Reflectance ratios are widely used in the water quality retrieval algorithms, but they are not universally applicable and have to be tuned to the local conditions. In this study we present optical characteristics of the River Sava and assess two band ratio model for the prediction of concentrations of Chl-a from the hyperspectral data. We found that the best correlation was with the NIR-blue band...
Chlorophyll a (Chl-a) is an indicator of water quality, especially of eutrophic state. Remote sensing has been used to mapping Chl-a in lake, large river, estuary and ocean, due to its advantages such as to provide data logistically and economically. The aim of this paper was to use LandSat TM image and suitable algorithm to estimate and map Chl-a concentration in reservoir Dajingshan, an important...
