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
