1 WGISS 1 Report and Recommendations from the Technology & Services Subgroup Liu Dingsheng CEOS/WGISS-26, Boulder, CO., USA September 22~26, 2007

2 WGISS-26, Boulder Colorado, USA Sep , Topics Structure, Activities and Changes Highlights and recommendations from IG’s Technical issues from the reports of all IG’s Recommendations from Technical point of view

3 WGISS-26, Boulder Colorado, USA Sep , Structure, Activities and Changes Current Structure  Subgroup Leaders Chair: Liu Dingsheng, NRSCC Vice Chair: Nataliia Kussul, NSAU  Interest Groups International Directory Network (IDN) – Lola Olsen, NASA Interoperable Catalog System (ICS) – Jolyon Martin, ESA Grid – Li Guoqing, RSGS/NRSCC Sensor Web - Terence Van Zyl, CSIR Web Services – Lyndon Oleson, USGS Data Services – Paul Kopp

4 WGISS-26, Boulder Colorado, USA Sep , Structure, Activities and Changes Activities during WGISS-26  Individual Meetings Grid International Directory Network (IDN) Web Services  Joint Meeting Sensor Web - Terence Van Zyl, CSIR  Under Consideration and Discussion Data Services  No Activity Interoperable Catalog System (ICS)

5 WGISS-26, Boulder Colorado, USA Sep , Structure, Activities and Changes Changes  Subgroup Level According to the WGISS Terms of Reference, Dingsheng shall finish his duty at the end of WGISS-26 Nataliia Kussul will be the chair started next WGISS meeting Call for volunteer as new vice chair to take his/her duty for two years and than chair for another two years Waiting for the responses from WGISS society

6 WGISS-26, Boulder Colorado, USA Sep , Structure, Activities and Changes Changes  Interest Group level Grid: Dr. Shelestov Andrii (Ukraine/NASU) will replace Guoqing Li as the leader ICS Jolyon Martin think that the most progress for interoperable catalogues is done through OGC and asked WGISS to consider closing ICS formally

7 WGISS-26, Boulder Colorado, USA Sep , Highlights and recommendations from IG’s Grid – Highlight  The Wide Area Grid (WAG) was going forward and the draft architecture document has been delivered to reviewer  Headed by NASU, Ukraine, CAT-1 Project on Flood Monitoring via Grid obtained many good results  China Special Information Grid (SIG) successfully applied to provide emergent metadata assistance during Wenchuan Earthquake based on international EO data support  New Project “Grid Technologies for Multi-Source Data Integration” started from 2008

8 WGISS-26, Boulder Colorado, USA Sep , Highlights and recommendations from IG’s Grid – Recommendations  WAG should be one of the key concepts of WGISS technology To promote it to be WGISS key technical solution to support constellations and sensor web etc.  Grid can be used as technical basement for EO data democracy  Grid research could focus on the on-demand processing capability

9 WGISS-26, Boulder Colorado, USA Sep , Highlights and recommendations from IG’s Grid – Recommendations  Future Project: CEOS Huge Disaster EO Data Aid Action (HDEDAA) First Stage: as a WGISS project with one years period Next Stage: as a GEO action contributed by CEOS Possibilities  WGISS own the technologies, experiences and data resources Main Factors:  How to organize CEOS agencies to give the data assistance?  How to establish an efficient mechanism to take fast response for the huge disaster

10 WGISS-26, Boulder Colorado, USA Sep , Highlights and recommendations from IG’s Grid – Potential contribution to GEOSS NASU Flood Monitoring testbed - Relate to Disaster and Water, SBA CNES international WAG Project - Relate to ADC or AIP ? NRSCC Disaster EO Data Aid Action - Relate to Disaster, SBA WGISS Grid experts could be deeply involved in GEOSS ADC work - Relate to ADC

11 WGISS-26, Boulder Colorado, USA Sep , Highlights and recommendations from IG’s IDN – Highlights  SERF Population keep growth linearly

12 WGISS-26, Boulder Colorado, USA Sep , Highlights and recommendations from IG’s IDN – Highlights  Both users and content statistics were presented and showed continued and growing interest in the IDN  MD 9.8 Released June 2008  GCMD Team has produced detailed Responses to all the recommendations of the Science User Working group (SUWG) with GCMD Strategic Plan FY and Final Response Document  The Climate Diagnostics portal was presented and appeared to be "well-received“ to support GCOS (CL )  Contributions to the Land Surface Imaging portal were briefly reported

13 WGISS-26, Boulder Colorado, USA Sep , Highlights and recommendations from IG’s IDN – Recommendations  Continue to provide high-quality Earth science metadata, and active contributors to keyword development, standards definitions and the semantic web  Work towards greater inclusion of NASA datasets  Extend metadata holdings to include popular datasets such as climate change indicators  Continue to promote the GCMD “Brand” through papers, posters etc  Encourage the creation of provider-maintained metadata, exploiting DocBuilder and web interface enhancements  Continue to develop Strategic Plan

14 WGISS-26, Boulder Colorado, USA Sep , Highlights and recommendations from IG’s Web Services – Highlight  Established after WGISS-25, The Web Services Interest Group held its first meeting at WGISS-26, detailed the purpose of Web Services Interest Group  Several presentations were made regarding strategies, plans and lessons-learned with using OGC and other Web Services  Layout a good guidance to a Web services-based SOA through USGS/EROS activities related to the re- architecting and redesigning Earth Explorer and GloVis, such approach could create a new baseline for future capabilities  Interest Group members also discussed ideas for continuing to engage in technical exchanges via telecons and other forums throughout the coming year

15 WGISS-26, Boulder Colorado, USA Sep , Highlights and recommendations from IG’s Web Services – Summary and Recommendations  Continue with plans to evolve EE and GloVis into SOA, Web services architecture  Collaborate with CEOS and US GEO interoperability efforts  Initiate investigations into performance mitigation approaches and solutions  Pursue prototypes to more deeply explore Web Service implementation and performance issues and feasibility  Web Services are a part of the future

16 WGISS-26, Boulder Colorado, USA Sep , Highlights and recommendations from IG’s Data Services  Under consideration and discussed individuals  It should be service-oriented and concentrated on how to provide long term or sustainable data services  It may an important potential services to provide data assistance to WGISS activities  Call for CEOS agencies participations and ideas to layout its objects, forms and activities

17 WGISS-26, Boulder Colorado, USA Sep , Technical issues and questions Based on the requirements from GEO, Most activities are mixed technical issues and projects recently What should be the object of IG’s?  Technical-oriented? Projected-oriented? What is the core technologies of GEOSS and how to make our contribution to GEO ?  Registry  Clearinghouse  Portal  Interoperability  …… WGISS owned many technologies but how to make it become whole set to support a dedicated system or application

18 WGISS-26, Boulder Colorado, USA Sep , Recommendations from Technical point of view How to identify WGISS IGs ?  Project-Oriented technology IG Promote the applications of new technologies in the project Concentrated on the solutions of technical problems  Technology-Driven project IG Promote the applications of new technologies in the project Concentrated on the application of mixed technologies

19 WGISS-26, Boulder Colorado, USA Sep , Recommendations from Technical point of view WGISS Structures and Meeting forms  Long term and short term Long term – Technology-oriented, Services-oriented Short term – Project-oriented  Themes-oriented meeting – mixed technical issues and projects together Such as Sensor Web Day Next may Web services Day (Half Day) Data Services Day ……
