水下地形测绘中潮位改正误差分析

Tide Correction Error Analysis of Submarine Surveying and Mapping

从宁波市1∶2.5万水下地形图测绘生产项目出发,分析了项目中水深值的潮位改正以及验证外推潮位改正可行性的方法。主要介绍了根据施测海域的潮汐性质合理布设验潮站,利用多个三角分带对同一区域进行潮位改正并对改正结果进行了比对、统计与分析。

This paper based on the 1∶ 25000 scale submarine surveying and mapping project,analyses the feasibility of extrapolation tide correction method. This paper introduced how to set temporary tide station according to the nature of the tide,statistically analysis the depth of the same position corrected by different triangle.
