Wildland fuel distribution and characteristics are critical components for the development of a national integrated wildfire management strategy. This study presents methodological framework mapping fuels in Mediterranean ecosystems different levels new hierarchical classification scheme, using spectral–spatial approach based on Sentinel-2 timeseries auxiliary thematic maps. Furthermore, context this research, novel is proposed separating shrubland vegetation into three broad height categories, images, landscape variables, climatic data. Two areas Greece, namely Attica Euboea, with major events over past 3 years were selected as areas. The methodology was designed to consist complementary processes, each identification specific types (i.e., urban, agricultural, vegetation). results validated two-step scheme. first level display an overall accuracy 88% kappa 0.84, while second level, 71.64% 0.68. Our research demonstrates capacity map promising at depths, highlighting viable method that can be potentially exploited large-scale biomes level.
