چکیده

Synthetic aperture radar (SAR) data from RADARSAT-1 are an important operational data source for several ice centres around the world. Sea ice monitoring has been the most successful real-time operational application for RADARSAT-1 data. These data are used by several national ice services as a mainstay of their programs. Most recently, Canadian Ice Service launched another new real-time operational program called ISTOP (Integrated Satellite Tracking Of Pollution). It uses the RADARSAT-1 data to monitor ocean and lakes for oil slicks and tracking the polluters. In this paper, we consider the ice information requirements for operational sea ice monitoring and the oil slick and target detection requirements for operational ISTOP program at the Canadian Ice Service (CIS), and the potential for RADARSAT-2 to meet those requirements. Primary parameters are ice-edge location, ice concentration, and stage of development; secondary parameters include leads, ice thickness, ice topography and roughness, ice decay, and snow properties. Iceberg detection is an additional ice information requirement. The oil slick and ship target detection are the basic requirements for the surveillance and pollution control.

Operational Satellite Monitoring and Detection for Oil Spil in Offshore of United Arab Emirates

Many satellite-borne image data have been acquired in the Arabian Gulf since the mid 80’s by different space agencies and have demonstrated oil spill related features at sea. Severe oil spills were caused occasionally by accidental or deliberate oil sludge dumping from passing ships. Serious damage to fishery, water desalination plants and natural habitats are concerned. The work done is the fi...

Comparison between Mahalanobis classification and neural network for oil spill detection using RADARSAT-1 SAR data

Oil spill or leakage into waterways and ocean spreads very rapidly due to the action of wind and currents. The study of the behavior and movement of these oil spills in sea had become imperative in describing a suitable management plan for mitigating the adverse impacts arising from such accidents. But the inherent difficulty of discriminating between oil spills and lookalikes is a main challen...
