Talk Outline GOFC-GOLD Regional Networks what where why how Food for thought in making decisions for E. Europe NASA LCLUC Program
Organizational Structure Executive committee Tony Janetos, Chair (John Townshend former Chair) Two implementation teams Land Cover Characteristics and Change (M. Herold and C. Woodcock) Fire Monitoring and Mapping (J. Goldhammer and C. Justice) Working groups Biomass Monitoring Reducing Emissions from Deforestation and Forest Degradation (REDD) Other Regional networks Coordinators: Olga Krankina and Anja Hoffman (fire)
Role of Regional Networks in GOFC/GOLD Formulate regional requirements Observations (measurements) Derived products and their associated accuracy requirements Distribution systems Evaluate the utility of global LC and Fire products for regional use Participate in regional product inter comparison and validation initiatives (providing local expertise) Feedback to producers Facilitate regional use of remotely sensed data and products Web site e.g. links to GOFC-GOLD-Fire and land cover websites Establish regional data dissemination nodes Encourage standardization and harmonization of regional products Outreach workshops with regional practitioners and decision makers Coordinate regional capacity building and training of users Promote technology transfer and collaborations within countries and regions
Regional Networks a critical component of the implementation of GOFC-GOLD Providing the interface between the Implementation Teams and data users in the regions GOFC-GOLD ExCom and ITs GOFC-GOLD GOFC-GOLD Regional Regional Networks GOFC-GOLD Regional Networks Networks National Needs and National Needs and National Users Needs and National Users Needs and National Users Needs and Users National Within the Needs Region and Users Within the Region Users Within the Region 1.

Network Activities Regional Workshops are the main activity GOFC-GOLD Regional Network Data Initiative Landsat Data Archive at USGS is free! Access is difficult in regions with inadequate internet access Disseminate Landsat data Provide training in use of remotely sensed data 2 Data Intitiative workshops in USA Africa Pilot Workshop (2009) Data Initiative - Asia (2010) Data Initiative-3 (Africa, SE Asia, S. America) April-May 2012 Network Projects
GOFC-GOLD Regional Network Data Initiative Pilot for Africa Involves 5 regional networks Network representatives received data and training over 3 weeks at USGS EDC, South Dakota State University (SDSU), UMD in April-May 2009 Support provided by NASA, START, USGS, UNEP, SDSU and CFS
GOFC-GOLD Regional Network Data Initiative Asia Workshop Two regional networks: CARIN and SEARRIN (6 representatives) Training over 3 weeks at USGS EDC and SDSU or OSU in May 2010 EDC set an all-time record for Landsat downloads in a single day at 8000 scenes E.g., Kazakhstan archive: >14 thousand images for 483 scene positions (1972-2010)
Landsat TM and ETM (1984-2010) coverage for Central Asia in CARIN-Kazakhstan Archive (colors indicate number of scenes for each path/row): 1 Kazakhstan; 2 Russia; 3 Uzbekistan; 4 Turkmenistan; 5 Kyrgyzstan; 6 Tadzhikistan; 7 Afghanistan; 8 Mongolia; 9 China; 10 Iran; 11 Pakistan; 12 Azerbaijan; 13 Georgia.
