1. 6-7 May 2002 CEOS GRID Workshop 1 “CEOS GRID Proposals” roundtable: Introduction luigi.fusco@esa.int ESRIN, 6-7 May 2002 CEOS Workshop on GRID

2. 6-7 May 2002 CEOS GRID Workshop 2 Considerations for CEOS “involvement” in GRID “gridding” of EO emerging technologies and services –Interoperability –EO data format handling –Web-mapping –Archive management Demonstrate GRID applications –International project dimension –collaborative environment –relation with IGOS, WGISS Test Facilities … Support “CEOS standardisation” approach to metadata and data access

3. 6-7 May 2002 CEOS GRID Workshop 3 GRID and EO-Applications: a proposal for a CEOS WGISS testbed Luigi Fusco, ESA-ESRIN 6 May 2002, Draft 3 1. Introduction 2. European, USA and other Initiatives related to GRID 3. Rational for a CEOS GRID action 4. The Earth Science GRID vision 5. Summary of ideas for defining a CEOS GRID prototype (as discussed in various e-mails)

4. 6-7 May 2002 CEOS GRID Workshop 4 Rational for a CEOS GRID action possible goals –immediate access to datasets acquired from various stations around the world –integration/fusion of multiple distributed data sources –extraction of knowledge and information –demonstration of services for environmental monitoring and natural resource management Immediate benefit –High Speed Networks deployment –Open user interface to Archives for Data Access –Utilisation of common GRID standards

5. 6-7 May 2002 CEOS GRID Workshop 5 Basic GRID Services: Security, Resource location, etc. Self-Standing Software Building Blocks High-Level GRID Services: Workflow Management Portal User Access Application Development Environment (EO) Application Repository Network: physical infrastructure, i.e. high-bandwidth fibre optics, computers, archiving and processing equipment etc. GRID Basic System Layers Earth Observation Application Layers Earth Science GRID vision

6. 6-7 May 2002 CEOS GRID Workshop 6 Suggestions for CEOS GRID projects (1) Follow WGISS Test Facilities approach –Start with one mission: ALOS, Landsat 7, … –Based on Web Mapping tools –Consider regional stations role –Meet specific science groups requriements: e.g. Envisat AO –Demonstrate real time data access –Ocean Test Facility

7. 6-7 May 2002 CEOS GRID Workshop 7 Suggestions for CEOS GRID projects (2) Support “operational EO services” –International Charter for Disaster Management –Other NGOs and UN conventions (e.g. UNOPS, WHC) –Generation of high level products (e.g. high res land use) GODAE “common”: GHRSST – PP –access to global and regional AVHRR, AATSR, MODIS, MSG, AMSR… –(consider full involvement of OTF)

8. 6-7 May 2002 CEOS GRID Workshop 8 GODAE “Common”: GHRSST-PP infrastructure

9. 6-7 May 2002 CEOS GRID Workshop 9 GHRSST-PP DDS system

10. 6-7 May 2002 CEOS GRID Workshop 10 GODAE “Common”: personal considerations Technologies –UIS and Metadata Interoperability –Data Access: High Speed Research Networks –GRID Processing –web-mapping portal Project risks ? Participating members ? Funding status ? CEOS – IGOS approval ?

11. 6-7 May 2002 CEOS GRID Workshop 11 GHRSST-PP components: DDD/SDI DDD: Dynamic Distributed Database –Interface various external data sources –Coordinate access and exchange of SST data –Coordinate access and dissemination of GHRSST-PP products –Multiple data acq/proc/arch facilities located at GDAC, DAAC, SAF, … SDI: Satellite Data Integration –Software tools that access and merge internationally distributed SST datasets to create GHRSST-PP products –use of several standard data formats and allow translation across formats

12. 6-7 May 2002 CEOS GRID Workshop 12 GHRSST-PP components: UIS/DDS UIS: User Support Facility –Contains general information, project contacts, product descriptions, metadata repository –Based on OTF DDS: Diagnostic Data Set –Contains HR Satellite data, other satellite data and insitu measurements –provides a means to validate GHRSST-PP products –Distributed and specialised (type of data, geographic areas) quality analysis facilities at various sites –Direct Science user involvement
