GPS positioning enables flying with closer line spacing than previously, and this has stimulated a demand for lower survey altitudes with flight heights of the order of 60-80 m now common. Radiometric recording of 256 channels of gamma-ray data is now virtually standard and in-flight stabilisation of these systems has improved markedly. Digital acquisition systems are now designed to facilitate both in-flight and post-flight verification of the data.
