- Abstract
- The PRIMI project funded by the Italian Space Agency (ASI) has implemented an observation and forecast system
to monitor marine pollution from hydrocarbon oil spills (OS) in the Italian Seas. The system consists of four components,
two of which for OS detection via multi-platform SAR and optical satellite imagery, an OS displacement
forecast subsystem based on numerical circulation models and a central archive that provides WEB-GIS services
to users. The system also provides meteorological, oceanographic and ship detection information. The Optical Observation
Module, based on MODIS and MERIS imagery, is described here. The idea of combining wide swath
optical observations with SAR monitoring arises from the necessity to overcome the SAR reduced coverage of the
monitoring area. This can be done now, given the MODIS and MERIS higher spatial resolution with respect to
older sensors (250-300 m vs. 1 km), which consents the identification of smaller spills deriving from illicit discharge
at sea. The procedure to obtain identifiable spills in optical reflectance images involves removal of natural
variability to enhance slick - clean water contrast, image segmentation/clustering and a set of criteria for the elimination
of those features which look like spills (look-alikes). The final result is a classification of oil spill candidate
regions by means of a score based on the above criteria. (literal)
