This thesis explores the paths used in the known data interface to achieve three path planning WebGIS design.This project will be based on open source Openlayers JavaScript library package,to achieve bus routes,car routes,walking routes queries,display,detailed route information display and analog navigation function.Problems encountered in the process and to explore solutions to achieve OpenLayers path planning based on actual implementation.%针对生活中常见的二维电子服务地图,本文探讨了运用于已知的路径数据接口在2.5D电子地图上来实现3种路径规划的WebGIS设计方案.该项目将基于开源的Openlayers JavaScript 类库包,实现公交路线、自驾路线、步行路线的查询、显示、路线详细展示以及模拟实现导航功能.就实际研发过程中遇到的问题探讨解决方案,实现了基于OpenLayers的2.5D电子地图路径规划.
