  1. China Grid Activity on SIG Presented by Guoqing Li At WGISS-21, Budapest 8 May, 2006

  2. Content • China SIG Project • SIG Container • Data Resources • Computation Resources • Grid Portal

  3. China SIG Project • SIG: china spatial information grid • A national geo-information grid • Three steps • 2002-2003: to study prototype and key technologies • 2004-2005: to build test-beds • 2006: to integrate grid tech with applications

  4. SIG Container • SIG Container: uniform grid environment to every SIG resource node. • Two type distribution versions • Lite version. (v2.0) • Meta version. (v2.0) • Meta= Lite + (registration center)

  5. SIG Container • Free download from SIG site (http://grid.rsgs.ac.cn In Chinese Only) • Some middleware can also be free-accessed • There are 12 nodes have been installed one kind of Containner. • Dr. Huang will give detail explanation about it.

  6. Data Resources • There are 12 data centers have been involved SIG. • There are two national spatial data distribution systems can be accessed from this grid portal : • MODIS data distribution system. • ENVI-SAT data distribution system.

  7. Fast deploy technology • Models and tools • Within days (include interface designing, middleware developing and data-center deploying) • MODIS sets: 2 days • ENVI-SAT sets: 5 days (because it used a third part grid middleware)

  8. http://ds.rsgs.ac.cn http://www.nfiieos.cn/rili/viewdate.asp

  9. All data resources • Uniform query interface and parameters • Uniform result page • Two level actions • Portal level • View list • View simple metadata • Data center level • View original metadata and quick look image • View storied data image (via WMS) • Download data directly

  10. Two type data discover : • On-line: a broker • Off-line: based on a cached metadata catalogue • They have same interfaces and portal faces

  11. Computation Resources • There are three software packages have been integrated SIG • PIPS. • Developed by RSGS,CAS • Based on HPC (16 CPUs Cluster ), can bring fast on-demand data processes. • Titan. • Developed by Titan Co. Ltd. • Based on workstation, can bring on-demand data processed. • ISPRS-MODIS • Developed by IRPRS, CAS • Based on Condor Cluster ( 5 workstations ), can bring on-demand MODIS data processing.

  12. All computation services • Can input data from grid service • Can output data can be accessed with service interface • Can be chained as workflow • Computation Job • Can be submitted on-line • Can be run at once • Can be monitored whenever you want to check , with the job number (Job Order)

  13. Grid Portal • One-stop grid portal to user • What they can do from here? • Discover geo-data as they want • Process geo-data fast and easily • Monitor their work • Manage grid resource (all service/job/node etc.) • There are Chinese and English Versions

  14. DEMO • Click to see (http://grid.rsgs.ac.cn Chinese Version Enter) (http://159.226.224.52:6140/Grid/application/index_en.jsp English Version Enter )

  15. Thank you!
