地图图形目标之间基本空间关系抽象的规律
Rules of Basic Spatial Relations Abstraction Between Map Graphic Objects
-
摘要: 以地图自动综合为目的,定义了空间目标的几种基本空间关系。总结了道路、水系、居民地等要素之间存在的典型空间关系,着重讨论了它们之间空间关系抽象的规则,为地图自动综合中有效保持空间关系的一致性提供必要的理论基础。Abstract: For cartographic automatic generalization,the basic spatial relations between spatial objects are defined;and the typical spatial relations between map features such as road,water system and settlement are concluded.The abstraction rules of basic spatial relations between these spatial objects are discussed.It affords the essential theoretical fundamental to maintain spatial relation consistency in effect in cartographic generalization.
