摘要： 针对传统WebGIS实现方案存在响应速度慢、用户体验差等不足，提出一种新的WebGIS设计应用方案。该方案采用Web2.0核心的AJAX技术，利用XML在网络应用传输中的优势，在Google Maps平台上通过XMLHttpRequest对象异步调用XML数据实现动态加载地理信息。应用结果证明，该方案提高了WebGIS应用程序的效率，具有访问快捷，且在浏览器和服务器端能实现异步通信、定制和扩充的特点。

Abstract: Aiming at shortcomings of slow response and poor user experience existing in the traditional WebGIS application, this paper presents a new WebGIS design framework with core AJAX technology of Web2.0 and XML data transfered in the Web application. Based on Google Maps platform, the application uses the XMLHttpRequest objects which call the XML data and load the geographic information dynamically. Applied result proves, the scheme improves the efficiency of WebGIS application, it can be accessed quickly, customized and extended, and make asynchronous requests between the browser and the server.
