Airborne geophysics is indisputably a useful and cost effective approach to geophysical exploration and mapping in the appropriate situations. Depending on the objective, choosing conventional airborne geophysical surveys on projects of a certain size may result in substantial savings. In general, airborne surveys can be carried out over large areas in a matter of days, where the same ground survey might require weeks or months to achieve the same coverage. Certain projects lend themselves to airborne approaches. Objectives of groundwater exploration may necessitate covering an area up to hundreds of square kilometers, something more easily done from the air than...
