摘　　要：针对电子航海图现行符号库标准S-52难以利用和扩展的问题,分析研究了S-52标准中基本线型和复杂线型的结构表达方法,提出了两种新方案:一是基于SVG的电子航海图线型结构表达方法,二是基于SVG与XML参数的电子航海图线型结构表达方法。最后,按照第二种方案,实现了S-52线型结构的重构和转换,构建了完整的电子航海图线型符号集合。In this paper,the problem of the difficulty and utilization of the current symbol library standard S-52 in the electronic navigation chart is analyzed.The structure expression methods of the basic linestyle and the complex linestyle in the S-52 standard are analyzed.Two new schemes are proposed:one is based on SVG.,and the second is based on the SVG and XML parameters.Finally,according to the second scheme,the reconstruction and transformation of S-52 linestyle structures are realized,and a complete electronic nautical chart linestyle set is constructed.
