摘要
针对GIS网络分析中心服务范围确定中存在的整体地物被服务范围多边形切割,和不能正确表达拓扑实体间的真实关系等两个问题,将服务范围分解为作用范围和服务区,并分别设计了确定方法。
Aimed at two problems that the integrated object is divided by service region polygon and the result cannot correctly express true relationship between topological entities exist in center services construction of GIS network analysis,service region is divided into bound of force and service area,and the construction methods of the two concepts are designed in this paper.Research conclusions can provide ideas and preliminary solutions for research of center service area that considering topology between graph of center force and service objects.
