本人载网站开发gis,游自编的最短路径查询程序，速度特快，3万节点，35000条路全部遍历，只需1秒。现将最短路径的思路告诉大家，希望大家在优化，并用不同语言编制，我正在学delphi,准备用delphi做成库，本例以由拓扑关系的arc/info 文件为数据源。其中a1,b1,c1是以fnode排序生成的数组，a1对应fnode,b1对应tnode,c1对应length,同样a2,b2,c2,是以tnode 生成的数组。Indexa1是对应某一起点与其相连的终点的个数，indexb1时对应某一终

Mapx delphi用于地图中的定位查找,Find Location Mapx delphi.why not enough length can t upload. fuck!
