| 摘 要： | 随着计算机技术和网络技术的飞速发展及其在地理信息领域的应用,电子地图逐渐扮演起主导地图产品的角色.电子地图有众多的产品形式,以面向多用户为主要任务的通用型大区域矢量电子地图是其中重要的一支,其数据表现为电子地图数据库,其功能则表现为对数据库的快速浏览、检索、维护、更新以及分发.通用型矢量电子地图的设计原理及方法同传统地图和其他电子地图的设计有较大差别,具体表现为在地图符号系统的逻辑设计,空间数据可视化的表现手段,地图数据库系统的结构化设计及地图数据的应用设计等方面的不同.本文以沪苏浙电子地图的开发实践为基础,对上述问题进行了探讨,并从地图设计的角度总结了通用型矢量电子地图的设计原理与方法.

| Abstract: | With the rapid development of computer and internet and its application in GIS field, the electric map gradually play a role as leading map products, electric map has many products, .the common vector electric maps of large area which faces more users is an important branch, its data manifests electric map database, its functions manifests quick browse, index, maintenance, update and distribution. The design principle and method of common vector electric map is different with the design of other electric map, its incorporation is the logical design of map symbol system, the represent measures of space data visualization, the structured design of map database system and the application design of map data. This paper discusses the above problems basing on Husuzhe electric map exploring practices, summarizes the design principle and method of common vector digital map on map design. |
