Abstract
This study performed comparison of spatial distribution of oil spill using simulation and satellite data which acquired after Hebei Spirit oil spill on Dec. 2007. In order to extract the oil spill data, five satellite images, KOMPSAT-2 MSC(Dec. 8), ENVISAT ASAR(Dec. 11 and 14), RADATSAT-1(Dec. 11) and TerraSAR-X(Dec. 13) were used. Oil particles has extracted in oil spill area using equal interval grid. The wind is used a mean value of wind speed and direction that measured at 19 stations around accident area. The tide is used a calculated value with 30-minute interval from EFDC model. And they are used as initial and referential data of simulation. Tidal current and wind data were used as driving forces to simulate movement of oil particles, but other environmental conditions, such as waves, turbulence, salinity, temperature and solar insolation, were not considered in simulation.Simulated and extracted data are converted to binary format in order to compare spatial distribution using coordinates and calculated the accuracy based on quantitative analysis. The results of comparison represent that as wind speed was raised, wind component rate was linearly increased.MSC(Dec. 8), ENVISAT ASAR(Dec. 11 and 14), RADATSAT-1(Dec. 11) and TerraSAR-X(Dec. 13) were used.
