摘　　要：城市大比例尺地形图是地理空间框架数据库的重要组成部分,其要素形式较多、数据关系复杂,目前城市大比例尺地图自动缩编方法还不够成熟,缩编效果不够理想。本文结合成都市大比例尺地形图缩编工作需求,梳理总结大比例尺地形图综合规则,研究综合规则形式化描述方法,构建地形图缩编的综合规则库,基于标准的地形空间数据库和综合规则库设计开发成都市1∶2000地形图自动缩编系统,并应用于实际项目数据生产。工程实践证明,基于自动综合规则库的城市大比例尺地形图缩编方法可显著提高生产效率,有广泛的推广应用价值。Urban large-scale topographic map is an important part of geospatial framework database.Because of many elements and complicated data relation,the automatic zooming method of large scale map is not mature enough and the effect is not that ideal at present.Combined with the demand for large-scale topographic map generalization of Chengdu,this paper summaried the generalization rules of large-scale topographic maps,studied its formalized description methods,constructed the generalization rule library for topographic maps,designed and developed 1∶2000 Topographic Map Automatic Generalization System of Chengdu City based on standard terrain spatial database and generalization rule library,and applied it to actual project data production.The engineering practice shows that the method of urban large-scale topographic map generalization based on automatic generalization rule library improves operational efficiency significantly and has wide application value.
