  abstract = {{T}he {S}upport {V}ector {M}achines ({SVM}) are increasingly far-reaching in remotely sensed data classification. {A}s supervised classifiers, the {SVM} output depends on the input pixels, pointing out that training is potentially an important stage for optimizing classification accuracy. {T}he {SVM} consist in projecting pixels into a high-dimensional feature space and then fitting in a hyperplane, maximizing the distance between the closest vectors and the hyperplane itself. {T}his study aims to locate the pixels acting as support vectors and identify the ecological features they contain in a tropical vegetation context. {T}he analyses focused on a {Q}uickbird-2 image where two vegetation types occur. {T}he physical boundary between classes was delineated in the field, and we used an iterative method to mark and localize the pixels acting as support vectors on the image. {O}ur results highlight that vegetation sampling should focus on ecotones (the transition area between two different and adjacent vegetation classes) in order to minimize the field survey effort and maximize the mapping accuracy.},
