摘要
在地图制图综合中必须保持不同尺度同一区域地图要素之间拓扑关系的一致性,但目前有关的一致性评价方面的研究较少,本文讨论了不同比例尺地图中居民地与道路之间拓扑关系一致性的模糊评价问题。从制图规则和视觉限制的角度,分析了多尺度地图表达中居民地与道路之间的应该保持拓扑关系的一致性的几项规则;基于模糊数学理论提出了制图综合中拓扑关系的一致性评价模型,并通过一个简单实例证明了该方法的可行性。
The field of cartographic assessment has been less studied than the process of cartographic generalization itself,but it is very important to keep topological relation consistent in multi-scale map representation.In this paper,the fuzzy evaluation methodology for the consistency of topological relations was proposed.Taking roads（including railway）and residential areas for examples,from the viewpoint of the spatial cognition and cartographic rules,some standards that should be met in order to keep topological consistency in different map scales were analyzed.Based on the fuzzy set theory and the classification of map object types,the consistency evaluation model of topological relations was established.Finally,the feasibility of the method was proved through a simple example about how to evaluate the local topological relations between roads and residential area.
