摘要
采用最短路径算法结合GIS的方法,对影响土地定级的障碍物问题进行研究,提出建立通行点网络的办法。结果表明:采用这种方法得到的扩散界面图更符合实际情况。
By combining the shortest path algorithm and GIS, the effects of the problem of obstacles on land grading were studied and the method of building traffic point network was put forward. The results showed that the diffuse interface map obtained by using this method was more accordant with the actual situation.
