基于AJAX的WebGIS应用

Study on WebGIS based on AJAX

针对目前WebGIS中所存在的问题,介绍了AJAX方法的概念和内涵,提出了基于AJAX方法构建网络地理信息系统的思路。并以森林资源信息网络发布系统的原型开发为例,阐述了该方法的优点和一些关键技术。结果表明通过AJAX方法的使用不仅能够快速地实现森林资源信息的网络发布功能,而且能够很好地改善WebGIS应用中以地图为载体的地理信息的网络传播和显示速度,带来丰富的用户体验。

In order to overcome the problems associated with WebGIS,this paper introduces the concept and operational principle of AJAX method and proposes to build a WebGIS based on AJAX method.With the development of a forest resources information web publishing prototype WebGIS system,this paper discusses some key technologies and advantages of AJAX method.The result shows that AJAX method not only can easily realize the forest resources information web publishing,but also can greatly improve the WebGIS＇s overall performance.
