面向对象技术的矢量图形系统开发及其扩展

Design and application of vectorgraph based on object-oriented technology

GIS在国民经济和社会生活中得到了广泛的应用,已经成为了IT的重要组成部分,而面向对象技术日益取代传统的结构化程序设计方法,是当代软件开发技术的主流。本文阐述了面向对象的系统较结构化的设计软件具有明显的优势,介绍了基于面向对象技术的软件工程思想开发矢量图形系统的整个过程,并结合实例利用Visualc++6.0开发适用于煤矿安全分析可视化研究中瓦斯抽放管理的系统。

GIS is widely used in many fields and it has become an important part of IT. Object-oriented technology increasingly replaces the traditional procedural programming techniques and it is the up-to-date programming techniques today. The software engineer ideology based on Object-Oriented technology and the programming processes are presented. Then with Visual C++6.0, an application in the Colliery Security—Gas Management is given from the point of the view mentioned before.
