The paper describes a number of simplified methods of mapping of the urban environment surface temperature in order to study the structure of the urban heat island. It is very important to take into account the climatic and environmental variables of the territories when planning modern cities and settlements. To solve such problems, methods of remote sensing data are used increasingly. The study of multispectral satellite images provides more information about the characteristics of objects on the earth’s surface, as well as data on the distribution of various types of land use. Maps of the earth’s surface temperature (LST) can be used for studying the urban microclimate and localization of temperature anomalies of the city, as well as for urban planning tasks. The article considers the operation of processing a series of satellite images of urban areas for the summer period, followed by the study of temporary changes in the temperature portrait of the city. The paper considers the use of semi-automatic methods for obtaining satellite images in the thermal field, as well as a separate study of images in the near-infrared field to search for bright point sources of heat. Radiometric and atmospheric correction was performed on satellite data using the QGIS package and the Semiautomatic Classification Plugin extension. Based on the results of the study, thermal anomalies were localized in the city, and the boundaries of the heat footprint of new neighborhoods were determined.
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.
