The traditional process of the iteration of preliminary and final discrete tidal zoning, as well asrnthe need to post-process tide station data for the computation of tidal datums and tide reducers, has been a delaying factor in the production of nautical charts.rnHowever, with the introduction of TCARI, the post processing steps are all but eliminated and the TCARI application is made by the on-board ship processing system before the data are sent to a marine center for chart compilation. This enhancement also eliminates one of the known error sources and limitations in tide reducer compilation, that of the discrete tidal zoning.
