Abstract:

Water quality parameters were retrieved for the Reservoir Shitoukoumen using Landsat-5 TM data acquired on August 29, 2007 supported by concurrent in-situ measurements. On the basis of cluster analysis (CA) and principle component analysis (PCA) of twenty water samples with seven variables, multiple regression algorithms were established and subsequently used to produce water quality spatial distribution maps over the entire geographic area.

Key words: remote sensing, water quality, in-situ, dissolved organic carbon, multiple regression
