Research And Implementation Of The High-Speed Rail Line Exhibition System Based On Webgis

In recent years, high-speed railway in China has achieved leapfrog development, made remarkable achievements. China has become the world’s longest high-speed railway operating mileage and fastest growing countries. The railway has distinct geographical distribution characteristics. In the development process of railway, a large number of railway spatial data, including lines, trains, railway stations, bridges, tunnels, communication signal equipment, are generated, which require the introduction of geographic information system to manage spatial data information.In this paper, the database and WebGIS technology were used synthetically. Web rich client development technology and WebGIS technology were combined to study the effective management mechanisms of the railway line data. Based on the line GIS model, high-speed rail system involved relevant line data were organized and managed effectively, and supported by this, high-speed rail line exhibition system was developed, furthermore, line data visualization exhibition and query functions were realized.Firstly, the research background and significance was introduced, the current development of China’s high-speed rail and the application of GIS technology in the domestic and international rail system were reviewed, and related development technologies were introduced. Then, the function and requirements of the target users and system were analyzed. System use case analysis was presented with using UML. Based on requirements analysis, the overall architecture of the system was provided, and the various modules and functions of the system were designed. The design of spatial database system, the property database and multimedia database were completed. Finally, system development environment is analyzed; the implementation of the system function modules was discussed in detail, and the effect of the system operation was explained.The high-speed rail line exhibition system based on WebGIS presented in this paper can realize management and query of the business data and multimedia data on high-speed rail line elements, and display a two-dimensional map of train running simulation. The exhibitionsystem made useful exploration for WebGIS technology used in the development of high-speed railway information system.
