摘要
标志描绘是 GIS 的重要功能。在不同 GIS 平台分享符号的信息为 GIS 应用程序和用户是必要的。这篇论文讨论必要性，可能性和在不同 GIS 平台分享一个标志图书馆的答案技术。线路地图如下被设计：首先，为标志图书馆当模特儿建立一个一般数据，然后格式化设计标准交换，并且最后格式化号召 GIS 制造商为标准交换为他们的标志图书馆提供交换工具。这篇论文分析 GIS 符号的图书馆的一般特征，给一个标志图书馆模型和 XML 的一篇草稿标志图书馆交换格式的纲要。
Symbol portrayal is an important function of GIS. Sharing symbolic information in different GIS platforms is necessary for GIS applications and users. This paper discusses the necessity, possibility and solution technique of sharing a symbol library in different GIS platforms. The route map is designed as follows： first, to set up a general data model for the symbol library, then to design a standard exchange format, and finally to call on the GIS manufacturer to provide the interchange tools for their symbol library for the standard exchange format. This paper analyzes the general characteristics of GIS symbolic library, gives a symbol library model and a draft of XML schema of the symbol library exchange format.
