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 Webb Gravity Survey (P200660), Bouguer 1VD grid is a first vertical derivative of the Bouguer anomaly grid for the Webb Gravity Survey (P200660) survey. This gravity survey was acquired under the project No. 200660 for the geological survey of WA. The grid has a cell size of 0.0047 degrees (approximately 502m). A total of 4092 gravity stations were acquired to produce the original grid. A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.
