Research on Basic Issues of Automated Cartographic Generalization Based on Spatial Similarity Constraint

制图综合是地图制作、空间数据库建设、多尺度表达等必须面对的技术难题,一直以来是地理信息科学领域研究的重点和难点问题。为系统研究空间相似性约束的制图综合方法,在分析制图综合对空间相似性的影响机制基础上,给出一种基于相似性与清晰性的制图综合约束分类,剖析相似性约束的制图综合研究对象与内容。通过相关基本问题的研究,为探索空间相似性约束的自动制图综合方法奠定基础。

Cartographic generalization is a technical problem that must be faced in map production, spatial database construction and multi-scale expression. It has always been a key and difficult issue in the field of geographic information science. In order to systematically study the cartographic generalization method of spatial similarity constraint, based on the analysis of the influence mechanism of cartographic generalization on spatial similarity, a classification method of cartographic generalization constraint based on similarity and clarity is proposed, and the research object and content of cartographic generalization of similarity constraint are analyzed. Through the research of related basic problems, it lays the foundation for exploring the automatic cartographic generalization method with spatial similarity constraints.
