NDVI and Coastal Marine Waters Bullettins

The satellite remote sensing allows to investigate the territory with a spatial and temporal continuity that isn’t possible through a punctual analysis ashore. This peculiarity permits to realize, through the use of appropriate software, a multitemporal database of information, that can be used for a characterization of the investigated territory.
The remote sensing images allow to locate in a territory the presence of vegetation, whose conditions are monitored through the Vegetation Index. They find different application fields with various purposes like the determination of the vegetative vigour or the cultivations’ growth or their seasonal yield.
The NDVI (Normalized Difference Vegetation Index), in particular, is correlated to the vegetation’s state of health, understood as biomass and leaf area, and biochemical processes related to it (photosynthetic activity). The index values change typically from -1 (total vegetation absence) to +1 (total vegetation cover with multi leaf layer).
The remote sensing permits also to obtain information about waters’ state of health and consequently about their quality. The “Bulletin of Coastal Marine Waters” give us useful information in this sense. The marine variables examined for its realization are: Sea Surface Temperature (SST), turbidity, Total Suspended Solids (TSS) and Chlorophyll (Chl-a).
The realization of NDVI bulletins of Sicilian territory and Coastal Marine Waters of Sicily has been carried out thanks to the financing APQ “Young Protagonists of themselves and the territory” Action 7 – Youth and Job supplied by Department of Family, Social Policy and Labour of the Sicilian Region.
