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

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
