The process of studying the territories, water areas and the atmosphere based on the relationship between the properties of the decrypted objects and the nature of their reproduction in images from aerial and space images. The content and task of Decryption is to obtain a certain amount of quantitative and qualitative information on remote sensing data on the state, composition, structure, sizes, relationships and dynamics of processes, phenomena and objects using decryption features.

Abstract
The increasing anthropogenic impact on the soil and vegetation cover, insufficient effective land management, and climatic changes, the degradation process of soils and agrolandscapes is accelerated, and as a result, lands have low productivity, and agrolandscapes have poor environmental sustainability. In this regard, on the basis of modern digital technologies of remote sensing and geoinformation systems (GIS), an initial study in Karasai district of Almaty region in Kazakhstan was conducted, which is aimed at the timely identification areas of degradation agrolandscapes for the adoption of preventive measures. Based on spatial analysis of remote sensing data and field data, a soil-geomorphological map and landscape map of the region was compiled on a scale of 1:100000, which covers several taxonomic units: classes, subclasses, and types of landscapes. The territory of the Karasai region is a complex biogeosystem, as the analyzed territory consists of 52 types of landscape. This data allows a modern analysis of the agrolandscapes of the region.
