2018, BRAZILIAN JOURNAL OF AGRICULTURE - Revista de Agricultura

Urban sprawl is the primary responsible for the current disposition of cities. And nowadays, all the importance that the conservation of the vegetal cover has is acknowledged, since it interferes with the quality of life, retains pollutant particles and the lack of it causes thermal discomfort. In this way the present work aims at analyzing the relationship between the presence of vegetation and the average temperature of the districts of the city of Piracicaba, in the state of São Paulo. RapidEye sensor image was used for mapping and quantification of vegetation and Landsat 8 for temperature quantification at 4 different times of the year. When it comes to vegetation, the city of Piracicaba has it in 40.44% of its territory. With the spatialization of the temperature, it is possible to observe its variation, presenting a thermal amplitude of 6.4° C in autumn. The areas that present the lowest rates of green areas stand with the highest temperatures, where the vertical constructions prevail, coupled with reduced tree cover.
