  remotely-sensed Earth science metadata
• Maintain and update the content of the IDN
• Control and update the Directory Interchange
  Format standard
• Support the IDN Coordinating Cooperating nodes,
  including s/w upgrades

23
What the GOFC Team is Proposing

• Assembling existing datasets
• Demonstrations of operational forest monitoring
  through prototype projects
• Develop consensus algorithms and standard
  methodologies
• Co-ordination and articulation of user
  requirements
• Working toward ongoing operations

24
Three primary themes

• Forest fire mapping and monitoring
• Forest cover characteristics and changes
• Forest biophysical functioning

25
Forest fire mapping and monitoring

• Near-real-time monitoring of fires
• Post-season mapping of large burned areas
• Can build on current capabilities and plans
  (FireM3, World Fire Web, MODIS fire products)
• Provides rapid indication of forest cover change
• With additional modelling, can provide
  information on carbon emissions.

26
Forest cover characteristics and changes

• Combines global coverage at coarse resolution
  with targeted coverage at fine resolution
• Wall-to-wall coverage of forests every 5 years
• Sophisticated data acquisition strategy using
  coarse resolution optical (250 m - 1 km), fixed
  and pointable fine resolution optical (20-30 m),
  and microwave sensors
• Forest cover characteristics leaf type, leaf
  longevity, per-cent canopy cover, canopy height
• Forest cover change forest to non-forest,
  non-forest to forest, and no change

27
Forest biophysical functioning

• Global coverage with coarse sensors
• Desired products LAI, PAR, FPAR, NPP, forest
  biomass
• Additional research is needed
• GOFC can facilitate international liason
• New sensor(s) are desirable for forest biomass
• Vegetation Canopy Lidar
• P-band SAR

28
GOFC recommendations to CEOS

• Provide and process essential data
• Support technology and documentation
• Promote co-operation
• Provide leadership for pilot projects

29
Provide and process essential data

• Acquire and process the data needed to accomplish
  GOFC objectives
• Work co-operatively to ensure long-term
  continuity of essential data
• Promote the development and implementation of
  efficient production systems to lower the cost of
  large-volume earth-observation datasets
• Sensor development
• Improve coarse resolution to 250 - 500 m
• New sensor(s) for forest biomass
• P-band SAR

30
Support Technology and Documentation

• Encourage CEOS members to provide user-friendly
  on-line facilities to access metadata and
  quicklook images for all archival data (with
  WGISS)
• Promote the standardization and documentation of
  data products from optical and SAR satellites
  (with WGISS)
• Support RD to develop a capability to estimate
  forest biomass from space.

31
Promote Co-operation

• In co-operation with GTOS and TOPC, help expand,
  establish, and maintain a network of test sites
  to validate GOFC experimental products (with
  WGCV)
• Develop a relationship with research, forest
  management, and policy agencies to facilitate,
  for example, reporting for international
  protocols and treaties.
• Develop and document calibration/validation
  protocols for earth-observation data and derived
  products generated for GOFC (with WGCV)
• Facilitate a constructive relationship with
  vendors of hyperspatial resolution (1-3m) data.
  This will assist in the validation of derived
  products.

32
Current status

• On-going interactions with CEOS-SIT
• Primary focus on carbon sinks
• Canada joining World Fire Web project through
  FireM3
• Exploring possible pilot projects for Forest
  Cover Characteristics and Changes
• GOFC Website online
• GOFC Data Site Under Construction at CCRS

33
CINTEX Support of IGOS GOFC

• GOFC Catalog Interoperability Needs
• An interoperable catalogue system, distributed
  amongst participating agencies for accessing data
  of value to GOFC
• A protocol to allow search, retrieval and
  ordering of data of interest to GOFC
• GOFC Design stage now, prototype for next two
  years
• Initial Analysis of GOFC Framework
• Uniform, international access to datasets through
  a virtual data access layer
• Catalogue Interoperability Protocol (CIP) as
  uniform protocol, attributes, schema
• Interoperable Catalogue System (ICS) access to
  datasets of interest to GOFC
• Multiple options for Data Providers to Join
