Prospección de isla de calor urbana mediante firmas espectrales de calor en la ciudad de Bogotá D.C. en el periodo 1985-2022

Abstract

The urban heat island phenomenon has been studied in large cities of the world because it affects the climate, generating an increase in the effects of climate change, due to the increase of the urban area by anthropogenic processes in recent decades. This study was developed over the territory of Bogota, and its objective was to carry out a thermal prospection with spectral heat signatures between 1985 and 2022. For the analysis, Landsat satellite images provided by the U.S. Geological Survey were taken; they were processed by remote sensing techniques in two geographic information systems to compare the results obtained. It was possible to conclude that the spatiotemporal variation of urban heat islands in Bogota has increased steadily in different parts of the city during the time analyzed.
