“…Future work will include a comparison of the residual Bouguer anomaly map resulting from the graphical method described above with those obtained with other geophysical methods for the separation of the regional and residual fields. These methods include: the estimation of the regional field by a polynomial fit (Nettleton, 1954); frequency-domain filters built to separate long-wavelength anomalies from the gravity field (Petersen, 1979); upward continuation transformation that tends to accentuate long-wavelength anomalies that are generally caused by deep sources (Jacobsen, 1987); and space-domain filters that replace 'short-wavelength' anomalies by interpolated values (Naudi and Dreyer, 1968). These methods will be discussed qualitatively using the three criteria listed above and their usefulness for gravity modelling will be evaluated.…”

“…This applies particularly to depth estimation from the log energy spectrum. Wavenumber analysis, as pointed out by Pedersen (1979), has the advantage of being quick but rather coarse, and errors can be quite high.…”

“…Important contributions include the 'matched' filtering approach of Spector and Grant (1970), wavenumber filtering and equivalent layer analysis by Pedersen (1979;1991) and differential upward continuation based separation filtering by Jacobsen (1987).…”

“…Linear inversion methods are commonly adopted to solve these more complex problems involving many unknowns and residual anomaly observations (e.g. Bott 1973;Emilia 1973;Mayhew 1979;Peterson 1979;yon Frese et al 1981a).…”
