Generation and Mapping of Fuel Types for Fire Risk Assessment

Fuel mapping is key to fire propagation risk assessment and regeneration potential. Previous studies have mapped fuel types using remote sensing data, mainly at local-regional scales, while smaller scales has been based on general-purpose global databases. This work aims develop a methodology for producing maps across European regions improve wildland assessment. A map regional-continental scale proposed, Sentinel-3 images, horizontal vegetation continuity, biogeographic regions, biomass data. the Iberian Peninsula Balearic Islands was generated with 85% overall accuracy (category errors between 3% 28%). Two were generated: (1) 45 customized types, (2) 19 adapted Fire Behaviour Types (FBFT) system. The mean values of final parameterized fuels show similarities other products, but do not present strong correlation them (maximum Spearman’s rank correlation: 0.45) because divergences in existing products terms considering forest overstory or not.
