摘要
GIS是综合处理和分析地理空间数据的一种技术系统。文中基于GIS系统,根据不同的要求,获得了到达指定目的地的最短路径,并给出了路径的长度;在网络中指定一个地理中心,分别求出在不同距离、时间的限制下从起点到该地理中心的最短路径;给定访问顺序,按照要求找出了从起点出发,逐个经过访问点,最终到达目的地的最佳路径;研究了阻强的设置对最佳路径选择的影响。
OIS is a technology system to comprehensively analyze and deal with the geographical spatial data .Based on GIS, according to different demand, firstly, the shortest path to designated destination and its length are given; secondly, the shortest path from starting point to a designated geographic center in network is given respectively limited by different distance and time： thirdly, visiting sequence given, the shortest path from starting point to destination is found; finally, resistance setting＇ s influence on choice of shortest path is studied.
