Peculiarities of using satellite data for determining the humidity of soil cover

The process of identifying and evaluating of the soil moisture indicator was improved by way of applying processing of multi-spectral aerospace images and conducting mathematical calculations on the data of spectral brightness of channels. Usage of the normalized index of NWI which is calculated on data from multi-spectral aerospace imaging on the basis of normalized difference of the spectral reflection in short-wave infrared spectral band is justified. Efficiency of this index in application to soil moisture evaluation for solving agrotechnical problems is proved.
