The effect of building density on land surface temperature, (Case Study: Turikale District, Maros Regency)

Abstract

The amount of land built has increased over the years as the population increases. This results in a higher building density, such as in Turikale District, Maros Regency. Each object on the earth's surface has its distinctive temperature, such as the buildings. The heat of the earth's surface on certain location points will be captured by the image as an area that has a different surface temperature. The purpose of this study is to determine the temporal-spatial pattern of building density and surface temperature in Turikale Subdistrict, Maros Regency in 2013 and 2018 and is expected to be useful for Turikale District spatial planning and urban environment. Building density data and surface temperature are obtained from Landsat 8 Path 114 row 063 in 2018 and 2013. The data is processed using the Normalized Difference Built-up Index (NDBI) algorithm and Land Surface Temperature (LST) using ArcGIS. Furthermore, an analysis of differences in building density patterns with land surface temperature is analyzed spatially and temporally. The results of the study show that the spatial pattern of building density grows to be higher in density each year, especially in densely populated residential areas and near Jalan Daya-Maros, Turikale District. Temporal patterns of land surface temperatures show significant increases between 2013 and 2018.
