The oil spill and oil slick in the Gulf of Thailand were detected using the ENVISAT/ASAR and MODIS data. With other environmental data of seasurface wind, oceanographic surface current and weather map in the same time of satellite data, the SAR data were analysed on entropy, energy, homogeneity and filtering by Lee and Gamma method. The density of oil slick in the Gulf of Thailand for possibility of occurrence is mapped in order to find the risk area.The potential of ASAR and MODIS data were comparison to detect the oil spill in the Gulf of Thailand.
