1. CEOS WGISS Technology & Services Subgroup Overview by Wyn Cudlip British National Space Centre/QinetiQ wcudlip@space.qinetiq.com Presentation

2. Technology & Services Subgroup o Organised into Task Teams o To address technical issues associated with the: n acquisition n storage n processing n locating n delivery n of EO data and services o Fosters the exchange of technical information o Promotes the use of Open Standards and the development of interoperable systems

3. T&S Issues o EO-User Perspective: o Locate - Directory Services o Search - Catalogue Services o Retrieve - Data Services o Provider Perspective (in addition to above): o Archive Hardware; Formats; Preservation Strategies o Processing GRID Systems and Tools o Information Exchange – Guideline Documents; Workshops

4. Directory Services

5. o CEOS International Directory Network (IDN) and the o Global Change Master Directory (GCMD) n With 4 co-ordinating notes around the world o Registry describing over 15,000 Datasets o Uses DIF metadata standard n Now compliant with ISO19115 metadata standard o 50,000 hits per month o Specific User Portals can be created. o http://gcmd.nasa.gov/ http://gcmd.nasa.gov/

6. GCMD Search Page

7. JAXA IDN Portal

8. Also, can register services

9. Additional GCMD Services

10. Catalogue Services

11. o WGISS developed the CIP n Catalogue Interoperability Protocol n Based on a profile of the Z39.50 protocol developed by the library community n Allows transfer of search and order parameters and the return of the results o Basis of Interoperable Catalogue System (ICS) n ESA implementation called INFEO n Allows distributed searching of ESA and NASA catalogues n Other Nodes to be added o http://catalogues.eoportal.org http://catalogues.eoportal.org

12. ESA EO Portal

13. Data Services

14. o Working to exploit specifications emerging from the Open Geospatial Consortium (OGC) o In particular: n Web Map Server – for rgb raster data n Web Feature Server – for point and vector data n Web Coverage Server – for low-level satellite data o Allows information layers from distributed on- line servers to be combined

15. Near-Real-Time MODIS Display

16. JAXA/RESTEC Land Condition Map - Geomorphological Land Classification Map - Sudsurface Geological Map - Soil Map - Land Use Map - Satellite Image (Past) - Satellite Image (Recent) - Elevation map - General Map : Postal Code

17. Data Search & View System

18. Archiving

19. Archive Issues o Archive interchange format (CEOS ICF) o Long-term preservation strategy o Archive hardware issues n Disc vs. tape n reliability o Data formats in general n Format Guidelines Document n Browse Guidelines Document o tape-data recovery activities n Baking recommendations n Assistance to Developing Countries

20. Disc versus Tape costs

21. Tape storage trends

22. GRID Computing

23. o Large international investment into the development of GRID concepts and tools o Exploitation of computational GRIDs for the benefit of EO data analysis is under investigation by CEOS WGISS.
