eng Airborne Hyperspectral Surveillance of the Ship-based Oil Pollution in Croatian Part of the Adriatic Sea

hrv Zrakoplovni hiperspektralni nadzor uljnog onečišćenja s brodova u hrvatskom dijelu Jadranskog mora

eng The airborne hyperspectral and multisensor surveillance of the ship sourced oil pollution of the sea was researched by the airborne system developed in the frame of the project „System for the multisensor airborne reconnaissance and surveillance in crisis situations and the protection of the environment“ (MZOS 2007). While different methodologies, methods, technologies and techniques were used, the multilevel fusion was applied for linking the data, the processes and the outcomes. Fusion includes the aerial hyperspectral and the colour imagery, the visually detected oil spills, the formalised knowledge for the estimation of the oil spill area and oil’s quantity based on Bonn Agreement Oil Appearance Code – BAOAC, the data about the spectral response of the clean sea and polluted sea, the results of hyperspectral classification. Besides the information acquired by the airborne multisensor system, the information provided by space based system CleanSeaNet of the European Maritime Safety Agency – EMSA was included in the fusion process (in the frame of the large trial – operational exercise in 2008). The advantages of the airborne remote sensing of the oil spills are reliable detection of the oil spills, accurate mapping of its position and the shape in geographic coordinates, classification of the contents of the spill, measurements of the oil spill’s features, estimation of the oil quantity.

hrv Istražen je hiperspektralni i multisenzorski nadzor uljnog onečišćenja mora s brodova pomoću zrakoplovnog sustava razvijenog u okviru projekta “Sustav za multisenzorsko zrakoplovno izviđanje i nadzor u kriznim situacijama i zaštiti okoliša” (MZOS 2007). Budući da su korištene različite metodologije, metode, tehnologije i tehnike, primijenjena je višerazinska fuzija za povezivanje podataka, procesa i njihovih izlaza. Fuzija uključuje zrakoplovne hiperspektralne i kolor snimke, vizualno detektiranu uljnu mrlju, formalizirano znanje za procjenu površine uljne mrlje i količine ulja, na temelju koda iz sporazuma iz Bonna o pojavnosti ulja (BAOAC), podatke o spektralnom odzivu čiste i uljem onečišćene morske površine, rezultate hiperspektralne klasifikacije. Osim informacija prikupljenih zrakoplovnim multisenzorskim sustavom, u proces fuzije bile su uključene informacije dobivene od svemirskog sustava CleanSeaNet Europske agencije za pomorsku sigurnost – EMSA (u okviru velike pokusne aktivnosti – operativne vježbe u 2008.). Prednosti zrakoplovnih daljinskih istraživanja uljnih mrlja su pouzdana detekcija uljnih mrlja, precizno definiranje njezinog položaja i oblika u geografskim koordinatama, klasifikacija sadržaja uljne mrlje, mjerenje njezinih obilježja, procjenu količine ulja.
