摘　　要：针对内河航行规则、航道通告、航道尺度及锚地、停泊区、横驶区等重要区域位置描述等助航信息非结构化、阅读不直观等问题,提出了一种全开放式的内河航道助航信息可视化模式。以长江航道为例,结合长江电子航道图,开展内河航道助航信息可视化模型的应用研究。通过参考电子航道图制作的相关标准规范,对比各类航道信息矢量化方法技术特点、应用场景及实施效果,总结归纳了标准符号库、地理围栏和虚拟航标三种模型的优缺点,解决了不同类型助航信息的图示表达问题。研究证明,该模式灵活、开放,适用于多种业务场景,可为助航信息及其他航道信息图示表达机制的升级完善提供参考。It was a task in visualization of important navigation information in waterway such as navigation rules,notices,dimensions and descriptions of important areas such as anchorages,berthing areas,and lateral areas.This information was displayed in an unstructured form,and it was intuitive to read.A fully open visualization mode of navigation information for inland waterway was proposed in this paper.Taking the Yangtze River waterway as an example,combined with the electronic waterway map of the Yangtze River,the application research of the visualization model of inland waterway navigation information was carried out.Relevant standards and specifications made by referring to electronic waterway map,the technical characteristics,application scenarios and implementation effects of various waterway information vectorization methods were compared.The advantages and disadvantages of the three models of standard symbol library,geofence and virtual navigation aid were summarized,and the graphical expression of different types of navigation information was solved.Research proves that this model is flexible,open,and suitable for a variety of scenarios,and can provide an important reference for the upgrading and improvement of the graphic representation mechanism of navigation supporting information and other waterway information.
