EasyRefract — User manual

EasyRefract is the GeoStru software for processing seismic refraction surveys. It imports the seismograms of the spread, allows the picking of the first arrivals, builds the traveltime curves and derives the subsoil model with the G.R.M. (Generalized Reciprocal Method), returning the velocity and the morphology of the refractors.
