基于组件对象模型的校园地理信息系统的实现

基于组件对象模型的地理信息系统 (SGIS)平台比大型的基于应用程序的地理信息系统平台具有小巧、灵活的优势。系统采用小巧快速、易于使用的 GIS软件平台 ;系统开发环境 ,选择了高效的、完全支持 Active X控件、对数据库也非常支持的应用 ,完全可视化的、面向对象的编程环境 ,有利于提高系统的开发效率 ,加快系统的开发进度 ;用它能够开发出一流的用户界面 ,使系统易于使用。应用地理信息系统技术 ,能高效、直观、综合地管理空间和属性信息。它比单纯的基于属性数据库的管理信息系统具有更直观、信息容量更大的优点。结合实际给出了一个中等校园地理信息系统 (SGIS)的实现方案 ,具体描述了其空间模型、系统模型

Implementation of geographic information systems based on groupware object mode for school campuss

The flat roof of a geographic information system based on groupware object mode is smaller and more flexible than the big geographic information system flat roof based on application. This system adopts the GIS software flat roof which is small, fast, and easy to use. The system development enviroment adopts the programming environments that is efficient and fully supportive of ActiveX control and the data\|base. And the programming enviroment can be seen absolutely and is objet\|oriented. The system is in favor of improving the system's development efficiency and quickens its development progress. It can develop the best user interface and makes the system easy to use. The using of SGIS can manage space and attributive information in high efficiency straitly and comprehensively.Compareed with the administration system based on attributive databases,this system is more straight and has bigger information content. In combining it with practive,we give an SGIS realization plan for a mid-sized school campus with its space model and system model described in detail.
