Studying the peculiarities of agricultural lands with the use of digital relief models
The article highlights the stages of work during which the impact of individual terrain properties on arable farming was identified. The possibility of using digital elevation models (DEM) to identify those characteristics that can have a significant impact on such lands was studied. Findings have been made about the relationship between these features and the sites, and their place among other arable land features has been determined. The initial step was to select the baseline data for the area under study and obtain it in the form we needed. Here, techniques for automated DEM acquisition are being developed. At the next stage, individual terrain characteristics, complexity of their acquisition and ranking by importance for this methodology were considered and analyzed. At the final stage the analysis of agricultural lands, their connection with the relief and its characteristics was carried out, practical conclusions were drawn and recommendations were made based on them. It should be noted that the study area — the Vindrei River basin — is very illustrative for showing the advantages of the technology being developed. Its territory is occupied both by extensive agricultural land and forest areas. During the development of the methodology it was important to demonstrate the possibilities of using the technology in the field of nature management and improving economic efficiency of the area.
