摘　　要：新形势下,为满足地图保障服务的新需求和高要求,江苏省基础地理信息中心建设了基于制图表达知识规则的多尺度地图数据库,用于生成符合印刷要求的地图产品。在多尺度地图数据库建设过程中,要重点解决已有的完善数据成图时出现的制图符号冲突,即地图数据经过制图综合和可视化表达后,仍存在符号冲突。目前,符号冲突处理的自动化程度很低,为达到制图规范的要求,需要进行大量的人机交互工作。本文结合制图规则,利用协同移位算法,建立了符合实际需求的符号冲突处理方法模型,解决了地理数据库向地图数据库扩展过程中地图符号冲突问题,提升了多尺度地图数据库建设中符号冲突处理的质量和总体效率。In order to meet the new and strict requirements of map support services under the new situation,Jiangsu Geomatics Center is constructing multi-scale map database based on cartographic rules for printed map production.The key point to the process of database construction is the cartographic symbols conflict of the existing result data,which has been processed by map generalization and visualization.At present,symbol conflict is processed with low automation,to satisfy the standard requests,a lot of human-computer interaction is needed.In this paper,a symbolic conflict processing model,based on the cartographic rules and the collaborative displacement algorithm,is established,which solves the problem of symbolic conflict in the process of extensions from geographic database to map database,and improves the quality and overall efficiency of symbolic conflict processing in the construction of multi-scale map database.
