The oil spill diagnosis of Dalian New Port sea based on multi source remote sensing data

Abstract:

The oil spill information of the Dalian New Port on Jul. 16, 2010 was extracted and analyzed by MODIS and Radarsat 2 remote sensing data. After the pre processing of MODIS remote sensing data, take measure of band math to extract oil spill information. For higher resolution Radarsat 2 remote sensing data, after the pre processing of geometric correction, filtering and so on, take the method of texture analysis to extract oil spill information with the obvious boundary, then compared with the extracting oil spill result in MODIS remote sensing image, eliminate the non oil information in MODIS remote sensing image, so it can complement each other’s advantages by using the two remote sensing data. For MODIS data on Jul. 18, 2010 and Radarsat 2 data on Jul. 19, 2010, the extracted oil spill area which is calculated by the ArcGIS software is 174 km2 and 198 km2, respectively, which is according with the report of the China Ocean Monitoring Ship, so that it shows the feasibility of this method.
