The present disclosure provides a method of processing and analysing gravity gradient data, the method comprises the step of providing the gravity gradient data for a survey area. The survey area has a ground surface that is profiled by features of the ground surface. The method also comprises the step of providing a model of the survey area including the profiled surface. Further, the method comprises the step of dividing at least a portion of the profiled surface of the survey area into a plurality of surface elements. Each surface element defines a cell that has a depth and is positioned over a region to which a largely uniform density is assigned. In addition, the method comprises calculating ground densities for at least some of the cells and calculating corresponding gravity gradient data such that the calculated gravity gradient data are comparable with the provided gravity gradient data obtained using the gravity gradiometer, whereby the calculated ground densities are indicative of a density distribution below the surface of the survey area. |
