The relation between heat islands and the use and occupation of the soil in small urban centers through remote sensing

Abstract

Every day urban centers suffer from rising temperatures. Faced with global warming, degradation of these environments, pose risks to the health of the population, from the thermal discomfort to the occurrence of diseases caused by heat. Due to the urbanization process, this change in the landscape favors an occurrence of the phenomenon of the urban heat island (ICU), urban areas with temperatures higher than its surrounding rural areas. This phenomenon is reality not in large municipalities, but also occurs in small cities. The objective of this work was to analyze the occurrence of ICU in Ilha Solteira-SP, was studied through the use of remote sensing data, aiming to associate a surface temperature with different classes of land-use and land-cover. For a purpose of this work, a satellite image captured in the infrared region (TIRS/Landsat-8) were used as land use and occupation classes in the areas of higher temperatures, based on Images of high spatial resolution, in the satellite Pleiades. Given that the different classes of land use and occupation directly influence the surface temperature, observing an asphalt paving and ceramic roof as higher temperature values, in ICU areas in small cities.
