制图综合中河流与建筑物拓扑冲突处理方法
Method of handling topological conflicts between river and building in map generalization
摘要
Abstract
Cartographic generalizations make it more productive while deriving smaller-scale features from larger-scale topographic maps. Nowadays, cartographic generalization operators are more widely used than ever, such as simplification, smooth, etc. Sometimes, these operators may produce errors. For example, if a river at larger scale is smoothed improperly, then a building by the river side would drop into the water from the perspective of a map user. That is called an inconsis-tency, i.e., conflicts happen to a river and a building. Hence, a methodbased on morphing technique is proposed to handle these conflicts. Firstly, the boundary of a river at a larger scale and its corresponding boundary which is produced by gener-alization operators are extracted. Then, a conflicting zone which is covered by a building is excluded from the area ringed by both river boundaries. Secondly, morphing transformations are performed from boundary of alarger-scale river to the other side. Thirdly, with respect to the distance constraint, an optimal river boundary is interpolated. At the end of this paper, experiments demonstrate that the proposed method provides a promising solution for eliminating topological conflicts between a river and a building.关键词
