Optimising FTG Gravity Data with Axis Realignment

Full tensor gravity gradiometry (FTG) measures the complete gravity field; because of this we are able to realign the axes of the tensor to better image geology. Consequently we are able to design surveys based on optimal acquisition and safety parameters, then realign during the interpretation stage to focus on geological strike direction. This is also a powerful technique for interpreting surveys with more than one dominant strike trend. The realignment technique is demonstrated using a dataset from Mauritania, acquired in 2010.
