Committee on Earth Observation Satellites
(CEOS)
• Committee on Earth Observation Satellites (CEOS) consists of world's
government agencies responsible for civil Earth observation (EO)
satellite programs, along with agencies that receive and process data
acquired remotely from space.
• Main goal of CEOS is to ensure that critical scientific questions related
to Earth observation and global change are covered, and that satellite
missions do not unnecessarily overlap each other.
• CEOS specific objectives:
– Cooperate in mission planning and in development of compatible data
products, services, applications, and policies.
– Provide focal point for international coordination of space-related EO
activities.
– Exchange policy and technical information to encourage complementarity
and compatibility of observation and data exchange systems.

CEOS Working Group on Information
Systems and Services (WGISS)
•
•
WGISS Goal: To stimulate and coordinate the development of member
agency systems and services which manage and supply the data and
information from participating agency Earth observation (EO) missions.
WGISS specific objectives:
– Assist EO data provider agencies to maximize the usefulness, easy access and
application of EO data they gather and provide to diverse users worldwide.
– Address needs of EO data and information users by aiding development of
services that provide simpler and wider access to EO resources.
– Emphasis is on using demonstration projects involving user groups to identify
and solve critical interoperability issues associated with achievement of global
services.

CEOS Grid Prototyping Project Main Issues
• POC: Yonsook Enloe ([email protected])
• CEOS Grid issues:
– Six application projects with widely differing application areas.
– Many issues are common to all six projects.
– Project team is working together to gain insight into these common
problems.
• Issue 1: Lack of Grid software how-to install and use documents:
– Team is producing how-to documentation: Grid Cookbook pages.
– 1st cookbook page: How to install and configure Globus 2.2.
– 2nd cookbook page: How to install and configure GridFTP with multiple
hosts and multiple clients.
– 3rd cookbook page (in progress): How to put simple applications on the
Grid.
• Issue 2: Lack of Grid expertise by participants:
– Grid Experts (IPG, . . .) are acting as consultants on various specialty
topics.
– Formed Tech Team to help each other and help later participants.
April 2003

Main Issues, Cont’d.
• Issue 3: Most agencies have firewalls. How to deal with these and how
to configure to allow access?
– Network Team is gathering requirements for firewalls and is drafting a
"CEOS Grid Firewall Best Practices" document.
– Technical POCs interested in this issue will review document with their
firewall administrators and will iterate on the document.
• Issue 4: Grid Monitoring:
– Network bandwidth performance testing and checkout of network routing
is being performed between testbed nodes.
– Several Grid Monitoring tools (Map Center, Ganglia, NWS) are being
studied and tried out.
– Map Center monitoring tool can monitor host machine ports and perform
process level monitoring.
– CEOS Grid application sites are linking to this tool to try it out (work in
progress).
April 2003
15
Main Issues, Cont’d.
•
Issue 5: Certificate Authority (CA): How should host and user certificates be
implemented in an international multi-agency consortium?
– Small tiger team formed to study issue with Grid expert.
– Procedure for CA has been drafted and is being reviewed.
– Planning to use certificates from multiple sources (work in progress).
•
Issue 6: Catalog Issues: Because EO data have huge volumes from many
sources, need a product catalog that is searchable and scalable. What kinds of
catalog components are available on the Grid and do these components have
the necessary capabilities for CEOS catalogs?
– Grid experts on SDSC SRB/MCAT and Globus MCS invited to give presentations
to entire team.
– Catalog Tiger team formed (small team to study and analyze catalog issues and
report back to the main team) (work in progress).
•
Issue 7: Putting EO applications on the Grid:
– Small tiger team formed to study this issue and prototype at least one approach.
– Prototyping OGC Web Map Server (WMS) and Web Coverage Server (WCS) on
the Grid.
– Will generate Cookbook page on putting WMS and WCS on the Grid.
