Urban heat island (UHI) has been a detrimental problem over the last decades. Also, climate change has obtained more attention due to increased urbanization. Turkey is one of the countries experiencing a rapid urbanization which has resulted in significant UHI impacts on the regional climate and environment. This study was conducted in Osmaniye city, Turkey, where there is a need to determine the effects of land-use/land-cover changes (LUCC) on the UHI using Landsat images. The geospatial analyses were undertaken using USGS/NASA Enhanced Thematic Mapper Plus geospatial data from 2000 to 2018. The results showed that percent cover of urban areas significantly increased from 6.13 to 17.76%, broad-leaved forest cover decreased from 14.2 to 11.6%, road and rail network cover increased from 5.23 to 10.85%, and coniferous forest cover decreased from 15.85 to 9.02% between 2000 and 2018. During the process of urbanization from 2000 to 2018, most of the bare land cover was converted to agricultural lands and urbanized areas due to vegetative degradation, and industrial units cover increased from 7.76 to 9.53%. The land surface temperature was 35.57 degrees C for approximately 25% of the study area in 2000, while the same temperature was calculated for 76% of the study area in 2018. The results suggest that LUCC from vegetation to urbanized areas has significantly increased the land surface temperature. This implies that the application of remote sensing technique could help to design methods to mitigate UHI effects by estimating future land-use/land-cover change in urban areas.
