道路网示意性地图的渐进式综合研究

Progressive Generalization Research of Schematic Road Network Maps

  • 摘要: 研究并总结了示意性道路网地图的制图规则,量化了约束条件,提出了一种道路网渐进式图形简化方法和移位方法,并研究了拓扑关系检查方法。在具体实验中,通过对道路网上点的分类,依据约束条件,快速生成有效的道路网示意性地图,同时保证了原始道路图与示意性道路图之间的拓扑关系一致性。

     

    Abstract: The cartographic design criterias of schematic road network map are analyzed and summarized,a set of quantitive constrains are set up,and a new road network generalization method including progressive selection and displacement is proposed.And topological checking method for road network are studied.Based on these constrains,the points in a road network are classified,and a satisfied and effective schematic map is designed in a concrete experiment,while keeping the topological consistency of the road network between original and schematic map.
