[[Basic seismic processing#Demultiple|Multiple interference]] can render amplitude with offset analysis of the CDP gathers meaningless. Generally, multiples are more dominant in data from the marine environment, but can also be strong in land data. Multiples are usually not visually evident in land data because of trace spacing and lower fold and will appear as strong random noise. But proper use of multiple removing programs, such as [[radon transform method]]s, can yield excellent results. | [[Basic seismic processing#Demultiple|Multiple interference]] can render amplitude with offset analysis of the CDP gathers meaningless.
