Introduction to Geophysics-KFUPM CMP Method Sample Same Subsurface Point – Common Depth Point 4 TimesThe common depth point (CDP) is the halfway point of the path only where the Earth is horizontally layered; it is situated vertically below the common midpoint (CMP). A gather is a family of traces (e.g. shot-point … Jumpstart your career! Learn from a vast source of knowledge, that you know you need, but couldn’t find anywhere. Dive deep into lighting, CG techniques, materials, color, design and archviz business. And look at it all from a wider perspective. Whether you want to understand a subject in depth or need a good portion of inspiration. The sum of the traces of seismic reflection data, acquired from a roll-along survey, which correspond to the same common depth point but which originate from different seismic profiles and different offsets.

Audio bit depth. An analog signal (in red) encoded to 4-bit PCM digital samples (in blue); the bit depth is four, so each sample's amplitude is one of 16 possible values. In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample.
