This paper which starts from the actual needs , directed by the theory of cartology analyses all kinds of requires and functions for dmges , and create the spatial data model of the software system , combining the new generation programming technology , taking the oo software modeling , analysis , design method , it realized the collection , display of digital map data and the building of map denotation library , hi the end , this paper put forward the go - on research in future 本文从数字地图制图的实际需要出发，在地图学理论的指导下分析了数字地图图形编辑系统的各种功能和需求，并建立了软件系统的空间数据模型。结合新一代的计算机程序设计技术，采用面向对象的软件建模、分析和设计方法实现了地图数据的采集、显示、编辑、地图符号库的建立。最后提出了需要进一步研究和完善的内容。
After analyzing and study two transitions of map to spatial data and spatial data to map , the author thinks the spatial data capturing is a loss map information process , and for map production firstly symbolize from spatial data , then reinforce the map information . the map production model ( mpm ) is the summary of all kinds of map production . the integration model is the best model in mpm and it infers that " spatial data first , map second " is the production process 提出了“静态数字制图”和“动态数字制图”的概念，论述它们各自特点和研究方法，并提出地图制图和空间数据生产都属于“静态数字制图” ；通过研究地图和空间数据的相互转换过程，发现空间数据生产是地图信息损失的过程，根据空间数据来进行地图生产必须先实现地图符号化，然后再进行地图信息的补充处理；本文提出的“地图生产模型”是现有各种数字化生产模式的基础，从理论上论证了一体化生产模式是最优模式，推导出“先空间数据生产，后地图出版”的一体化生产流程，并归纳总结了当前数字化生产的4种基本生产模式和9种应用情况。
The map symbol base system is one of the basic functions of geographic information system . as a basic research , it developed rapidly with the development of information technologies . under the guidance of the map symbol and software developing method theories , using the thinking of " design pattern " , this paper put forwards a design method of the two dimensions symbol editor . lt is researched from the theory to the practise . the topics of this paper as follows : 1 this paper not only discussed the question of symbol design system , but also discussed the background and contexts of research based on the map symbol theory and the researching actuality 2 by introducing the background of map symbol base ' s technology , this paper puts forward a feasible developing method and introduces some developing tools , such as unified modelling language , rose etc . 3 地图符号库系统是地理信息系统( gis )中不可缺少的基础功能模块之一，它作为gis基本的研究课题，随着信息技术( informationtechnologies ， it )的发展也在迅速发展着。本文在地图符号和软件开发理论及组件技术的指导下，运用先进的“设计模式”思想，提出二维符号编辑系统的设计思路，并且从理论到实践进行了较为全面系统的研究和探讨。其主要内容包括： 1 、从地图符号理论基础和研究现状出发，对目前符号编辑系统存在的问题、课题研究背景和研究的内容进行了探讨。
For publishing paper map , some approaches , for examples , area feature symbolization , feature covering , making mask and so on , are accomplished on the process . it is the second key that spatial attribute database management is applied in digital mapping . when a user adds or changes a feature , its attribute and symbol will be changed together 本文指出解决空间数据的地图表达是实现一体化生产模式的第一个关键，其中地图数据符号化技术贯彻全部过程，实现了基于地图符号的空间数据生产，并在地图出版阶段，通过面状符号配置、要素压盖、蒙片等地图出版处理技术，实现地图出版；本文把属性管理技术应用在地图制图中，实现了属性数据库支持下的地图编辑。
The paper introduces the organizing program of the system in detail and the method for customizing microstation ; expatiates upon the building of map symbolic library and the automated realization process of map border decoration ; explains the design principle of input and output function and analyzes the technical methods for developing important digital map editing functions 文中详细介绍了系统的组织方案和定制microstation的方法；阐述了地图符号库的建立和图廓整饰的自动实现过程；说明了输入输出功能的设计原理；分析了开发数字地图重要编辑功能的一些技术方法。
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。
According to the fact of existing mapping relations between cartographic region and the subjective cognition structure , this paper brings forth the definitions of imitative map symbol and virtual map symbol , studies the rule of their evolution , puts foward the mathematical model for maps of planning and forecasting as well as the definition for geo cyber space 摘要根据从制图区域到主体认知结构，从主体认知结构到二维平面之间存在映射的关系，给出了模拟地图符号和虚拟地图符号的定义，探讨了其演化规律，并给出了规划和预测地图的数学模型以及地理虚拟空间的数学定义。
