Research on WEBGIS real-time distribution system of port navigation-supporting information

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 instant 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.
