摘　　要：为实现煤矿WebGIS在移动智能终端的可视化,以及办公人员可随时随地进行移动办公,提高煤炭企业工作效率,基于HTML5技术进行WebGIS移动客户端设计。采用前端框架与.NET开发技术实现移动客户端实时数据显示,在前端页面显示方面采用一张图分层显示设计思想,以不失真的SVG矿图为静态底图,需要变化的元素采用HTML5中的Canvas实现动态绘图,并且在不影响渲染结果的情况下优化SVG代码与页面显示速度。实践结果表明,该系统大大提高了客户端的网页显示效率,缩短了显示时间,可实现随时随地移动办公,查询、浏览各类专题图与属性数据,并在智能移动终端实时获取生产、调度、灾害报警、审批代办等信息。In order to realize the visualization of coalmine WebGIS in mobile intelligent terminal so that office workers can do their offices anywhere and anytime and the work efficiency of coal enterprises can be improved,this paper presents a WebGIS mobile client design idea based on HTML5 technology,front-end framework and.net development technology to realize real-time data display of mobile client.It adopts front-end framework and.net development technology to realize real-time data display of mobile client.Before the front page display,a coal graph is used to display the design idea and make the real SVG mine map as a static base;the changing elements implement dynamic drawing in HTML5 Canvas.The SVG code and page display speed are optimized without affecting the rendering results.The practical results show that the system greatly improves the display efficiency of graphs for clients.This system greatly improves the efficiency of picture display,shortens the display time,enables the staff to work anytime and anywhere,browse various kinds of thematic maps and attribute data,and access production,scheduling,such as disaster alarm,the examination and approval agency information and the intelligent mobile terminal.The office efficiency of coal enterprises is thus improved.
