Research Xinming has done some work on the automatic generation of a seismic Wheeler volume by using a RGT volume obtained from seismic phase unwrapping. A seismic Wheeler volume is an important tool for seismic stratigraphic interpretation to portray the geologic time-space distribution of strata and the related depositional, non-depositional and erosional events. It is also valuable for seismic geomorphological interpretation by facilitating the extraction of isochronal stratal slices.
