Soldatov (2011) the cluster analysis application provides the possibility to reduce
these risks. The clusters that are formed in the space of the spectral images are very
well separated. It enables to reduce these risks into the interval from 0.06 to 0.17.
The Adaptive Identi er is based on the employment of ESAIEP, ESECEZ and

SSHHI functions which are used for the solution of the speci

c problems arising

under the water quality diagnostics. The adaptive identi er allows the generation of
