However, traditional weather-based indices cannot render information on the spatial distribution of fire-susceptible sites over extensive forested areas because their only inputs are meteorological observations made at sparsely...
In the north of Tunisia, mine tailings cause multiple environmental consequences in the Mejerda watershed. In this paper, we are interested in mine tailing mapping around the Jebel (Hill) Hallouf-Bouaouane mine. Several ways to estimate the spectral reflectance for end-members in a mixture problem have been proposed in the literature such as pure pixels, spectral library, and field measurements. One...
