摘要
将地理信息系统采用的核心技术归纳为地图分层、矢量抽象、空间数据与属性数据的划分三个方面，以此为基础，探讨了基于ＡｃｔｉｖｅＸ技术的ＧＩＳ平台。利用此类ＧＩＳ平台，结合校园信息的特点，使用面向对象的方法，抽象出校园图、楼、楼层、房间等通用概念，基于视图与视图配置的模型，开发出校园地理信息系统软件。实践证明，采用这种技术能缩短地理信息系统软件的开发周期，提高软件的可扩展性。
This paper describes Geographical Information System's core technology as map layers, vector maps, and spatial-attribute data recognizing, and gives a further comment on GIS which bases on ActiveX technology. Using object oriented method, a model consist of school map, buildings, floors and rooms is built for school GIS. Based on view and view configuration model, using such GIS platform, a school GIS software is developed. This application shows that using such GIS platform can shorten GIS software developing cycle and improve software extendibility notably.
