We can enhance our recognition of stratigraphic features by using [[seismic data]] [[attributes]], reflection strength, coherence, and instantaneous phase. These attributes are well suited to stratigraphic interpretation and are an effective interpretive tool when displayed in map view.

Three-dimensional coherence is a measure of the similarity of neighboring seismic traces in 3-D data. It is useful for mapping paleogeomorphology and faults.<ref name=ch21r4>Bahorich, M., S., Farmer, S., L., 1995, 3-D seismic discontinuity for faults and stratigraphic features: the coherence cube: The Leading Edge, vol. 14, no. 10, p. 1053–58., 10., 1190/1., 1437077</ref>
