摘要
电子海图显示与信息系统(Electronic chart display information system,ECDIS)开发库是各种海上信息系统的重要开发平台。满足国际标准的ECDIS开发库分成6大子功能系统,介绍每个子系统的具体作用。从最具特色的两个关键技术着手,说明了S57电子海图数据的解译方法和步骤,提出了S52数字表示的符号库实现技术和提高物标符号化速度的查找表数据结构。
Development library of electronic chart display and information system （ECDIS） is an important development platform for various marine information systems. A development library of ECDIS, which is compliant with international standards, is introduced. The functions of six subsystems of the library are given in detail. The method and steps to interpret the data of electronic chart $57 are described. Also, the method of realizing S52 symbolic library and the data structure improving the speed of symbolizing objects are presented.
