According to determining 5% deviation range limit value, the measured value of each spectral wavelength contrasted one by one, when on the whole piece curve of spectrum
When the point relative deviation on 5% spectral wavelength is had more than more than 5%, the spectroscopic data of this time measurement confirms invalid；When whole
When having the point relative deviation on the spectral wavelength less than 5% on the bar curve of spectrum more than 5%, spectral measurement correspondence ripple is rejected
Long spectral value, then the spectrum is preserved, and be mean quality spectrum by the spectral marker；When all of spectrum ripple of whole piece curve

Data atmospheric correction is compared or water colour parametric inversion modeling；When optimum spectrum is not enough, carried out from mean quality spectrum
Subsequent analysis；By the contrast of this curve of spectrum one by one spectral wavelength value one by one, accomplish more respective passage point-to-pointly
Spectroscopic data, so as to weed out the measured value of discrepant, discordance, it is to avoid the data uncertainty of single channel measurement is asked
Topic；
Step 5：Data storage, master control set (1) will be stored by the data checked.
6. method according to claim 5, it is characterised in that：The survey of the dual pathways water body apparent spectral described in step 3
