摘　　要：在WebGIS的浏览器端存在绘图效率差、不能直接支持矢量绘图等问题。为提高客户端的交互性和实时性,在解决浏览器不支持矢量绘图和渲染速度慢、存储空间小、传输速率慢这些问题的基础上,结合HTML5中的Canvas、WebSocket、WebStorage技术,构建了WebGIS实时客户端,有效地改善了客户端存在的问题,改善用户的体验。There are some problems in the browser side of WebGIS that the drawing efficiency is poor and it cannot supporting vector drawing directly. In order to improve the client＇s interactivity and real-time performance, this article solves those problems that browser doesn＇t support vector drawing and renders slowing, the storage space is small, and the transfer rate is slow. And on this basis, it combines with the HTML5 Canvas, WebSocket and WebStorage technology to build a WebGIS real-time client that can solve those problems in the client side effectively and improve the user＇s experience.
