Schematic Road Network Map Progressive Generalization Based on Multiple Constraints

Multiple constraints for schematic road network map cartographic design are analyzed and summarized. Based on this, a set of quantitative criteria are set up and a new road network generalization method including progressive selection and displacement is proposed. Furthermore, topological checking methods for road networks are researched. Based on these constraints, the points in a road network are classified, and a satisfactory and effective schematic map is designed in a con- crete experiment while maintaining topological consistency of the road network between the original and the schematic map

为图解的道路网络的多重限制印射地图的设计被分析并且总结。基于这，一套量的标准被设置，一条新道路联网归纳方法包括进步选择和排水量被建议。而且，为道路网络的拓扑的检查方法被研究。把限制基于这些，在一个道路网络的点被分类，并且当维持在原版和草图之间的道路网络的拓扑的一致性时，一张令人满意、有效的草图在一个具体实验被设计。
