LAUSR

The autors present the results of studying and mapping long-term irrigated soils using remote information from the satellite Ladsat-8 on the example of an irrigated area of the south of Russia (Svetloyarsky irrigation system, Volgograd region). Natural features and history of developing the area under study are considered, the results of field research and visual analysis of remote information are given; it enabled interpreting features of irrigated soils and the nature of using agricultural fields. Basing on the developed characteristics, a remote image was classified. The classification process was carried out in two stages, with a preliminary preparation of the image. At the first stage, agricultural use of fields was classified, at the second (using the CART algorithm “decision trees”) – the allocation of irrigated soils within each field. Basing on the classification results, a map of irrigated soils was created, taking into account their agricultural development.
