RSGS,CAS Abstract Funding condition Build a Application-oriented Grid CGDP: China Grid Portal of Scientific Spatial Data

RSGS,CAS Funding Condition The first funding closed at the end of Research work has been interrupted during almost whole 2004 New funding started from the last Oct

RSGS,CAS Build a Application-oriented Grid Because –Grid have been accepted as important information utilization and serving technology. –Grid research works have been taken widely in the past two years. –Many grid tools and grid demo systems have been finished. => Feasibility

RSGS,CAS But –It is difficult to configure a original data source to be grid services. –It is also difficult to add new spatial processing software to be gird-useful services. – It is still not easy to mine right data form grid data resources. –Even to build a Grid environment is a very professional operation. => Problem in use

RSGS,CAS So we will do: –Feasibility -> Usability. –Build a Application-oriented Grid Environment. –Grid container In SIG, will use uniform grid container as basic middleware and protocols. –Grid Gateway Bring in-LAN resource to be a node of Grid in form of some services.
