Mapping deforestation in Amazon with ERS SAR interferometry

Deforestation in a part of Rondonia State in the Brazilian Amazon has been mapped by means of ERS SAR interferometry. The thematic information of the one day coherence, the backscattering intensity and the temporal change of backscattering intensity were used jointly in this analysis. The results show that along the Cuiaba-Porto Velho road a large area has been deforested for timber extraction, shifting cultivation and permanent agriculture and pasture.
