Chinese Grid Activities Update Guoqing Li NRSCC/CEODE Present to WGISS-27, Toulouse, France May, 2009
Outlines • Technology under developing • Gird-based Applications
Technology under developing • Grid Entity (GE) A suit of local middle ware and tools to deploy, manage, monitor providers’ resources in form of services. • Engineering level • Grid Entity is not the basic grid component • Grid Entity is used for the assembling of grid resources (web-services) within one institute. • Grid Entity is implemented with the form of WPS container and toolkits
There are three GEs in SIG • P-N:Processing Grid Entity Node • D-N:Data service Grid Entity Node • M-N:Mapping Grid Entity Node
For developer, they can use GE framework to • quickly package their classes (C++, JAVA) • simply assemble other web-service into grid system • easily manage (registry and publish ) all their web-services on grid level • fully support the WCS, WFS and WPS compatible interface
Grid-Based Applications • Applications in three areas: • Global Change Data Portal • Disaster Mitigation Collaboration Platform • Computing Grid for Spatial Information Processing • All the above projects will be constructed with GE
Global Change Data Portal 1 China GC satellite data portal V1.0 2 GC Data Portal (China) Kicked-off GC Data Portal GC Data Portal (APN) - GC-APWG approved 3 ABCC data collaboration platform 4 proposed 5 Sino-Europe Dragon Data Sharing Portal approved
China GC satellite data portal (V1.0) • Data collection • VISSR: FY-2C,FY-2D • MVIRS:FY-1D • MODIS:Terra, Aqua • AVHRR: NOAA 16/17/18 • Scan range: China and East Asia • Archived data level: L1B • Daily data update (average) • 20GB
English Version will be found in Version 2
The next version of China GC satellite data portal (V2.0) is planned to be published at the end of September, 2009. • Add more satellite data types, as well as airborne data . • Extend scan range to Asia and global level, through inter-grid connection with other web-service based data resources. • Use simple cross-grid security control. • Provide on-demand data, include sub-image, mosaic, format and projection transferring. • Provide on-demand processing production, beginning with about 10 types of MODIS high level information productions (based on HPC).
GC Data Portal (China): Global Change Geo-science Data Cooperation Platform • Four scientific data types: • Imagery data (space-borne and air-borne data) • In-situ data • Model data • Modeling simulation data • Connecting 10 institutes and universities
