  1. Chinese Grid Activities Update Guoqing Li NRSCC/CEODE Present to WGISS-27, Toulouse, France May, 2009

  2. Outlines • Technology under developing • Gird-based Applications

  3. 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

  4. 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

  5. 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

  6. WPS framework based GE service

  7. 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

  8. 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

  9. 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

  10. English Version will be found in Version 2

  11. 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).

  12. 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

  13. Disaster Mitigation Collaboration Platform 1 Wenchuan EO data assistant grid GEO/GCI DM Collaboration Portal 2 ASIAES clearinghouse for disaster Stage 1 CEODE disaster collaboration platform proposed 3

  14. Spatial Information Processing Computing Grid China Coastal observation information system approved 1 Spatial Computing Grid Polar Sea Ice weekly monitoring system approved 2
