Abstract
Funding conditionBuild a Application-oriented Grid CGDP: China Grid Portal of
Scientific Spatial Data
RSGS,CAS
Funding Condition
• The first funding closed at the end of 2003.
• Research work has been interrupted during almost whole 2004
• New funding started from the last Oct.
2004 2005
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.
