国际标准电子海图显示平台的研制

随着我国数字海图产品不断的生产完善，研制自主知识产权的“电子海图显示与信息系统（ECDIS）”逐渐成为工作的重心，而这项任务的核心是符合S-57数据传输标准及S-52电子海图模式的显示平台的研制，以此为基础才能研制出我国自主知识产权的ECDIS。在研究电子海图国际标准化的基础上，通过大量的技术实践，实现了自主知识产权的国际标准电子海图显示平台，为我国建立自主知识产权的ECDIS打下了坚实的基础。

Research on the International Standard Electronic Chart Display and Information System

Electronic chart is a new navigation aid that can provide significant benefits to maritime navigation,safety,and commerce.Electronic chart is a real-time navigation system that integrates a variety of information that is displayed and interpreted by the mariner.IHO Special Publication 52(IHO-S-52) is the IHO Specification for Chart Content and Display of ECDIS.This paper discussed the key problems,which will provide the theoretical foundation and practical experience.On the bases of analyzing the S-52 standard,this paper discussed the key technology in the Electronic chart display system,including such follows:propose a new automatic assignment symbols which consist of points,lines and areas.According to the S-57 standard and S-52 standard,it is decided by the objects attribute when a symbol was shown.
