Application of digital technologies to determine the properties of vegetation cover in agriculture

Abstract

At present, the use of digital technologies is becoming increasingly relevant in all fields of anthropogenic activity. In agriculture, an important area of digitalization is precision farming. In this case, the method of analyzing remote sensing data in geoinformation systems is of great importance; it enables identifying various parameters of agricultural crops (indices of vegetation, moisture availability, etc.) at processing. Therefore, it is important to develop a computer technology for manipulating the mentioned information and creating digital maps and models of the territory based on it. This requires high-quality work at the available satellite imagery materials. The author considers the course of determining the vegetation cover water indices in the ENVI software package using satellite images of the Landsat 7–9 survey systems. Based on the results of the calculation, digital 2D maps of the object under study were compiled, a GIS project (database) was developed, and a 3D elevation model was created. The obtained materials are intended for the analysis of natural and anthropogenic features, as well as for assessing the moisture content of the study object’s territory vegetation cover.
