基于IHO S-125标准的海上导助航服务数据

    Chart data of marine Aids to Navigation based on IHO S-125 standards

    • 摘要: S-125标准是基于IHO S-100标准建立的关于海上导助航服务的产品规范,未来航标动态信息的发布将遵守这一规范。为促进我国官方S-125产品的生产,从数据结构、数据编码、要素目录和编码、图式表达等方面分析了S-125的数据模型,通过制作S-125航标动态信息的测试数据,测试了S-125产品在ECDIS上的显示与应用。根据测试结果,总结了当前S-125版本存在的一些问题,并提出了相关的建议。该研究成果可为我国官方开展S-125产品生产提供参考。

       

      Abstract: The S-125 standard is based on the IHO S-100 standard and serves as the product specification for maritime navigational aid services. In the future,the release of dynamic information regarding navigational marks must adhere to this standard. To facilitate the official production of S-125 products in China,an analysis of the S-125 data model was conducted,encompassing data structure,data encoding,feature catalog and coding,chart symbology,and other aspects. By generating test data for S-125 navigational mark dynamic information,the display and application of S-125 products on ECDIS were evaluated. Based on the test results,some issues with the current version of S-125 were identified,and relevant recommendations were proposed. The research findings can serve as a reference for China’s official implementation of S-125 product production.
