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.

• WGISS has developed tools, standards and services to assist access to and use of EO data resources available online worldwide.

CEOS Grid Prototyping Project - Main Issues

• POC: Yonsook Enloe (yonsook@harp.gsfc.nasa.gov)• 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.

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).

– 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.
