本次任务完成时间：2019年1月16日
开发工具与关键技术：开发工具：SuperMap iDesktop 9D、SuperMap iServer、.net，关键技术：拓扑构网
完成模块功能：最佳路经查询
一、地图与拓扑构网
首先在SuperMap iDesktop 中新建SQL的数据型数据源，然后在资源导入所需要的数据集，通过点、线、面构建出所需要的地图。
1．创建好地图，进行拓扑构网，其中所说的构网，也就是有每一条的线数据组成的网格。在SuperMap iDesktop点击交通分析，点击拓扑构网选择选择构建二维网格。
2、构建二维网格数据集，点击左上角的新增按钮，跳转选择线数据集页面，选择所需要的线数据集进行构建二维网格数据。
3、二维网格构建完成后，点击数据的线拓扑处理，弹出模态框点击确定进行线数据处理。
4、交通分析，点击最佳路经进行刺点，然后进行最佳路经分析点击执行，通过三个站点来分析路线，得出最佳的结果路经。
二、功能实现
1、在SuperMap iDesktop处理完所需要的数据，然后在SuperMap iServer中重新发布地图。

2、上面就就是个人样式与实现功能代码。（在后面有完成后的功能效果图片）
3、点击站点按钮进行定点，然后通过点击提交按钮进行最佳路经选择。
