摘要：Techniques of remote sensing for identification and analyses of the phenomenon of heat island are used in this study for the city of Goiânia-GO, in the year of 2001. The methodology proposed by Monteiro (1976), Urban Climate System, particularly the Thermodynamic Subsystem, are used to conduct a review of operations, performance and organization of the phenomenon of heat islands. The stages of work included the classification of land cover and the mapping of thermal camp of Goiânia, through the images of bands 3, 4, 5 and 6 (thermal band) of Landsat 7. Were considered as instruments of analysis: the urbanization, the geoecologic characteristics (topography) and the meteorology system (regional climate). The results show that the phenomenon of heat island is found in the municipality of Goiânia-GO, having differences of temperatures up to 10ºC between urban and rural area, being possible characterize certain anthropogenic uses (land covers classes) and altimetric intervals as potentiators of higher values of temperature. Key-words: Heat island. Remote sensing. Goiânia-GO.
