Task Team Activities
Independent Research and Activity within agency• Interested research works are still running
•NRSCC, CNES, ESA, NASU etc.• Funded projects are less reported successfully won d
uring the past half year•China
– Is just preparing to apply the funds from the next Five Years S&T Plan
•Ukraine– Got a next task: water resources ecological
management, with the platform of GEMLCA (Grid like platform)
•Other Agencies– Status unknown
NRSCC/RSGSESA
CNESNASU
SAS (Slovak)RAN (Russia)
Dragon Project
INTAS-CNES-NSAU project
ESA Category-1
Dragon Project: • Target: to merge ESA Grid and SIG; to support the data
delivery platform for other Dragon projects• Status: Possible beginning from the stage II (2008)• By Luigi and Guoqing
ESA Category-1 Project• Target: Wide Area Grid Testbed for Flood Monitoring using
Spaceborne SAR and Optical Data• Status: under preparation• By Nataliya
INTAS-CNES-NSAU Project
• Target: Data Fusion Grid Infrastructure• Status: Good result of first stage evaluation
• By Nataliya and Paul
Technical Trends Focused
Collaboration among Girds is important and urgently• Less Problem on building Independent Grid System • As the support technology for using Grid in some Inter
national Cooperation Projects• Response to GEO 2007-2009 (Topic 11, Architecture )• New technology trend appeared
Conceptions much discussed in such field.• WAG (Wide Area Grid)• Inter-Grid

Contribution to GEO
Some principles to understand the role of Grid in GEO task• Service-based technologies are the main
basement of spatial information system. • Gird is one of technologies to develop services
and manage services. • Grid can bring merging technologies for different
service-based information components and systems.
• Inter-Grid will be the suit tools to joint many independent grid-based spatial systems for one multidisciplinary application.
What does GEO need?
The success of GEOSS will depend on data and information providers accepting and implementing a set of interoperability arrangements, including technical specifications for collecting, processing, storing, and disseminating shared data, metadata and products. GEOSS interoperability will be based on non-proprietary standards, with preference given to formal international standards. Interoperability will be focused on interfaces, defining only how system components interface with each other and thereby minimizing any impact on affected systems other than where such systems have interfaces to the shared architecture.
---GEOSS 10-Year Implementation Plan, Section 5.3
The new, grouped task would address the following objectives:• Develop and promote practical implementations of the GEOSS a
rchitecture in relation to the Social Benefit Areas, thus enhancing GEOSS' visibility of and demonstrating its benefits. Emphasize the “Global interoperability” concept and consider in detail how various existing interoperability projects (e.g., GMES, INSPIRE) could be part of GEOSS.
• Define and develop the interoperability test-beds for specific Social Benefit Areas and demonstrate and evaluate the results with end-users. Continue to develop the Clearinghouse and Web Portal, and focus on practical applications for specific Social Benefit Areas.
• Consider how recent information technologies such like as Grid computing, SensorML, Ontology, Semantic Web, Web2.0 should be taken into account.
New Task listed:• AR-07-P1: Virtual Constellation
• AR-07-P2: Linking Infrastructures
• AR-07-P3: Interactive Data Access and Analysis System
As a result•Grid TT should response the task of research the new
information architecture.??
•Grid TT should work with other GEO task.– Grid can afford the necessary and professional
support elements for the platform.– Grid can be used to build multi-source data service
system.– Grid can be used to merge distributed processing
resource to support the on-demand data production.
