Thomson Gravity Complete Bouguer Gravity geodetic

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 Thomson Gravity Complete Bouguer Gravity geodetic is a complete Bouguer anomaly grid for the Thomson NSW Gravity Survey, 2007 (P200721). This gravity survey was acquired under the project No. 200721 for the geological survey of NSW. The grid has a cell size of 0.0037 degrees (approximately 384m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 4728 gravity stations were acquired to produce this grid.
