Project Overview

China’s Central Government decided to develop a national System

• Geospatial is one of “four information foundation databases”

in China’s e-government– Essential in coming years– Needed for Economic growth and Social Development

• A government regulation (2007-17 “tenth-five” development cycle.

. . . Facilitated and lead by the Development and Reform Commission, collaborating among related government organizations

信息库项目建设及运行组织体系

Data Management Challenges

• Collaborative development and maintenance the foundation data • Complexity of integrating spatial information• Diversity of data and service types• Database update is essential for mission critical applications

Major Goals and Contents

• Promote the sharing and exchanging of information in government(Compliant with standards)

• Establish one major datacenter and 11 sub datacenters • Provide the capability of information exchange and sharing services

• Rely on government networking infrastructure• Provide services to the general public. • Support state level integrated decision making• Apply geospatial services to other e-government systems

Major Services

• System Components– metadata sharing service– data sharing service– application services– database system– operating and management system
