GBA-2000 Product definition • a binary map (burnt-unburnt) monthly non-accumulative global burn scar map, at 1 km resolution • statistics of burnt areas area burnt in 2000 per country, per month, and • per main types of vegetation cover (UMD & GLC2000)
GBA-2000 General approach • 7 co-investigatorsCSIRO, CCRS, IFI, CNR, UTL, GVM, NRI • regional algorithms for processing VGT S1 to burnt area maps • integration into a global processing chain(at JRC) • processing of the complete global time series (at JRC) • production of monthly global maps & statistics(at JRC) • GBA2000 products publicly available(IMS at UNEP-GRID)
GBA-2000 Regional algorithms & Global processing chain • 5 regional algorithms have been selected • the moist tropical forest remains a problem • the global processing chain is complete and running • for more information • Kevin Tansey at GVM/JRC kevin.tansey@jrc.it • Grégoire et al., 2002
