Surface wave data are processed to retrieve dispersion curves that are inverted to estimate velocity models of the subsurface. Recent approaches avoids the inversion step using data transforms that estimate directly the velocity. Dispersion curves are discontinuous and noisy data that requires interpolation and smoothing.
