 This study investigated the effects of land use changes on land surface temperature, LST, in Duoc City, Iraq. Three Landsat images from 1990, 2000 and 2016 were analyzed using supervised classification to identify different land cover types. The results showed that the highest temperatures were found in barren lands and built up areas, ranging from 47°C, 50°C, 56°C in 1990, 2000 and 2016 respectively. Lower temperatures were observed in water bodies and forests, ranging from 25°C, 26°C, 29°C in 1990, 2000 and 2016 respectively. Additionally, the Normalized Difference Vegetation Index, NDVI, Normalized Difference Built-Up Index, NDVI, Normalized Difference Bearness Index, NDBAI, and Normalized Difference Water Index, NDWI, all correlated negatively with low temperatures, while NDVI and NDBAI correlated positively with high temperatures.
