Ajax技术在WebGIS系统中的性能优化研究

Performance optimization research of Ajax technology used in WebGIS system

为了提高WebGIS系统地图图像数据响应效率,将Ajax技术运用于WebGIS系统开发中,重点分析了基于Ajax的数据交互及方法实现,Ajax的动态数据请求在很大程度上解决了WebGIS数据显示不流畅的问题,具有广泛的应用价值。

in order to improve the response efficiency of map image data in WebGIS system, Ajax technology was used in development of WebGIS system. The Ajax based data interaction and implementation method are analyzed emphatically in this paper. Ajax dynamic data request solved a problem that the WebGIS data display is not smooth to a great extent. It has a wide application value.
