              Terms of Reference- GEO User
                  Interface Committee
Goal
• To engage users in the development and
  implementation of a sustained GEOSS that provides the
  data and information required within and among the
  nine societal benefit areas as specified by user groups
  on national, regional and global scales
Also a specific goal to address cross-cutting issues and
  oversee the Communities of Practice (CPs), ensuring
  continuity & avoiding duplication.

                            UIC Objectives

• Enable GEO to address in a systematic, targeted, focused and
  comprehensive way the needs and concerns of a broad range
  of user communities in developing and developed countries,
  across issues and trans-disciplinary needs, with a particular
  focus on fostering new or less organized communities.
• Enable GEO, in the implementation of GEOSS, to engage a
  continuum of users, from producers to the final beneficiaries
  of the data and information
• Facilitate linkages and partnerships between established CPs
  and new user groups or organizations interested in
  collaborating.

                  GEO TASK US-06-01

Establish a GEO process for identifying
 critical Earth observation priorities
 common to many GEOSS societal
 benefit areas, involving scientific and
 technical experts, taking account of
 socio-economic factors, and building on
 the results of existing systems’
 requirements development processes.

         UIC Meeting August, 2007
        A Process for TASK US-06-01

The User Requirements Gathering Processes
• Presentation by Dr. Lawrence Friedl

User Needs and System Performance Utility
  (UNSPU) Proposed Functional
  Specifications
• Presentation by Dr. Hans-Peter Plag
   Canada Centre for Remote Sensing         Earth Sciences Sector


                    The User Requirements
                     Gathering Processes
• A 2-year timeline of US-06-01 activities .
• How an “Advisory Group” and an “Analyst” will
  work together to develop the priorities within each
  SBA. The analyst will be the primary coordinator
  and organizer of the activity to meet the schedules,
  and will interact with and utilize the Advisory
  Group for each SBA.
• UIC’s Refined Process in nine steps.
• Explanation that the process “harvests”
  observation needs expressed in existing documents.
   Canada Centre for Remote Sensing         Earth Sciences Sector




              The Nine Steps for US-06-01

1: For each SBA, UIC Members identify Advisory Groups
   & Analysts who identify/develop the following
2: Scope of topics for the current priority-setting activity
3: Existing documents on observation priorities
4: Analytic methods and priority-setting criteria
5: Priority observational needs from documents &
   interviews
6: Combine the information & develop a preliminary
   priorities report
7: Gather feedback on the preliminary report
8: Perform any additional analysis
9: Complete the report on Earth observation priorities

For success,
§ The benefits of GEOSS will be realized globally by
  a broad range of user communities
§ User needs will drive Architecture, Data
  Dissemination, Capacity Building, etc.
§ Engagement of users in developing countries will
  maximize their opportunities to derive benefits
  from GEOSS.

                 Communities of Practice


A user-led community of stakeholders, from providers to the
final beneficiaries of Earth observation data and information,
with a common interest in specific aspects of societal benefits to
be realized by GEOSS implementation.



The Communities of Practice will be self organized and will
include stakeholders required to achieve benefits.

                 Communities of Practice
Objectives:
Each CP will have slightly different objectives but of necessity
  there will be common objectives such as:

• To provide a forum for discussion and to identify, gather,
  and seek agreement on their particular user community
  requirements;
• To identify linkages and opportunities for collaborative
  strategic and technical projects.
• Coordinate the target delivery to enable the realization of
  societal benefits
• To advise the User Interface Committee, GEO Plenary and
  all other CPs on matters relating to their particular area of
  interest or societal benefit.
