GOFC SDI Issues GOFC T. Fisher
GOFC 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
Three primary components • Forest fire monitoring and mapping • Forest cover characteristics and changes • Forest biophysical functioning
Forest 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 changes • 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 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
Wildland Fire in Canada • 10,000 fires per year • 2.5 million ha burned annually • $500 million fire management cost • 20% of forest management costs

Core SDI Issues • Access / Framework Data / Standards / Policy / Partnerships GOFC Issues • User interface standards/design • Network connectivity, availability and bandwidth • Interoperability standards, etc. • Common base map • Archives of historical data (especially AVHRR)
