China SIG Project  SIG: china spatial information grid A national geo-information grid  Three steps : to study prototype and key technologies : to build test-beds 2006: to integrate grid tech with applications

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)

 SIG Container Free download from SIG site ( 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.

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.

 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)

 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

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

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.

 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)

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
