摘要: 针对传统弧段-结点模型不能完整有效地表达道路网的几何与属性特征,提出了基于动态分段的道路网示意性地图综合模型。即按照道路网属性一致性、图形延续性等原则组织道路网路径实体,以完整路径线状实体为单元,采用基于路径的道路网图形简化、移位一体化处理方法,实现道路网地图快速示意化。实验对比分析结果表明,基于动态分段的道路网示意性地图表达更加清晰、有效。

Abstract: Lines do not represent the routes completely and effectiveness based on arc-node model.In this paper,a new model generalization of schematic network maps based on dynamic segment is proposed.Routes are constructed according to the road segment attribute similarity and geometry continuous.Based on route networks,a new method comprising shapes simplification and displacement is proposed to schematize road network quickly.A case study for schematic map was carried out and analyzed.Initial experimental studies show that this approach is more effective in evidence on making features maximum clearly on screen.
