A wavelet method is applied to the analysis of gravity potential. One scaling function is proposed to generate
wavelet. The scaling function is shown to be replaced to the Green’s function in gravity potential. The upward
continuation can be expressed as a wavelet transform i.e. convolution with the scaling function. The scaling factor
indicates the height variation. The multiscale edge detection is carried by connecting the local maxima of the wavelet
transform at scales. The multiscale edge represents discontinuity of the geological structure. The multiscale edge method is
applied to gravity data from Masan and Changwon.
