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.
This EL2881 Env9902, Acuitias SA Semi-Detailed Gravity Survey,2002A14 (P200264) contains a total of 1859 point data values acquired at a spacing between 400 and 1600 metres. The data is located in SA and were acquired in 2002, under project No. 200264 for None.

Statement: This EL2881 Env9902, Acuitias SA Semi-Detailed Gravity Survey,2002A14 (P200264), gravity point data contains ground gravity point data for the EL2881 Env9902, Acuitias SA Semi-Detailed Gravity Survey,2002A14 (P200264) survey acquired for None. This dataset contains a total of 1859 point data values. The data is located in SA and were acquired in 2002. The point located data were collected in grid layout at a station spacing between 400 and 1600 metres.
Terrain corrections were calculated using the INTREPID Geophysics software package. The processed data are checked by GA geophysicists using standard methods for assessing quality to ensure that the final data are fit-for-purpose.
All data are provided in EPSG:4283 coordinates, Australian Height Datum (AHD) and gravity datum of AAGD07. The units are degrees, meters, and micrometres per second squared, respectively.
