1 CEOS WGISS & Subgroup Meeting Beijing, September, CEOS WGISS Technology & Services Subgroup Overview Wyn Cudlip British National Space Centre/QinetiQ Presentation to WGISS Workshop Beijing, September, 2004

2 CEOS WGISS & Subgroup Meeting Beijing, September, 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 CEOS WGISS & Subgroup Meeting Beijing, September, 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 CEOS WGISS & Subgroup Meeting Beijing, September, Directory Services

5 CEOS WGISS & Subgroup Meeting Beijing, September, Directory Services 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

10 CEOS WGISS & Subgroup Meeting Beijing, September, Catalogue Services

11 CEOS WGISS & Subgroup Meeting Beijing, September, Catalogue Services 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

12 CEOS WGISS & Subgroup Meeting Beijing, September, ESA EO Portal

13 CEOS WGISS & Subgroup Meeting Beijing, September, Data Services

14 CEOS WGISS & Subgroup Meeting Beijing, September, Data Services 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
