摘　　要：地图符号是地图语言的重要组成部分,是可视化表达空间地理信息的基础工具。本文主要研究了山东省1∶50000 DLG数据地图符号库的设计、制作及自动符号化的实现方法,并以ArcMap为平台,通过ArcOj ects组件二次开发的方式,建立1∶50000标准地形图制图系统。系统可以实现快速自动制图及输出,有效提高了数据的规范化管理和社会化信息共享服务,具有极其重要的应用推广价值。Map symbol is an important part of map language and is also a basic tool for visualization of spatial geo graphic information.This paper studied the design and implementation method of map symbols database and automat ed symbolization based on 1∶50000 DLG data of Shandong Province.And we successfully established a standard top ographic mapping system which runs on ArcMap platform through secondary development of the ArcObjects compo nent.This system can realize rapidly and automated mapping and output which can effectively improve the standard ized management for data and sharing service for information of socialization,and it has the value of popularization.
