Improved multivariate modeling for soil organic matter content estimation using hyperspectral indexes and characteristic bands
Soil organic matter (SOM) is a key index of soil fertility. Calculating spectral index and screening characteristic band reduce redundancy information of hyperspectral data, and improve the accuracy of SOM prediction. This study aimed to compare the improvement of model accuracy by spectral index an...
