Based on the research of the conception and the theory of designing about electric map , a system for making and applying military electric map is developed in this paper . the achievements can be summarized as follows : introducing the relative technology about the electric map and discussing the design , realization and composing of military electric map system . discussing the special require of electric map and particularity of making electric map symbol , and making an in - depth study on realization of map symbol base and plotting module 本文重点讨论了屏幕上电子地图显示的特殊要求，以及在电子地图条件下符号制作的特殊性和应该注意的问题，提出了电子地图条件下符号设计的原则，在此基础上设计了合理的数据结构、采用复合文档技术进行了地图符号库的设计与实现，并以符号库为基础，针对军标符号的特点，建立了军标符号库，实现了军标符号的制作以及军事标图模块的研制。
Based on the main idea of " the map display of comgis " , the concept and technological foundation of comgis , the theory of component ( com ) , and component - based development ( cbd ) are discussed separately in this paper ; and some products of comgis in existence are studied . also , system designs and development models of the map display of comgis have been presented based on recent practices , including the structure of data and map symbol library 本文以“组件式地理信息系统的地图显示”为核心，分别阐述了组件、组件gis和组件式软件开发的理论和方法，对现有组件gis产品进行了研究分析，重点设计实现了地图显示的组件，其中涉及到了数据结构的定义和地图符号库的建立，以及导航功能的设计实验等内容。
