MapX在三峡库区流域图中的应用与研究

Application and Study of MapX in the Electronic Map of Three-Gorge Reservoir and its Vicinal Valley

组件式软件技术,是面向对象技术和分布式计算在软件工程中应用的深化。基于G IS组件的应用系统能与管理信息系统紧密集成,它为G IS应用系统的开发提供了一个完好的方法。着重分析基于MapX的开发模型及其在三峡库区流域图中的实现,讨论基于MapX绘制等雨量线的动态链接库的设计,并简要介绍了MapX应用程序的发布。

Component-based software technique is the further application of object-oriented technique and distributed computation in software engineering. The application system based on GIS component technique is able to integrate with the management information system （MIS） , and it provides a good approach for the development of GIS application system. This paper focuses on the analysis of development model with MapX and implementation of the electronic map of Three-George reservoir and its vicinal valley. Besides it discusses the design of DLLs used for isohyet and briefly introduces the distribution of application software of MapX.
