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 Mt Isa E Gravity Complete Bouguer Anomaly 1VD geodetic is a complete Bouguer anomaly grid for the Mt Isa Area E Gravity Survey (P200644). A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid. This gravity survey was acquired under the project No. 200644 for the geological survey of QLD. The grid has a cell size of 0.0075 degrees (approximately 802m). A total of 6123 gravity stations were acquired to produce this grid.
