| Abstract: | In this paper, based on the definition and arithmetic for the level of lowest astronomical tide, depended on perennial height of tide observations data collected from 14 long-term tide stations in China coastland, the applicability for lowest astronomical tide in China coastland is analyzed and evaluated. The research result shows that the accuracy of lowest astronomical tide in China coastland can achieve the centimeter level, in which is applicable for establishment of high precision chart datum in China. |
