摘要

国家空间数据基础设施（ＮａｔｉｏｎａｌＳｐａｔｉａｌＤａｔａＩｎｆｒａｓｔｒｕｃｔｕｒｅ，简称ＮＳＤＩ）是“数字地球”的基础。要发展中国数字地球及其应用，就必须加大ＮＳＤＩ的建设力度。文中主要从（地球）空间数据框架、空间数据标准、空间数据交换网络和空间数据协调管理机构４个方面，介绍了中国ＮＳＤＩ的有关进展，分析了其中存在的一些问题，讨论了发展方向

Abstract

The National Spatial Data Infrastructure （NSDI） is the basis of digital earth. It is therefore very essential to develop NSDI in order to implement the vision of a Digital earth. This paper reviews the recent progr ess and future activities of NSDI in China

including the national geodetic fram ework

multi scale geo spatial databases

national efforts on geo spatial dat a standardization

establishment of national geo spatial clearinghouse network

coordinati on of national efforts in acquiring

processing and utilizing geo spatial dada.
