【摘要】 目的研究Web GIS的点之记可视化在地铁工程中的应用。方法采用B/S三层体系构建系统架构,其中应用服务器调用ArcGIS Server核心组件发布地图,Web服务器响应用户请求,用户浏览器端完成点之记的可视化显示。结果在网络上实现了点之记的可视化查询、浏览以及点之记资料的分布式管理,能够实时更新点之记并展现点位多方位多角度地理图像。结论基于WebGIS的点之记可视化为地铁施工中测量人员查找并选择合适控制点提供了很大帮助,能够确保点之记资料的现势性和准确性,大大提高测量人员的工作效率。更多还原

【Abstract】 Aim To research the application in subway project of visualized description of station based on Web GIS.Methods Three-tier B/S is adopted to design system architecture,in which the application server uses core components of ArcGIS Server to publish map,web server responds to user requests,user browser shows visualized description of stations.Results Visualized query description of station on the net,and management and real-time update records can be distributed,and multi-angle geographical images can be presented.Conclusion Visualized description of station based on Web GIS provides great help to the survey crew in finding and selecting appropriate control points,ensure up-to-date status and accuracy of the records,greatly improve working efficiency.更多还原
