The development process over the past 50 years has had many positive and negative effects on urban communities around the world. One of the significant concerns is the constant increase in urban temperature called the urban heat island.

Among the issues that can be mentioned are community health, social welfare, urban infrastructure, energy demand and water resources, but it seems that this procedure is not one-sided, but these social, economic, etc This article intends to study the weather and images of LandSat-8 satellite and MODIS sensor to determine the exact location of thermal islands in the metropolis of Tehran, to overlap these images with GIS maps related to social and economic characteristics of the city. (Population density, quality of life, housing prices), to explain the formation of thermal islands as well as socio-economic developments. The results of this study show that areas ten and eleven and twelve of the metropolis of Tehran are among the main areas of the thermal islands of this city, which seems to be more evident due to the special social and economic characteristics of these areas, the distribution pattern of thermal islands.
