ABSTRACT

The present work deals with a comparative analysis of the two main atmospheric correction methods for AVIRIS hyperspectral imagery: the Green and the ATREM methods. It is also analysed the procedure EFFORT, associated to the atmospheric correction, which is applied after the correction in order to eventually filter atmospheric residues. It is shown that the Green's Method presented better results, compared to the ATREM Method. The use of the EFFORT procedure produced a significant improvement on the ATREM's results, but the improvement on the Green's Method results was moderate.
