摘　　要：基础地理信息数据在地理信息系统中一般表现为点、线、面等几何类型,采用要素符号化的方法实现地形图的表达效果。由于地形图应用领域的不同,有些只需要将地形图作为简单的背景图使用,针对这些应用,采用符号化方法生成标准地形图负载太大,效率降低。本文提出了基于ArcGIS平台的图幅级整体建库方法,设计实现了相应算法,并开发了应用软件,避开了地形图要素符号化的问题,实现了ArcGIS环境下地形图的表达效果,在实际工作中得到了应用。In Geographic Information System,fundamental geographic information data is generally represented such geometries as point,polyline or polygon and Its expression effect is implemented by the method of symbolic feature.Due to the different to topographic map application fields,some only needs topographic map as a simply background,so the method of symbolizing fundamental geographic information data no longer applies.In this paper,sheet level whole build database method based on ArcGIS platform is proposed,which algorithm is Designed and implemented,and application software is developed.So the topographic map feature＇symbolization is avoided,and the topographic map＇s expressing effect is realized in the ArcGIS environment.This method has been applied in the practical work.
