CEOS SEO Functions


The CEOS
Systems Engineering Office (SEO)
was established
in April 2007 (sponsored by NASA) to facilitate the
development of CEOS global space constellation plans.

We have supported CEOS for 2.5 years now !


The SEO
technical function
includes: requirements definition,
gap analyses, special projects, and implementation
architecture development.


The SEO
management function
includes: fostering
communication among CEOS partners by coordinating and
participating in CEOS meetings, developing web
-
based
management tools, and developing visualization products for
educating the global EO community about CEOS.

2009 Accomplishments


Designed an online global
systems database
of CEOS assets to provide
knowledge of CEOS agency contributions to GEO societal benefit areas, to
support CEOS Constellations, and to support gap analyses and strategic
planning. Worked closely with ESA to coordinate data updates for the
CEOS MIM database.


Improved CEOS agency communications by developing: a new CEOS
website (
www.ceos.org
), an action tracking tool, updated mailing lists and
CEOS and Constellation videos, posters and brochures.


Supported several special projects including: an Atmospheric Composition
gap analysis study with Rutherford Appleton Lab (RAL), and a Climate pilot
project focused on climate model uncertainty for decision
-
making.


Supported the planning, conduct and reporting of several Constellation
and Working Group meetings and currently working with CEOS to develop
a booth for GEO

Looking ahead … Plans for 2010


Expand the capabilities and content of the SEO online systems database and
coordinate closer with ESA's CEOS MIM database.


Complete the first release of a Google
-
Map coincident imaging tool (COVE) to
support WGCV.


Complete a Mid
-
resolution LSI Constellation standards document. (
see LSI
presentation
)


Work with the JAXA SIT team to conduct system requirements and gap
analyses for strategic planning.


Revise the WGEdu portal and develop new EduFlow educational products for
enhanced capacity building.

(
see WGEdu presentation
)


Implement a new online action tracking tool for CEOS management.


Continue progress on a Climate Pilot Project to understand decision support
uncertainty.

CEOS MIM Database
(ESA
-
developed)


Online DB of CEOS agency Missions,
Instruments and Measurements (MIM).


Filter and Search capabilities.


Measurement timeline tables.


Export to EXCEL.


Plans to update agency data
annually.


Future plans to consider EO Portal data, and

CEOS Systems Analysis Database
(SEO
-
developed)


Includes MIM data from ESA. Adds more
sorting and filtering capabilities.


Links MIM data to CEOS Constellations, GEO
SBAs (GEOSS 10
-
Yr Plan requirements), GCOS
ECVs (climate variables).


Gap Analysis tables designed to support
strategic planning.


Future plans to add WMO requirements and
GEO UIC SBA requirements.

CEOS Visualization

Environment (COVE)

Background


COVE is a Web
-
based Google
-
Earth Coincident Imaging Tool
for Satellite Calibration and Validation (Cal/Val) developed
by SEO for WGCV.


COVE supports on
-
orbit and ground
-
based Cal/Val of CEOS
missions to improve data continuity, interoperability, and
data fusion by calculating coincident viewing events for
multiple satellites.


COVE is a systems engineering tool with broad international
interest for enhanced collaboration and data evaluation.


Prototype version now available for testing and validation.

Features


Simple and intuitive Google
-
Earth interface with dynamic
menus, multiple viewports, and a Mission Database.


Rapid calculation of coincident events and orbit
groundtracks


User
-
defined evaluation periods and regions of interest


Multi
-
user collaboration and EXCEL table output format

SEO working with JAXA (SIT Chair team) to develop a Strategic Gap Analysis Implementation Plan for CEOS.


The assessment of gaps will be based on missions capabilities vs. user requirements from decision
-
makers,
information product and service providers, scientists, and modelers.


3 types of gaps: lack of measurement continuity (time series), lack of individual measurements, lack of science
knowledge or applications due to missing measurement groups.


CEOS agencies can make a significant impact on gaps by selecting annual high priority topics for analysis and
developing solution action plans.


The SEO has developed a prototype gap analysis for CO
2

to learn more about the gap analysis process.


Common mission timelines DO NOT accurately reflect gaps (
see timeline above
),


An evaluation of detailed user requirements is needed to conduct a valid gap analysis.


Consider instrument types (measurement approach), spectral bands, resolution (space and time), data product
quality, and science requirements such as atmospheric layers.


The SEO has a one
-
pager with more detailed results of a preliminary CO
2

gap analysis (
see Shelley Stover
)

Climate Pilot Project:
Assessing Impacts of Uncertainty in Climate
Observations and Model Projections on Decision Support


Understanding uncertainty will
improve our ability to use Earth
observation data for key
decisions and improved societal
benefit.


This project is focused on
assessing uncertainty in climate
observations and the impact of
those uncertainties on decision
support tools and key issues
confronting local decision
-
makers.


A rapid prototype project
utilizing Global Circulation
Models (GCMs) and a Regional
Climate Model (RCM) with
agricultural decision support in
Central America is considered.


The results of this project will
improve risk
-
informed decision
making on water resource
management and strategic
resource investments that
consider uncertainty in the
decision making process.

Option #1:

CEO EXCEL Table
(current approach)


Comprehensive database of action item content with EXCEL
-
based
functions.


Single file with all actions emailed to POCs.


Features added recently e.g. to visualize only POC’s actions with one click


Single person (CEO) controls the latest version.


Not available online.

Option #2
: SEO Action Tracking Tool


Web
-
based tool intended to mirror the current EXCEL
database.


Functions similar to EXCEL but not quite as powerful.


Available online (CEOS website) for viewing and editing.


Version control and user editing control.


Prototype version available with EXCEL output.

Option #3
: CEOS Website
(Joomla
-
based)


Use existing Joomla
-
based CEOS website to post
individual articles for each action.


Allows user editing online by any registered user.


Most effective for a small (< 20) number of actions.


No version control or EXCEL output.

Action Plan



Use Option #2 starting in
Jan
-
2010 after the new
CEOS actions are approved.


Continue to study Option
#3 for the future.
