本程序是K条最短路算法测试程序,陈艳艳老师的K条路算法。程序求3条最短路，约束条件值可以设定,约束值越小，多路径共用路段越多。-Article K of the procedure is the shortest path algorithm to test procedures, Yan-Yan Chen K teacher path algorithm. Procedures for the three short-circuit, constraints can be set value, the smaller the value constraint, multi-path section of the more common.

应用背景物理大地测量学中，经常用到两点间的方位角，已知球面两点大地经纬度坐标，求解两点间的球面方位角。假设地球为球形进行的计算。关键技术通过两点的大地经纬度坐标，计算两点球面坐标方位角。需要输入文件INPUT，输入格式 纬度 经度 大地高（或正高），可以是一组数据也可以是连续的多个数据，排列顺序是按列三列数据。计算出的方位角是以第一个点到第二个点的方位角。例如，假如序号为1,2,3,4……。那么求出的方位角为α1-2，α2-3，α3-4……。输出文件为fangweijiao.dat

交通GIS论文集,这是我在网上找的一些,再结合自己的一些东西,如果做交通行业的GIS,这是很好的参考资料.安装CAJ才能阅读-Traffic GIS collection, this is my online to find some, and then combine some of their own things, if the transport industry to do GIS, this is a very good reference. CAJ installed in order to read
