Assessing oil pollution using traditional field-based methods over large areas is difficult and expensive. Remote sensing technologies with good spatial and temporal coverage might provide an alternative for monitoring oil pollution by recording the spectral signals of plants growing in polluted soils. Total petroleum hydrocarbon concentrations of soils and the hyperspectral canopy reflectance ...

We investigated the potential of hyperspectral remote sensing to estimate aboveground biomass (AGB) over Brazilian savannas (Cerrado), second-largest source carbon emissions in Brazil. For this purpose, a Hyperion/Earth Observing-1 (EO-1) image was collected dry season at Ecological Station Águas Emendadas (ESAE). In order AGB, we evaluated performance five machine learning models (Classificati...
