[email protected] Summary Effects originating from a complex near surface model can severely degrade the quality of seismic data. Conventionally these effects are handled by assumptions on the model such as assuming vertical raypaths through the near surface. In this paper the effects are handled as a true imaging problem. Kinematic operators which will be used for redatuming are derived from the data. Through an adjusted tomographic inversion additional knowledge on the datum and near surface
