| 摘 要： | 通过介绍Ajax技术,研究基于Ajax技术的WebGIS原理和实现方法,并和WebGIS的其它不同实现方法进行了对比。相对基于其他Web技术的WebGIS来说,基于Ajax技术的WebGIS具有不受浏览器限制、访问速度快捷、开发方便、费用低廉、可以实现功能定制和扩充、可以在客户端和服务器之间异步通讯等优点。因此,基于Ajax技术的WebGIS可能成为未来WebGIS发展的主流方向。

| Abstract: | A study on WebGIS and its implementation that is based on Ajax technology is presented in this paper.Then a comparison has been made between WebGIS based on Ajax technology and those based on other technologies,and reaches the conclusion that WebGIS based on Ajax technology has the following advantages:it doesn't limited by the various web browsers,and can be accessed quickly;it can be customized and extended;it can make asynchronous requests between the client and the server and is cheaper for development. |
