| 摘 要： | 地理模型分布式集成是虚拟地理环境研究的主要内容之一。在分布式系统中多采用XML作为数据交换的统一标准,以解决多种信息在网络空间的表达和传输。本文在VisualC#.NET平台下开发了一个通用的模型数据定义编辑器,用XML来统一描述多源异构的地理模型数据,以实现模型的共享和集成。提供了直观式图形界面,可满足无程序背景的设计人员的需求,使智能化的模型集成成为可能。以地下水模型分布式调用为例,验证了此编辑器的有效性和易操作性。

| Abstract: | The distributed integration of geographical models is one of the main objectives of the virtual geographical environment. In distributed systems, the format of XML is mostly adopted as a unified standard to express and transfer all kinds of information in the network. This paper develops a universal editor for models data defining under the platform of Visual C#.NET. The format of XML is adopted for describing the multi-source heterogeneous data so as to actualize the integration and sharing of the geographical models. Also the intuitionistic graphical interface is provided, which satisfies the designer without procedure background and makes the intelligent integration of models possible. The groundwater models are distributively invocated with this editor. The result shows that this editor is effective and easily operable. |
