CEOS GRID Proposals roundtable Introduction

• luigi.fusco_at_esa.int
• ESRIN, 6-7 May 2002
• CEOS Workshop on GRID

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

GRID and EO-Applications a proposal for a CEOS
WGISS testbed Luigi Fusco, ESA-ESRIN6 May
2002, Draft 31. Introduction2. European, USA
and other Initiatives related to GRID3. Rational
for a CEOS GRID action4. The Earth Science GRID
vision 5. Summary of ideas for defining a CEOS
GRID prototype (as discussed in various e-mails)
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

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
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)

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 ?

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
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
