数字地球与地球信息科学

本文从全球信息基础设施(GII)、地球空间数据基础设施(CSDI)、地球空间数据网络集成、科学计算可视化出发,阐述了数字地球面向社会大众与面向地球科学研究的两种不同的功能性构造体系的建立,并结合对于地球信息科学的理论、方法和技术的阐述,分析了数字地球与地球信息科学两者之间的关系。分析结果表明,如果将数字地球构造体系的建立与地球信息科学的研究结合起来,必将极大地推动2l世纪地球科学的发展。

Digital Earth and Geo-information Science

Proceeded from the Global Information Infrastructure (GII), Global Spatial Data Infrastructure (GSDI) , Network Integration of Geo-spatial Data and Visualization of Scientific Computing, this paper expounded the building of the two kinds of different functional-construction-systems of Digital Earth, which are geared to the needs of the social public and the research of Geoscience; and also analyzed the relationship between Digital Earth and Geo-information Science in conjunction with the expounding of the theory, method and technology of Geo-information Science. The analytical result proved that the development of Geoscience in the 21st century would certainly be pushed forward through making the conjunction between the building of the construction system of Digital Earth and the research of Geo-information Science.
