To provide simple overall measures of similarity, the mean difference, the root mean square deviation, and the mean relative difference, between the OLI and ETM + data were derived as:(2)̅Δ̅=∑inviOLI−viETM+n(3)RMSD=∑inviOLI−viETM+2n(4)̅Δ̅*=∑inviOLI−viETM+0.5viO...
The RMSE (Root Mean Square Error) represents the square root of the ratio of the square of the deviation between the predicted value and the true value to the number of observations n (See Formula (3)). The accuracy of the KNDVI-SI remote sensing feature space monitoring index is the ...
