摘要
讨论了一种地理信息系统空间分析算法——最短路径分析,然后利用最短路径结果,采用表上作业法将灾害救援物资进行优化,给出最优调运方案。
This paper discussed a kind of spatial analysis algorithm of GIS,which is the shortest route analysis.Then it optimized the rescue supplies using form operation method based on the result of the shortest path,and selected the optimal transportation scheme.
