基于实时发布WEBGIS技术的港口助航信息系统

港口及其持续稳定的发展是沿海地区经济繁荣的基础保证。近年来，沿海城市发展快速，港口交通变动越来越拥挤，因此，港口交通安全是保障港口城市发展的重要内容之一。通过深入研究助航信息数据内容以及数据共享发布组织模式，运用WEBGIS（网络地理信息系统）技术，构建了以符合国际IHO-S57标准电子海图规范为基础数据、叠新信息、保障航行安全提供了可能。针对实施过程的技术拓展，对系统作了简要的介绍。

Port Navigation-Supporting Information System Based on Real-time WEBGIS Distribution Technique

Port and its sostenuto stable development is the fundamental ensure of economic boom of littoral.Nowadays,the 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 paper,using the technique of WEBGIS,constructed the Real-time WEBGIS Port Navigation Supporting information 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 paper gives a simple introduction.1
