SYNMAP – for carbon cycle modeling
SYNMAP – a global synthesis product of existing global land cover maps to provide a targeted and improved land
cover map for carbon cycle modelling purposes; here shown as life form assemblages (Source: M. Jung et al.

DS-10 Global Land Cover
DefinitionPrepare and improve access to, among Member and Participating Organization communities, global and regional information encompassing cross-cutting data sets such as land cover and land use information (Data Management Target)Increase operational monitoring of major ecosystems on land on an annual basis, including properties such as land cover type (Ecosystems Target)Improve collaboration and coordination on the use and applications of Earth observations for land cover mapping (Agriculture Target)Ensure the availability of all Essential Climate Variables needed by the WCRP, the IPCC and the UNFCCC (Climate Target)
Deliverables
1. A global moderate‐resolution land-cover monitoring system
Priority Actions: – Produce global land-cover (<50m) continuous fields,
types, and changes, together with annual and bi‐decadal maps and statistics
– Improve the use of time-series products and validate moderate resolution and land-cover datasets such as GLOBCOVER and MODIS
Leads: GOFC-GOLD, US, China, EC
Deliverables
2. Access to historical land-cover imagery and global high‐resolution coverage obtained through international acquisitions coordination. To be implemented in connection with IN-01 (GCI) and ID-01 (Data Sharing)
Priority Actions: Support retrospective land cover mapping and change analyses
Leads: Land Cover Leads
Deliverables
3. Essential Climate Variable (ECV)
Priority Actions: Generation of ECVs at multiple resolutions
Leads: GCOS, US …

Re-organization of 2009-2011 Sub-tasks
(i.e. which sub-tasks support the new Task)
• This is an expansion of the current GEO Global Land Cover Task (DA‐09‐03a) that focused on coarse‐resolution global land cover, improved land cover specifications, and capability building.…
Resources Available for Implementation
(current status and in planning)
• US: Financial resources for development of global land cover products (~$1 million/year from USGS expected) with other contributions TBD, expanded access to comprehensive global 30m remotely sensed data.…
• China
Issues and Gaps• Calibration/Validation Data• Funding and funding continuity• Flexibility of data sources and scales• Activities moving from independent datasets to synergy
products need to continue • Datasets can be produced on continuous basis• Comparative & operational accuracy assessments:
– Synergy and “best” available datasets and information– Regional accuracy numbers – Error propagation and more user-relevant uncertainty
analysis
Possible Measures to fill Gaps
– international community consensus building– Support ongoing monitoring projects (data continuity)– Invest in better user interactions and data uptake
Open for Plenary Discussion
→ Identify Synergies
→ Improve Cross-Fertilization
→ Identify Measures and Actions to Fill Gaps
