| 摘 要： | 建立统一、规范的深度基准体系是海洋测绘成果应用的基本保证。为了消除目前海图应用中水深注记基准面不一致的影响,本文在以往研究成果的基础上,提出了以平均海面基准为中介的海图新旧深度基准的转换体系,并以某实验海区水深数据为例,构建了基于深度基准面更新模型的海图水深注记的更新方法。经试验验证效果良好。

| Abstract: | Building the united and normative sounding datum is the basic guarantee of hydrographic surveying and mapping.In order to remove the conflicting chart datum of chart soundings,a transforming scheme based on the mean sea level datum was put forward about converting the old chart datum into new system in the paper.A chart depth data updating method was established based on the newly introduced chart datum with the experimental sounding data.The result was proved perfect. |
