1. A process for generating a bin of common mid-point traces from a three dimensional seismic survey data set, each of the traces having a shot location and a receiver location associated therewith, the process comprising:

  • gathering from the data a plurality of traces having a common reference point, whereby a common reference point bin is defined and whereby each of the plurality of traces has an offset associated therewith;

    assigning a coordinate set to a plurality of traces in the common reference point bin, wherein the coordinates are associated with the shot position and the receiver position associated with the traces and wherein, from the coordinates, the offset and direction of a line between the shot and receiver is determinable, whereby a coordinate-designated set of traces is defined; and

    organizing the coordinate-designated set of traces into a set of bins having a regularized number of traces.
