地理信息技术的发展与应用

地理信息系统是国家信息资源的重要组成部分。地理信息技术经过20多年的飞速发展，已经渗透到社会各个方面，促使人们生产、生活方式发生深刻变化。我国地理信息系统(GIS)技术正在向信息化方向发展，并正在逐步成为面向21世纪的支柱产业一信息产业的重要组成部分。国际GIS技术的发展趋势，主要体现在两个方面，一是综合，二是分化。从空间信息处理的角度看，可将GIS的发展分为空间信息的管理、分析、模拟和调控四个阶段。GIS技术的应用表现在一是面向大型项目，二是面向公众。

DEVELOPMENT AND APPLICATION OF THE TECHNOLOGY OF GEOGRAPHICAL INFORMATION

Technology of geographical information system is an important part in the resources of national information. The technology of geographical information has developed at a high speed over 20 years and infiltrated into every aspects of society, which has also promoted profound changes in production and life style. The technology of geographical information system (GIS) in China is progressing toward into a backbone industry in 21th century an important component of information industry. The development of the international GIS technology mainly appears as two aspects; one is comprehensive and another is differentiation. The development of GIS can be divided into four stages of management, analysis, modeling and adjustment at space information from the processing the space information.
