Hyperspectral tecniques for water quality monitoring: Application to the “Sacca di Goro” — Italy

The paper presents a comparison between an empirical algorithm and a physics based model for the assessment of water compound concentrations by remote sensing hyperspectral data. At the purpose a series of in situ measurements were carried out monthly, from June to October 2005, to spectrally characterize the water of the “Sacca di Goro” (Italy) at spatial (horizontal and vertical) and temporal (daily and seasonal) scales. The results obtained by the application of the two different methods to the in situ acquired data showed that an appreciable improvement is obtainable by considering the physical approach.
