The emphasis has been on projects where structure is of fundamental importance and conventional techniques have proved inadequate. Two products derived from the FG-filtered data are now standard. A FG-filter may be applied to any filtered product of potential field data. For example, total field data includes polarisation effects, whereas the analytic signal is free from those polarity effects. Structural analyses may be undertaken using the FG-filtered analytic signal.
Current research is focused on the analysis of the structural lineament maps.
These lineament maps have a large amount of information which would benefit from quantitative and statistical analyses. We are designing a digital processing option that would lend itself to import into lineament and structural analysis software. Textural aspects of the filter output has not been used to its full potential. This is currently under investigation. This work is being undertaken in collaboration with structural geologists and image processing experts.
