The article presents the possibilities of mapping dynamics of the normalized differential vegetation index (NDVI) onto the territory of the North Caucasian Federal District based on Russian satellite images of medium resolution. In the course of our work, the statistical weather data were processed and analyzed based on the results of long-term ground-based observations at some weather stations. The methods of using remote sensing data for mapping using GIS technologies were explored and NDVI index maps were compiled. Using remote sensing data and the calculated vegetation indices makes it possible to successfully map various processes and phenomena; the maps compiled in this way can be used to solve a wide range of scientific and practical problems.
The article discusses the changes in the NDVI on the territory of the Alexandrovsky and Novoselitsky municipal districts of the Stavropol Territory during the active vegetation period of 2020. The data source were Sentinel-2 thematic images, the spatial resolution of which is 10 m. The schematic maps reflecting the distribution of the NDVI by dates with minimal cloud cover in June-September 2020 have been compiled and analyzed. To explain the spatial and temporal pattern of changes in the areas occupied by different gradations of the NDVI, the data of the Aleksandrovsky weather station for 2020 (the course of temperature and precipitation during the year) were analyzed here as well. The use of remote sensing data and corresponding vegetation indices allows mapping various processes and phenomena in the GIS sphere, and the compiled maps can be used to solve a wide range of theoretical and practical tasks, including crop yields assessement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
