As demonstrated by the phenomenon of the Urban Heat Island (Oke, 1973), human activities, changes in land use, progressive permeabilization with the consequent evapotranspiration reduction, make the city temperature values higher than in the countryside. This study aims to analyze the relationships between temperature and a series of urban parameters (urban density, green, materials, etc.) in order to take account of these aspects in the urban planning to mitigate urban climatic phenomenon. The research is so divided in two parallel tracks: the analysis of the physical structure of the city of Bari, for the study and the identification of the parameters above, and the thermal analysis of the same area using thermal bands of ASTER satellite imagery. From the initial results can be highlighted as the mutual influence of the parameters is rather complex and can’t be described with a simplified model, but it takes a multivariate analysis that allows to represent the interactions of the variables in an accurate manner.
