基于.NET和ArcIMS的WebGIS设计与实现

Design and Implementation of WebGIS based on .NET and ArcIMS

在分析了ArcIMS的体系结构和开发方式特点的基础上,利用ArcIMS中的Servlet连接器和ArcXML语言的优点,在.NET环境下对ArcXML的生成进行封装,并结合ASP.NET技术设计了通用的WebGIS控件.该控件较好地实现了WebGIS中表现层与服务层的分离,可以方便地进行二次开发和与其他.NET系统集成,从而大大降低了WebGIS在.NET平台下的实现难度,并使系统具有了更好的可扩展性.通过在无锡市环境地理信息系统的应用实例介绍了实现过程.

Having analyzed the architecture and developing methods of ArcIMS , made use of the advantages of Servlet Connector and ArcXML language, and packaged the generation of ArcXML in the context of .NET and in combination of ASP.NET technology, we design a general WebGIS controller. This controller can well separate the server layer and the present layer, and easily make the secondary development and integrate with other .NET system, and thus greatly reduces the difficulty of realizing WebGIS in the platform of .NET and provide the system with a better expansibility. The realizing process is introduced in the application example of Wuxi EGIS (Environment Geography Information Sytem).
