Figure 2. Map views of thin stratigraphy (a) and (b), used to depth register P-P and P-SV images. In map view, equivalence of thin P-P and P-SV channel features results in P-SV time 1,964 ms (b) being defined to be depth equivalent to P-P time 796 ms (a). It is more difficult to determine depth-equivalent image coordinates using 2-D section views (c) and (d) of this same stratigraphy. Horizontal yellow lines across the section views define the positions of the time slices. The vertical sections are positioned along inline coordinate 2100. Channel features A through F on the map views are the same features labeled A through F on the vertical sections.
