WebGIS中间件的开发与应用

Development and Application of WebGIS Middleware

如何快速搭建网络地图应用和基础地图系统是当前地理信息科学领域的研究热点。通过对W ebG IS原理的分析,提出了利用Java A pp let技术开发W ebG IS中间件的思想,并应用于高速公路信息可视化系统中,结果表明,该中间件可大幅度地提高系统开发效率,降低开发难度。

Presently a research focus in geographical information science （GIS） is how to quicken the step to build a map application and a basic map system based on Internet. Through analyzing the principles of WebGIS, this paper puts forward an idea of using Java Applet technology to develop WebGIS middleware, and applies it to the highway information visual system. The result shows that this middleware can not only greatly improve the efficiency of the system development, but also reduce the difficulty in the system development.
