Reprocessing aeromagnetic data using modern semi-automatic interpretation methods

Abstract Modern airborne geophysical data acquisition systems (such as aircraft, helicopters, and drones) can aquire large amounts of data quickly. Semi-automatic intepretation methods that provide initial estimates of source location and depth have been in widespread use since the 1970s. The output of these methods is used as the starting point for a detailed interpretation, based on forward modelling and inversion. One of the earliest methods in widespread use on computers was Euler deconvolution (Thomson, 1982; Reid et al., 1990)
