Possibility of Zhuhai-1 Hyperspectral Imagery for Monitoring Salinized Soil Moisture Content Using Fractional Order Differentially Optimized Spectral Indices

Abstract: The possibility of quantitative inversion of salinized soil moisture content (SMC) from Zhuhai-1 hyperspectral imagery and the application effect of fractional order differentially optimized spectral indices were discussed, which provided new research ideas for improving the accuracy of hyperspectral remote sensing inversion. The hyperspectral data from indoor and Zhuhai-1 remote sensing imagery were resampled to the same spectral scale. The soil hyperspectral data were processed by fractional order differenti… Show more

“…In this study, three indicators, R 2 , RMSE, and residual prediction deviation (RPD), were applied to measure the performance of the regression model. R 2 demonstrates the robustness of the model, RMSE characterizes the precision of the model, and RPD reflects the predictive power of the model [75]. Besides, Pearson correlation coefficient (R) was utilized to prefer the model independent variables.…”

“…When the absolute value of the correlation coefficient is greater than 0.6, the two sets of data are strongly correlated. The absolute value of the correlation coefficient was greater than 0.8, indicating a strong correlation between the two sets of data [42]. In order to further improve the accuracy of modeling, reduce the number of modeling parameters.…”

“…There are also data products available from satellites that are out of service, such as Earth Observing-1 (EO-1) and Environmental Satellite (Envisat) [ 33 ]. China mainly operates three major satellite systems for land, ocean, and meteorology [ 34 ], and the hyperspectral satellites that are in orbit and widely used include GaoFen-5 (GF-5) [ 35 , 36 , 37 , 38 ], ZiYuan-1 02D (ZY-1 02D) [ 39 ], HuanJing-1A (HJ-1A) [ 40 , 41 , 42 , 43 ], and Orbita Hyperspectral (OHS) [ 44 , 45 ]. However, few hyperspectral satellites have been utilized for the identification studies of bamboo species.…”
