摘要
Abstract
Water level control is the main technique in data processing of the bathymetry.The precision of water level correction is originally impacted by the quality of the tidal observation data.Aiming to solve problems of data missing phenomenon and weave disturbing in the tidal observation data with pressure tide gauge,the correlative theoretic research has been discussed and the physical tidal data processing module has been designed and developed,which can meet the need of the precision seawater density correction model and the depth datum transform model.The results show that the tidal data precision can be obviously improved after several processing steps,the method and the physical tidal data processing module can be widely applied in the water level control of the bathymetry and other marine engineering.关键词
