The Relationship of Land Use Changes and Land Surface Temperature for Urban Area in Kuching, Sarawak

Abstract

Land surface temperature (LST) is used as an indicator for land temperature.Previous research demonstrates a strong correlation between urban growth andland surface temperature. The rising of land temperature will lead to urban heatisland if there are no preventative precautions done. Due to the area's rapidurbanisation, this study will focus on Kuching City. Matang Jaya, Tabuan Jaya,Satok, and Batu Kawa were chosen as case studies. These areas are rapidlydeveloping, with new townships and population growth. The Landsat 7 data setwas used as secondary data in this study. Spatial and thermal analysis wereperformed on the output using ERDAS software and ArcGIS. The analysesderived land use changes between 2005 and 2017, temperature statistics for landuse types, and LST retrieval for case studies. The result indicates that the landsurface temperature increased with the case studies' physical development.
