China SIG Project SIG Container Data Resources Computation Resources Grid Portal

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

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

(http://grid.rsgs.ac.cn In Chinese Only)

• Some middleware can also be free-accessed• There are 12 nodes have been installed one kin

d 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, middle

ware 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
