Short Introduction of NRSCC
Subdivision of the Ministry of Science and Technology (MOST)
Formulating the national policies and long-term plans for developing remote sensing science and technology, geographic information system and satellite navigational technology
Coordinating amongst different departments in organizing and implementing nation-wide projects in order to promote remote sensing research and applications
Coordinating and develop international cooperation
Acting as China’s contact point responsible for liaison with international organizations.

Data Services in NRSCC Most Departments provide dedicated geographical
information services based on projects Mainly 2 Departments provide operational satellite
data services to public China Remote Sensing Satellite Ground Station Department of Meteorological Satellite (National Satellite
Meteorological Center) Mainly 2 Departments provide airborne remote sensing data
services national wide Department of Document Service Department of Land Resource

Status of Data Services Most Data providers are manual operation to
provide information services case-by-case Operational agencies adopt some formal methods
such as metadata browsing, data ordering and deliver with CD-ROM, Tape or Film
Some of them can provide network services
Example of data service in RSGS

China RSGS
Organization of RSGS Civilian organization supervised by Chinese
Academy of Sciences
Inaugurated and put into into operation from December 1986
Re-organize its structure in July, 2001
Up to now 120 employee including 70 scientists, engineers and technicians

DATA Services (continued)
• Metadata Data Management System is used to provide necessary information to users
• Up to now two browsing systems set up for users world wide
• One is set up about 10 years ago and another one is developed last year by RSGS
• We use M2M methods to transfer different metadata to uniform metadata
• Matadata system is based on oracle data base and make use of ARC SDE to provide geographical service

Future Aspects of Data Services in NRSCC
Promoting the remote sensing data sharing national wide
Establish China Space Information Network to provide one-stop data services for end users
Further connecting and coordinating data sources and providers with other national agencies
Establish network-based services and satellite-based broadcasting services
Providing real-time, near real-time and offline services for different users
