This work approaches geobotany in southeastern Brazil within terrains comprising Forested Savannas, Gallery and Riparian Atlantic forests developed over fluvial-lacustrine sediments and rocks. The notion was to test the ability of SpecTIR V-S hyperspectral imagery (357 VNIR-SWIR channels; spatial resolution of 1m) to identify the variation of clay content(More)
