1. A seismic exploration method that comprises: obtaining seismic trace data from a common field file trace number or common channel across multiple receiver lines captured in response to multiple source events so that an arrangement of midpoints associated with the seismic trace data includes diagonally adjacent midpoints; interpolating between seismic traces corresponding to diagonally adjacent midpoints to obtain diagonally interpolated traces; and generating a final image based at least in part on the diagonally interpolated traces.
