Remote sensing, ecological water quality modelling and in situ measurements: A case study in shallow lakes

The application of high spectral and spatial resolution airborne remote sensing has developed to an almost operational level. This paper investigates the role of remote sensing especially coupled to the two other available water quality assessment tools: in situ measurements and eco logical water quality modelling data. A case study is presented for three shallow lakes varying in trophic level. Based upon a similarity index it is demonstrated that remote sensing provides valuable additional information for chlorophyll-a, seston dry weight and Secchi depth measurements, as compared to the two other water quality assessment tools.
