Figure 1. Surface (S) and Ping (P) in a Scene
A Surface-ping intersection, SP, is that part of a surface S which intersects with a ping, P. The diagrams below show a surface and multibeam ping (in a scene), the original ping (in a multibeam echogram), and the resulting surface-ping intersection (in full view and zoomed without for clarity). The surface-ping intersection is visible on a multibeam echogram as a yellow line.
