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 AFGN Absolute Gravity Survey 2010 (P201099) contains a total of 11 point data values acquired at a spacing of 850 metres. The data is located in ACT, NSW, NT, QLD, SA, TAS, VIC, WA and were acquired in 2012, under project No. 201099 for Geoscience Australia.

Statement: This AFGN Absolute Gravity Survey 2010 (P201099), gravity point data contains ground gravity point data for the AFGN Absolute Gravity Survey 2010 (P201099) survey acquired for Geoscience Australia. This dataset contains a total of 11 point data values. The data is located in ACT, NSW, NT, QLD, SA, TAS, VIC, WA and were acquired in 2012. The point located data were collected in points layout at an average station spacing of 850 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.
