A method of seismic shot-record migration includes the steps of generating seismic or acoustic waves into an earth formation from one or more sources with the sources being spaced some finite distance from each other. Next, one or more spaced receivers receive a seismic signal after the signal reflects or diffracts off of a subterranean feature. Next, a source location and a receiver location is arbitrarily selected. Finally, input data is mapped or migrated according to one of two equations, or both equations, to produce output data. The output data is then suitable for further processing by other seismic analysis techniques.
