The influence of spread and shot systems is investigated using common measuring geometries like conventional crosshole and multi-offset VSP. Both synthetic and field data are used to understand better the importance of commonly used spread and shot systems in the image reconstruction process. In the synthetic case, a faulted structure under a near-surface low velocity layer is used. The results of the seismic images compared with the original model and the similarities in the structure and in the velocities are investigated. Tomograms derived from the real data are compared with ground truth. Our study shows that realistic spread systems can produce nearly the same quality images as in the ideal ones.
