ANALYSIS OF CHANGES IN URBAN HEAT ISLANDS IN GORONTALO CITY USING THE LANDSAT TM8 IMAGERY

Abstract

An urban heat island is a condition where an area has a warmer temperature than the surrounding area in an urban area. Several articles indicate that the occurrence of urban heat islands is due to a decrease in the amount of vegetation and an increase in the number of built-up areas. This study aims to analyze changes in urban heat islands in Gorontalo City for five years based on urban spatial patterns. The research was conducted in the city of Gorontalo using Landsat TM8 imagery to measure the surface temperature at the study location. The method used is spatial analysis through Geographical Information Systems. The results showed that the highest surface temperature was in residential areas and the lowest was in the Green Open Space area
