This module is designed for efficiently picking the first-arrival traveltimes of seismic data. Geometry and trace information will be automatically and rapidly extracted from the SEG-Y header. User may pick shot sequentially, or use a shot map to guide the picking process. One of the unique features in this Time Picker is that it allows you to refine picks with reference to the predicted times resulted from tomographic inversion.
Initial picks are often inaccurate.
Thus, initial tomographic solution is often unreliable. Therefore, the approach integrates traveltime picking and tomographic imaging, and presents a reliable model-based method for picking arrival times.
