Abstract :
This study focuses on improving information about oil spill environmental sensitivity in Western Amazonia, Brazil, using a pair of multiseasonal (1995 low flood to 1996 - high flood) GRFM JERS-1 SAR mosaics. Fuzzy analysis is carried out to extract information about landscape modifications within half hydrological cycle. The oil spill hazard information derived from JERS-1 SAR data is straightforward to interpret and constitutes a representation of the original Environmental Sensitivity Index (ESI) product conceived by PETROBRAS.
