                         imagery is challenging with the benefit to provide valuable 
                         insights for ecologists and land managers. Hyperspectral data 
                         proved to be feasible for this task, but it is still unclear how 
                         different classification methods perform. In this work, we 
                         evaluated Linear Discriminant Analysis (LDA), Radial Basis 
                         Function Support Vector Machines (RBF-SVM) and Random Forest (RF) 
                         for tree species discrimination and mapping in a tropical forest 
                         using airborne hyperspectral data. The effects of dimensionality 
                         reduction on classification performance were also assessed by 
                         selecting sets of 10, 20 and 30 bands. At the pixel level, LDA 
                         performed better than other methods (Average Accuracy (AA) =84.7%) 
                         using all (260) spectral bands for classification. However, 
                         RBF-SVM produced the best map of species using 30 selected bands 
                         (AA =90.4%) in an object based approach (OBIA). OBIA increased the 
                         AA of species mapping for all tested methods and reduced spatial
