Remote Assessment of Spectral Reflectance of the Surface of Drained Peat Soils of Polesye on the Basis of Satellite Images of Medium Spatial Resolution

摘要

The dependence of the spectral reflectance (averaged over an area of approximately 0.023 ha) of peat and degraded peat soils of Polesye on the soil organic carbon content has been investigated under actual field conditions for the first time. The dependence is approximated by exponential and power functions, and the confidence intervals are explicitly calculated for each parameter of the approximating functions. The parameter values for the exponential function appear better validated than the parameter values for the power function, since the corresponding confidence intervals for the former are much narrower. The values of AIC and BIC information criteria show that the power model gives a better description of experimental data for bands 1 and 2, and the exponential model gives a better description for the 3N band of the ASTER spectroradiometer.
