| 摘 要： | 为了适应软件组件化潮流，新一代地理信息系统-组件式地理信息系统越来越成为今后GIS发展的趋势。在阐述组件式地理信息系统的概念和技术的基础上，讨论了组件式地理信息系统的发展历程和特点及其在实际的地理信息系统平台中的应用情况，在此基础上较为深入地介绍了MAPGIS组件式地理信息系统的设计开发原理和实用特点。针对MAPGIS组件开发平台多层次的体系结构，进行举例说明，按照其功能把组件分成不同的类型，分别实现相应的操作。然后详细地阐述了利用GIS组件进行应用系统开发的优点和方法：各个模块之间既可相互关联共同处理数据，又可独立操作互不影响，可以实现高效无缝的系统集成。

| Abstract: | The concept and the technological foundation of COMGIS are discussed with examples. Further, some differences between COMGIS and traditional GIS, as well as some characteristics of COMGIS are studied. Based on this, we also set up a sample framework solution and development in MAPGIS platform. In this segment, some essential ideas of design and development of MAPGIS components are introduced. With some explicit charts, we can understand the hierarchy of system entirely. In next step, this paper formulates some advantages of development GIS application by using MAPGIS components. At last, the paper introduces major functions and characteristics of COMGIS in some application aspects. At the same time, an amplitude trend of COMGIS development and application is specially introduced. |
