Automatic timing of a seismic event along a section or throughout a volume based on specifying a seed point to indicate the event to be picked. Often based on a crosscorrelation over a specified narrow window. The autopicker generally stops if the crosscorrelation maximum is less than a set threshold, and a new seed point must be indicated to continue the picking. The pick is usually the amplitude and time for a maximum or minimum, which is sometimes selected from a quadratic fit to 3 or more points to interpolate between sample values.
