Analysis of the Problems About the Lowest Tidal Datum Meaning of the Chart Datum
摘要
Abstract
Because of the differences in time length of water level data and the algorithm,the lowest tidal datum meanings of the chart datum are different among long-term tide stations.The textual research on the algorithm of the chart datum in north seas shows that it is a general question.The solution is given in three levels:(1)for surveying units,the question can be judged by the differences among methods,and the result can be gained by principle that the spatial distribution of the chart datum is smooth.(2)for the departments of basic hydrographic surveying,the datum model should be developed for query and interpolation service.(3)for national management,the epoch and algorithm of the datum should be unified,and the long-term mechanism for datum adjustment should be set up.关键词
