摘要
随着数字制图技术的发展,电子地图的应用日益增多,为保证地理信息感知和认知的一致性与准确性,达到信息与资源共享,电子地形图符号的规范化、标准化势在必行。文中针对此种需求介绍了电子地形图符号体系和符号标准化的研究现状,分析了电子地形图符号体系中存在的主要问题,详细阐述了电子地形图符号体系构建的基本原则、内容以及体系结构,并且结合示例进行了说明,为电子地形图符号体系的研究提供了一些思路。
Along with the development of digital mapping technology, the application of electronic map increases day by day. In order to guarantee the uniformity and the accuracy of cognized geographic information, and achieve the information and resources shared, it is urgent to promote the guideline or standard for electronic topographic map symbol. This article introduces in view of this kind of demand the present research situation of electronic topographic map symbol system and standard for electronic topographic map symbol, analyzes the main problems exist in electronic topographic map symbol system, elaborates the principle of constituting electronic topographic map symbol system, the contents and system structure to establish an electronic topographic map symbol system, and combines the example to show. The article will provide some research thoughts for studying the electronic topographic map symbol system.
