港口助航信息实时发布技术的应用研究

Research on WebGIS Real_time Distribution System of Port Navigation_supporting Information

基于港口助航信息实时发布的应用需求,此文研究了助航信息数据内容和数据共享发布组织模式,运用WebGIS(网络地理信息系统)技术,构建了符合国际IHO-S57规范的标准电子海图基础数据、叠加实时的各种助航信息以及运行于互联网上的港口助航信息实时共享发布系统。该系统已在厦门港航标动态信息共享发布中得到应用,能使得进出港船舶、涉海单位和公众在最短时间内获取发布的港口助航信息。

Port and its sostenuto stable development is the fundamental ensure of economic boom of littoral. Nowadays, constructing scope of littoral cities is getting scale-up, and port traffic is getting crowded, so ensuring the safety of maritime traffic is one of the premises of port developing.Through deep research on navigation-supporting data content and data-sharing distribution mode, this thesis, using the technique of WebGIS, constructed the Port Navigation-supporting Information WebGIS Real-time Distribution System, and this system is based on the map data standard of IHO-S57, and can be overlaid many kinds of real-time navigation-supporting information, and it works on the web. This system makes it possible for the in-and-out port ships to get the latest navigation-supporting information, and ensure ship＇ s navigation safety further. From the technique of realization, this thesis gives a simple introduction.
