China Grid Research Update Li Guoqing , RSGS , CAS, China WGISS 19, Cordoba 31 August 2014
Abstract • Funding condition • Build a Application-oriented Grid • CGDP: China Grid Portal of Scientific Spatial Data
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
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
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
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.
