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,结合环境信息的特点,使用面向对象的方法,抽象出环境管理的污染源、水、气、声功能区等通用概念,基于视图与视图配置的模型,开发出环境地理信息系统软件。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。
The author categorizes Geographical Information System's(GIS) core technology as map layers,vector maps,and spatial-attribute data recognizing and gives a further comment on ActiveX technology based GIS.Using object oriented method,a model consist of pollution source,functional district of water environment protection,air and noise is built for environment GIS.Embracing this GIS platform,an environment GIS software is developed upon view and view configuration model.This application proves that this GIS platform is able to considerably shorten GIS software development cycle and improve its extendibility.
