| Zusammenfassung |
Information acquired and provided in Near Real Time is fundamental in
contributing to reduce the impact of different sea
pollution sources on the maritime environment. Optical data acquired by sensors aboard meteorological
satellites, thanks to their high temporal resolution as well as to their
delivery policy, can be profitably used for a Near Real Time sea monitoring,
provided that accurate and reliable methodologies for analysis and
investigation are designed, implemented and fully assessed.
In this paper, the results achieved by the application of an improved version of
RST (Robust Satellite Technique) to oil spill detection and
monitoring will be shown. In particular, thermal infrared data acquired by
the NOAA-AVHRR (National Oceanic and Atmospheric Administration-Advanced Very
High Resolution Radiometer) have been analyzed and a new RST-based change
detection index applied to the case of the oil spills that occurred off the Kuwait and
Saudi Arabian coasts in January 1991 and during the Lebanon War in July 2006.
The results obtained, even in comparison with those achieved by other AVHRR-based
techniques, confirm the unique performance of the proposed approach in
automatically detecting the presence of oil spill with a high level of reliability
and sensitivity. Moreover, the potential of the extension of the proposed
technique to sensors onboard geostationary satellites will be discussed within
the context of oil spill monitoring systems, integrating products generated by
high temporal (optical) and high spatial (radar) resolution satellite
systems. |
