摘要
主要介绍基于 GIS栅格数据计算最优道路路线问题的算法设计原理和实现方法 ,它主要是根据坡度分级费用、最大坡长、最大纵坡和选线范围等限制条件 ,运用费用栅格矩阵法计算最优道路路线。最后给出一个示例 。
The design principle of algorithm and the way of implement on calculating optimal road rout based on grid data of geographic information system (GIS) are mostly introduced in this paper The algorithm has its own particular characteristic, it resort to the way of cost grid matrix to calculate the optimal road rout, according to conditions of restriction such as the costs of slope classification, maximal length of slope, maximal longitudinal gradient and range of road routing etc An example to support the exactness of result calculated by the road routing model is given in this paper.
