GOFC Strategic DesignGOFC Strategic Design
• Primary GOFC contribution for 1998
• Illuminates the way forward
• Does not provide a detailed blueprint
• Implementation depends on voluntary contributions of participating agencies

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

Forest cover characteristics and Forest cover characteristics and changeschanges
• Combines global coverage at coarse resolution with targeted coverage at fine resolution;
• Wall-to-wall coverage of forests every 5 years (with coarse and fine data);
• 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.

Forest biophysical functioningForest biophysical functioning
• Global coverage with coarse sensors;
• Desired products: LAI, PAR, FPAR, NPP, forest biomass;
• Additional research is needed;
• GOFC can facilitate international liaison;
• New sensor(s) are necessary for forest biomass:
– Vegetation Canopy Lidar
– P-band SAR
