10The need from the user view point
- Today
- gt75 of the EO data users, access data from
- more than 1 instrument/satellite
- close to 90 require other auxiliary data (e.g.
met. or ground truth data) to
process/correct the satellite data - Today a lot of
- missions, instruments, data, tools, information
- off-the shelf technology
exist - However
- no coherent access technically
- no common international policy for data access
and use - Everybody only knows parts Users know even
smaller parts - Services providers spend up to 40 of their time
getting access to data rather than providing the
services

11The need to respond to the technological evolution
Phase 1 (1980-1990) ESA to develop Europ.
Technology for EO Data access Earthnet Programme
Phase 2 (1990-2002) Large nationally funded
infrastructure developments ESA to enable
support such national developments in the context
of its and other individual missions
- Phase 3 (2003-2010)
- Develop global EO based service (independent of
the space mission) - Convert and tune overcapacity to service needs
- Reach sustainability of services, benefits
budgets (existing operations to become more
efficient) - Benefit from now available off-the shelf
technology (less development) - Networking technologically and programmatically
incl SMEs, - contingency agreements among operators
- International EO standards
- Internationally agreed EO policy
12Oxygen Objectives
- Oxygen is a concept aimed at
- Facilitating access to EO data from ESA and
other missions - Increasing sustainability of EO data
provisionwidening the range of offered data
sources - Making the operations of EO missions more
efficient - Oxygen has started more than 1 year ago and is
ongoing - to enlarge the benefits of EO (even in absence
of GMES) - Oxygen is probably a pre-requisite for a
successful EO GMES component -
13Main conclusion on existing Systems
-
- User Services
- Multiple EO Portals (11), Orders desk(11),
Catalogues (12), Interoperatability Protocols
(19) - Many servers for online data access .. in
different locations .. with different type of
services .. providing partial data sub-sets. - Difficult for a user to find the right path to
the required data - Mission Planning
- Many single Mission Planning tool. No tools
supporting cross-missions acquisition planning. - ? Users and Mission Planners do not have
visibility of acquisition possibility
across-missions - Mission/Sensors Performance Monitoring Quality
Control - Q/C tools are mainly instrument specific
- No standard indicator of sensor or product
quality - ? Complex environment limited to experts
14ESA GS layout today
15Functions / Facilities Overview
- There are many facilities
- All with different functions, interfaces and
agreements or contracts with ESA - The number of facilities is increasing (more and
more public user entities assume a role as
ground segment facility) - Discussion in cooperation and evolution is
ongoing at different levels with many of the
facilities

18Ground Segment elements
- Facilities harmonization
- Detailed definition of open architecture
- identification of generic-common elements,
specific mission elements and define standard
interfaces - Evolution of existing system rather than new
developments - Evolution of the common elements to integrate new
missions

21Oxygen Work Plan
22Oxygen Short-term Implementation
- Analysis of Existing
- Technically
- Make existing more easily accessible (web
portal, on-line archiving, networking, shared
tools and services) - Tune new developments towardsa generic ground
segment approach - Policy and price wise
- Harmonize data access conditions
23Implementation Plan (2003 2005)
- EO Web Portal for awareness of missions, user
services, products, information and service
providers - Online Data Access provision of online products
and improve online exchange of data - Service Support Environment for easing provision
of Services by Service Providers - Archive rationalization Ensure data Archives
integrity and access for ESA and national
missions support - Harmonization of ground segments for current and
future ESA missions - Archive and NRT Facilities Architecture
- User Services and Order Handling
24Implementation Plan (2003 2005)
- Policy and Programmatic
- Enlargement of data sources through 3rd parties
cooperation - Data policy evolution adjust ERS and Envisat
data policy to GMES service needs and to internal
cooperation requirements - Ground Segment Task Force to define goals for
European EO Infrastructure - Integrating upcoming EO National projects in
Europe - Feasibility assessment at political, technical
and programmatic level (Terrasar-X, Radarsat-2,
Cosmo, Pleijades) - Pilot activities for interoperability between
catalogues, order and online distribution systems
(standards in SOAP/XML)
25Oxygen Phase 2
- Objectives
- cost-efficient Ground Segment infrastructure for
future European and member states missions - Prepare the EO Data Acess Component in a GMES
proposal along with the mission and service
proposals to assure coherent, planable,
sustainable EO input to GMES - Establish the (mission independent) single ground
segment infrastructure and operations concepts
for the new Earth Explorer missions (Adm, SMOS,
2nd series of Core missions etc) - Respond to user needs for access to maximum
number of mission data - Implementation
- See GMES preparatory phase proposal, the GSE
infrastructure and Task Force recommendations - Design and Architecture
- Interface Definition
- Development Contracts
- (Dedicated Programme Line rather than just using
mission dependant funding)
26Oxygen Technical Projects
27Oxygen eoPortal
- http//www.eoportal.org
- The new eoPortal was created and opened in
November 2003 to provide access to and promote
European EO activities. - provides access to web resources from ESA and
other institutes - re-uses all components of the INFEO initiative
(JRC/CEO) and adds new features - comprised of sub-sites to provide access to
various data types - directory of resources
- calendar
- maps
- catalogues
- services
directory
maps
catalogues
28eoPortal catalogues
- http//catalogues.eoportal.org
- Access to distributed catalogues,
- new client for catalogue interoperability based
on the EOLI look and feel - Provides two levels of search, collection search
and product search - Allows access to collections from distributed
catalogues - As INFEO follow-up currently ESA (gateway to
MUIS), DLR (gateway to DIMS), NASA (gateway to
EOSDIS) - new standards (SOAP/XML with ISO compatible data
model) shared with MASS Vito, Envisat, CNES-SPOT
for inter-access towards DALI catalogue
29Simple interoperable catalogues
- Principles
- Based in XML/SOAP
- Content of information minimized according to
user needs - On-going specifications
- Catalogue access (available, pilot activities
on-going) - Order Handling (definition being finalized with
CNES, DLR) - Systems supporting the above protocols
- MUIS / EOLI ESA users services front-end
- MASS / SSE non-ESA providers integration platform
30ADAR Logical model (OASI-based)
31MMFI Schedule
- Implementation of the Facilities Open
Multi-mission Infrastructure and evolution of
existing missions - ITT to issued within May 2004 (completed within
fall 2005) - Migration plan toward ADAR architecture
- Envisat evolution
- ftp function (June 2004),
- Archives evolution (November 2004-2005),
- Completion of ERS and TPM integration by mid 2005
- Completion of Archive management and
rationalization (HARM) activities within 2004,
including European archive format implementation
32Online Data Access Principles
- On-line Archive (MMFI - ADAR) Mass Storage Tape
Libraries or on disk - User data request via Internet bypassing manual
validation (order or subscription) - Product retrieval via Internet
- High speed Internet backbone (GEANT/NREN) for
academic users - Commercial ISP augmented with load-balancing and
re-routing COTS - Product distribution via Internet over Satellite
- Distribution Servers providing on-request and
subscription data - Electronic data distribution between GS Centers
using High Speed Intranet (based on GEANT/NREN) - Security Principles
- Detect and avoid unauthorized use of EO data
- Protection from malicious intrusion

39Conclusion
- GMES is a user programme not a technology
demonstration - The users exist they already have tools and
systems - The EO ground segment exists with many players,
contributors, systems. - EO is just one element contributing to GMES
- Risk management is just one element of GMES
- The GMES success will be measured on whether it
delivers not on the technology, the architecture
or the mechanism used - The challenge is to make this work together
