LSI Constellation:

Goal 1: establish agreements,

among space agencies currently

operating mid-resolution land

surfacing imaging satellite systems, to

cooperate more closely together to

operate those systems as a real

prototype Land Surface Imaging

Constellation;

Goal 2: develop preliminary

guidelines for a mid-resolution Land

Surface Imaging Constellation; and

Goal 3: meaningfully contribute to the

production of a fundamental

climate data records by providing

mid-resolution LSI data to support

GEO and CEOS priorities.

Presentation Outline

4 The 24th CEOS Plenary – Rio de Janeiro, Brazil 12-15 October, 2010

• Expand functionality to include cross-system,

granule-level, search and data retrieval

– Highest priority: The addition of a prototype map-based query

and direct data download capability to the Portal using CWIC as

the interface to the member data systems.

– CWIC will provide an access point for major CEOS agency

catalog systems.

– CWIC will distribute inventory/product searches to the CEOS

agency inventory systems using the agency systems native

protocol.

– Need support for a java programmer to support SIT demo in

2011

LSI Portal Enhancement Proposals

6 The 24th CEOS Plenary – Rio de Janeiro, Brazil 12-15 October, 2010

• Addition of new data types or descriptive

information (Second priority)

– Link to Working Group on CAL/VAL portal and others. Value

of having more synergy at the LSI portal level with WGISS and

WGCV, especially as multisource/multisensory applications are

developed. Additional information on calibration coefficients and

spectral response functions (or links to relevant information such

as mission web pages and cal/val sites) would be valuable and

a unique asset to the LSI portal or links to WGCV subgroup on

Infrared and Visible Optical Sensors.

– Expanding the data set, sensor, and platform information as

well as links to order/access systems for other optical land

imaging systems such as MODIS.

8 The 24th CEOS Plenary – Rio de Janeiro, Brazil 12-15 October, 2010

• In 2008, the LSI Constellation initiated an effort to define guidelines that define a set of ideal or optimal guidelines for mid-resolution optical mission, instrument, and data policy characteristics.

– It is recognized that no single mission or ground segment would be expected to meet all of these guidelines. Instead, the overall virtual constellation of LSI would together achieve these goals through the combination of their specific subset of specialties and foci.

• Guidelines to be based on the needs of the land imaging user communities (vegetation, solid earth, water, geo-hazards).

• Systems Engineering Office has been supporting the LSI Constellation

– Multiple iterations worked with LSI Co-Chairs

– An assessment of the currently flying instruments and their spectral band coverage is in progress to determine what is already being measured

LSI Mid-Resolution Optical Guidelines

9 The 24th CEOS Plenary – Rio de Janeiro, Brazil 12-15 October, 2010

• Use 1: A CEOS agency has an

instrument already built that they

feel will benefit the LSI Community.

They go to the guidelines

document to learn about where

they would fit with other LSI

instruments and to determine if

they are filling a needed niche.

• Use 2: A CEOS agency would like

to build an instrument to achieve

LSI goals. The instrument design

team goes to the guidelines

document to see what the

instrument characteristics should

be.

• Therefore address

questions such as:

– Who are the users?

– What kinds of instruments?

– What kinds of

measurements?

– What SBAs are related?

– What spectral bands are of

interest?

– What are current missions?

– What are the future

missions?

– What are the guideline

values for measurements?

LSI Mid-Resolution Optical Guidelines

10 The 24th CEOS Plenary – Rio de Janeiro, Brazil 12-15 October, 2010

• The document includes:

– Measurements, User Communities, and SBA’s

– Measurements and Instrument Types

– Measurements and Spectral Bands

– Mid-Resolution Optical Missions

– Missions and Measurements

– Measurement Guidelines

– Measurement Expected Performance

– Systems Analyses

Next Steps

• Draft discussed at Montreal LSI Study Team Workshop, Friday

afternoon, 17 September 2010

• Community review of document by 1 October 2010

• sent to WGISS and WGCV for comment

• Updated draft of document in-work

• Comments from community review being addressed

• Analysis and updates ready for SIT-26 in March 2011

– Both tools will be made available as freeware software.

1. Command line tool (windows and linux):

– Two geometrical models: Rigorous Mathematical Model and RPCs

(Rational Polynomial Coefficients)

– already implemented and tested

– documentation (installation and users' manuals) in English are

being revised

– definition of website link for download still pending

• SPRING: Freeware GIS and remote sensing image

processing system (English, French, Spanish,

Portuguese)

GEO Forest Carbon Tracking

GEO FCT Background

• The GEO Forest Carbon Tracking initiative seeks to develop a global framework for a system of national systems for forest carbon tracking in support of the inclusion of forests in a post-Kyoto climate agreement

• Satellite and in-situ data are an essential element of the Monitoring, Reporting and Verification (MRV) systems that will be employed in the regulatory framework for such an agreement

CEOS role

• CEOS is demonstrating that the technical capacity and institutional frameworks are in place to ensure continuity of the required satellite observations in support of post-Kyoto regulatory frameworks

• 7 National Demonstrator (ND) countries have been the subject of a coordinated satellite data acquisition effort by CEOS agencies in 2009 – with complete coverage achieved for both radar and optical data and 4 new NDs have been added in 2010

• A demonstrator portal showing available data and forest carbon datasets has been developed: portal.geo-fct.org

Current Challenges

• Acquisition strategy for GEO FCT involves a continuation of

and an expanded demonstration mode in 2011 and 2012

– Full Commitment from All CEOS LSI Member Agencies needed

• GEO FCT Gap filling strategy for land imaging data if Landsat 5

and 7 fail prior to LDCM launch.

• Can LSI achieve Objective 1 “…land surfacing imaging satellite

systems, to cooperate more closely together to operate those

systems as a real prototype Land Surface Imaging Constellation.”

– Can the planned “core data systems” operate as a virtual constellation?

• Will Space Agencies adjust acquisition strategies?

• Will future missions adjust sensor/mission plans?

– Will free and open data access policies be adopted by more CEOS

members?

Requests of CEOS Space Agency Data Support

GEO Task AG-07-03 - Agriculture

• Global Agricultural Monitoring System of Systems, jointly led by Canada, the European Commission, and the United States.

• Provides a much-needed framework for a concerted international effort to improve global agricultural monitoring capabilities and enhance food security through the use of remote sensing data.

• The implementation of the GEO Task AG-07-03 requires free, open, and timely access to satellite data and products for global agriculture monitoring.
