SUMMARY:

Cities modify the local climate by creating a distinct condition defined as an urban climate but are also impacted locally by regional andglobal climate change. Therefore, it should be the focus of the urban architect's work. The transformations in urbanization patterns andtheir interactions with the urban climate lack data production to describe the urban fabric and capture different climate responses.Based on this aspect, the main objective of this research was to relate the spatial structure of local climatic zones (LCZs) of the urbanmacrozone with surface temperature, vegetation, and humidity indices in the climatic context of the Federal District. It was also aimedat disseminating spatialized information on urban heating in order to support urban architects and planners in making decisions aboutclimate-sensitive projects. For a view of the scale of the city, a method is proposed from Landsat 8 satellite imagery data to generatethe classification of local climatic zones following the WUDAPT method. Data from the same satellite will be used to characterizevegetation (EVI index) and surface temperature in hot-dry and hot-humid periods. The final integration of the spectral and spatial dataobtained was performed by zonal statistics in the QGis program. Statistical analyses of data distribution, correlation, and rank of postsalso evaluated whether the delineation of the LCZs resulted in different spectral values between the classes. Finally, an exploratoryanalysis of spatial data was performed to identify patterns and interdependence between variables of a data set. It was observed thatthe surface temperature is higher with spatially varied responses in urban classes, especially where there is less healthy vegetation andlower moisture content in the vegetation. The characteristics are heterogeneous and present regions with spatial dependence, beingmore evident in the rainy season. Evidence shows that the classification of LCZs can be used as a tool to monitor and promote ahierarchy of areas to be prioritized in the implementation of mitigation strategies for urban warming.
