Gravity data measure 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. This Goldfields Gravity Survey P201362 Spherical Cap Bouger Anomaly 267GU First Vertical Derivative Geodetic.ers is the first vertical derivative of the spheical cap Bouguer anomaly grid for the Goldfields Gravity Survey 2013 (P201362). This gravity survey was acquired under the project No. 201362 for the geological survey of WA. The grid has a cell size of 0.00482 degrees (approximately 499m). A total of 8119 gravity stations at 2500m spacing were acquired to produce this grid. A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
