摘　　要：开放共享是地理信息应用的重要研究方向,是实现陆海空地理信息融合的有效方式之一,是地理信息进一步融入信息行业的重要趋势。电子海图作为一类重要的海洋地理信息,却一直处于行业封闭状态,在术语、数据标准与显示方法等方面未能很好地融入地理信息主流。针对电子海图的图示表达问题,剖析了IHO S-52和IHO S-100两个标准中的图示表达模型,提出了基于可扩展标记语言(extensive markup language,XML)的电子海图图示表达实现方法,通过对IHO S-57数据、S-52符号定义集合和S-52符号化指令的重构,构建了一种全开放式的电子海图可视化模式,为电子海图和其他地理信息图示表达机制的升级完善提供重要参考。Open sharing is one of the mainstream trends in the application of geographic information,and it is an effective way to achieve integration of land,sea and air information,as well as a feasible way to further integrate geographic information into the information industry.As a kind of important marine geographic information,electronic chart has been in a closed state of the industry.It has not been well integrated into the mainstream of geographic information in terms of concepts,data standards and display methods.In view of the portrayal of the electronic chart,the portrayal models of two standards(IHO S-52 and IHO S-100)were analyzed,and an XML based realization of portrayal model for electronic chart was proposed.By reconstructing the IHO S-57 data,the S-52 symbol definition set and the S-52 symbol instruction,a full opening display mode for electronic chart is constructed,which provides an important reference for upgrading the representation mechanisms of the electronic chart and other geographic information.
