【Abstract】 This paper introduces the GIS’s development process and webgis’s characters,proposes the framework and technology which used in this paper based on the analyses of webgis’s typical framework,application pattern and relate technology.Then,the bus net topology model is built based on other people’s research and the analysis about bus net,the optimization path algorithm of bus interchange on the improvement of normal Dijkstra algorithm.Finally,a bus interchange experimental system is realized with ActiveX based on full design of the system.更多还原
