Improving Technology on Identification Depth Datum About Temporary Tide Station

With the continuous improvement of the mapping equipment and data processing, the accuracy of temporary tide station datum has become the main factors of tidal correction accuracy and the precision of the final mapping. In this paper, added time consistency requirements to improve the credibility on the temporary tide station datum delivery estimates, and making sync correction for the tidal datum calculating with tidal range tatio method,effectively improved the transmission accuracy of the tidal datum. Finally, the paper gived a feasible way to assess its accuracy.
