摘要
地理信息系统(GIS)是一种用于储存、管理和分析空间信息的强有力的工具,随着其应用的日趋广泛和自身的不断完善,目前GIS的发展出现了新的特点:时空4 维GIS、与CAD 以及RS和GPS集成、与专家系统结合、与虚拟环境技术结合、开放式GIS等。本文对此进行了综述,并从GIS的定义、对空间信息的存储与管理方式、数据来源等方面对地理信息系统的概念、原理及主要应用作了简要介绍。
The Geographic Information Systems (GIS) is a tool designed to use computer system to efficiently capture, store, update, manipulate, analyze and display all forms of geographically referenced information. During about 30 years of its developing process, its function becomes stronger and stronger. As not only a powerful technology but also a kind of spatial information science, GIS has been widely used in many fields, and its development appears some new features: 4D GIS; convergence of GIS and CAD; 3S(GIS, GPS and RS) integration; combined with Expert System; Virtual GIS; OpenGL GIS. All above mentioned developing trends of GIS were reviewed in this paper, and the concept, principle, and mainly uses of GIS were also introduced concisely.
