Identification of the impact of vegetation cover changes and the development of urban areas on Urban Heat Island using GIS and remote sensing: A case studies of Sleman regency, Province of Yogyakarta

Abstract

Abstract The phenomenon of urban area development both physically and socially as the center of government in Sleman can indirectly cause an impact on the atmosphere. One of the impacts of the atmospheric change, the urban heat island, which is influenced by the physical and social development activities, is expanding. The research focuses on the study of surface urban heat island (SUHI) aimed at knowing the spatial distribution of the UHI intensity in Sleman Regency. The methods used in this research are the integration of remote sensing techniques and geographic information systems (GIS) using thermal bands of Landsat 8 OLI/TIRS and image statistical analysis using Buffer Boundary Analysis to identify the potential occurrence of UHI in Sleman. The result of the processing shows the potential of high-intensity urban heat island in Depok subdistrict, Ngemplak subdistrict, Kalasan subdistrict, and part of Mlati subdistrict with the varying intensity of UHI. The highest UHI intensity is around the district of Depok and Mlati with an intensity of 2,001 - 6,000 °c during the period from 2014 to 2019.
