveys and Surveyors. Geoscience Australia maintains the ANGD, which contains data from field mapping surveys conducted by Geoscience Australia and other agencies throughout Australia and its Remote Offshore Territories. Data have been sourced from within Geoscience Australia, State and Territory governments and agencies, mineral and petroleum exploration companies, universities and overseas organizations. Gravity data has been acquired since 1950 until the present day.
