Abstract
One approach is proposed for the application of high-resolution aerospace images in soil science. The process of soil salinization in the pilot area of the Kura-Araks lowland is investigated. For the first time, an analysis of spectral curves based on data from four channels of the AzerSky satellite and an extended range of wavelengths of the electromagnetic spectrum based on eight channel satellite WorldView2 is given for this territory. The analysis of spectral curves and the use of other methods (calculation of indices, filtration, the principal component method, classification) made it possible to more accurately separate soils with varying degrees of salinity and reveal features of the course of the spectral curves of soils and vegetation on areas saline to varying degrees.
