Resumo: The phenomenon called Heat Islands began to be noticed after the 19th century due to the great changes in the interactions of man with the surface. Studies related to climatology with the geotechnological advance were improved, which allows the analysis of different areas through the use of different methods. Thus, the objective of this study is to identify urban heat islands through remote sensing techniques, in different locations in the state of Santa Catarina: Joinville, Criciúma and Lages. For a better understanding of the urban surfaces of these cities, the following radiometric indexes were used: Normalized Density Vegetation Index (NDVI), Normalized Difference Built-up Index (NDBI) and Built-up Index (BU), in addition to Surface Temperature. Through the analysis of the results obtained, it was identified that heat islands are formed in areas that present high values ​​of BU and reduced values ​​of NDVI. The islands formed in Joinville and Criciúma occurred in a similar way, in the central portion of the cities due to the high density of urban elements, while in the city of Lages, the phenomenon was also concentrated in fragments of exposed soil, far from the urban area, due to the predominance of agriculture and forestry.

Los estudios relacionados con la climatología fueron perfeccionados con el avance geotecnológico, lo que posibilita el análisis de diversas áreas a través del uso de métodos variados. De esta forma, el objetivo de este estudio consiste en la identificación de islas de calor urbanas por medio de técnicas de percepción remota en diferentes localidades del estado catarinense: Joinville, Criciúma y Lages. Para una mejor comprensión de las superficies urbanas de estas ciudades, se utilizaron los siguientes índices radiométricos: Normalized Density Vegetation Index (NDVI), Normalized Difference Built-up Index (NDBI) y Built-up Index (BU), más allá de la Temperatura de la Superfície. A través del análisis de los resultados obtenidos, se identificó que las islas de calor se forman en áreas que presentan valores elevados de BU y reducidos de NDVI. Las islas formadas en Joinville y Criciúma ocurrieron de forma semejante en la porción central de las ciudades debido a la elevada densidad de elementos urbanísticos, mientras que en la ciudad de Lages, el fenómeno también se concentró en fragmentos de suelo expuesto, alejadas de la malla urbana, debido al predominio de agricultura y silvicultura.O fenômeno denominado Ilhas de Calor começou a ser percebido após o século XIX devido às grandes mudanças nas interações do homem com a superfície.
