CAD/GIS集成方法在土地利用数据管理信息系统中的应用

Application of CAD/GIS Integration Method in Land Use Data Management Information System

随着信息技术交叉快速发展,多种技术相互借鉴并走向融合,是当前信息科学应用领域中的必然趋势。本文首先分析了CAD/GIS集成应用的必要性,接着阐述了CAD/GIS数据集成与功能集成的一般方法,以及在应用中存在的主要问题。然后,给出了一种数据解译器组成结构,可以有效地实现CAD/GIS数据的无缝集成。同时,提出了以组件技术实现CAD/GIS功能紧密集成的概念模式。最后,以土地利用数据管理信息系统开发为例,验证了CAD/GIS集成能明显提高信息系统的整体效能。

With rapid and intersectional development of information technology, technologies borrow from each other, and tend towards fusion. Firstly, this paper analyzes the common methods of data integration and function integration for CAD/GIS, and the problems existed applications. Then, a constitution structure of a data translator is given, which can efficiently accomplish seamless data integration for CAD/GIS. Moreover, a concept mode to realize closed function integration for CAD/GIS based on component technology is presented. Finally, taking the development of landuse data management information system as an example, it is testified that the CAD/GIS integration can improve efficiency of thematic information systems remarkably.
