Using space images for analysis of thermal anomalies in the city

Abstract

Paper analyzes thermal anomalies of Kazan city according to satellite images in thermal infrared range. Main goal of the study is to create maps of thermal anomalies in Kazan city, followed by recommendations to reduce impact of “heat island” phenomenon on the environment. Landsat satellite images for May and February were used as initial materials. Configuration of the “heat island” in different seasons of the year was studied. The study allowed us to identify areas in the city where differences in temperature and associated heat radiation were less intense, almost unchanged, or showed an increase. Thus, it was shown that within big industrial centers of a city separate foci of abnormally high temperatures are revealed. Classification of conditions according to the temperature level of city territories is developed. According to the results of the study, set of recommendations to reduce the negative consequences of the “heat island” impact on the urban ecosystem is proposed.
