Refraction Statics via GLI

Generalized Linear Inversion (GLI)

GLI is a model based ray-tracing method using well-known Hampson-Russell software.

The algorithm assumes that the near surface geology is described by layering that exhibits (i) smooth lateral variations in velocity, (ii) vertically homogeneity of velocity with an individual layer, and (iii) layer velocities increasing monotonically with depth.
