THE EFFECTIVENESS OF GIS TOOLS IN THE AGRICULTURAL LAND MONITORING AND MANAGEMENT SYSTEM

Abstract

The article evaluates the effectiveness of geoinformation tools in monitoring and managing agricultural lands using the example of the Abai region and the East Kazakhstan region. The topographic base, digital soil maps and data from the Sentinel-2 satellite are combined into a single geobase: true-color composites and the index of normalized vegetation difference (NDVI), as well as a thematic map of agricultural cover. The methodology includes the masking of atmospheric barriers, the creation of seasonal composites, regional NDVI statistics on land use classes and soil types, as well as criteria for the effectiveness of the process (accuracy, efficiency, labor intensity, interoperability). State maps and management repositories of agricultural landscapes have been obtained, defining the zones of agrostress and the differences between "arable land" and "pasture degradation". The scientific discovery consists in the practice-oriented integration of satellite indicators and the soil zone for updating digital soil maps. The practical importance lies in the reproducibility of updates and the availability of data for use in management.
