Implementation of complex methods of earth’s remote sensing data processing for studying carbonation processes of soils with artificial irrigation

Abstract

The article represents methodical researh of carbonation processes of agricultural lands based on Earth’s remote sensing data. The research is carried out on the territory of Svetloyarsk irrigationsystem located in Volgograd region. The article considered a set of methodical approaches for complex digital processing of multispectral space survey data and field results. The material on the deciphering features of carbonized lands is generalized and the relationship between the spectral brightness of pixels and the level of carbonation in the fields is established using scatter diagrams. Methods for collecting field data for complex processing together with high-resolution satellite images are determined. The test plots of soils are identified by the level of carbonation with their graphical display on cartographic schemes. The reliability of identifying zones of pixel display of carbonated agricultural lands was determined at the level of 75 %.
