Comparison of Spectral Classification Methods in Water Quality
Abstract
Today, water quality and water pollution can be detected using remote
sensing and its terrestrial components. Remote sensing does not only provide a
quick solution to detect water quality and pollution, but it could also be low
cost. Within the scope of the study, the water quality of the İmranlı area of
the Kızılırmak River, one of the most important water resources of the Sivas
region and the İmranlı dam on the river, was investigated by spectral
classification methods. Water samples were taken from various points on the
river and dam and their chemical oxygen demands were determined in the
laboratory. In addition, the reflectance values of the water samples taken by
the local spectral measurements were examined in order to use as end members
for spectral classification. CHRIS Proba is used as satellite image. Match filtering (MF), spectral angle mapping
(SAM) and spectral information divergence (SID) methods have been used as the spectral
classification methods and it has been examined which method gives better
results in determining water quality. According to the results, it is
understood that SAM method provides better classification accuracy than other
methods.
