Satellite data from multiple time periods and spectrums showed how LULC dynamics affected LST in Bogra City between 1998 and 2023. Using Landsat data, LULC in Bogra was divided into five distinct sections. To examine spatiotemporal changes, NDVI, NDBI, NDWI, and NDBAI were constructed; LST was extracted from thermal bands and linear regression was used to link it with spectral indices. The results show that urban expansion and barren land exhibited positive correlations with LST, while vegetation cover and water bodies exhibited strong negative correlations. The classification outcomes confirm significant urban growth, accompanied by reduction of vegetated and agricultural areas. These findings highlight the impact of anthropogenic activities on local climate, emphasizing the necessity for sustainable land-use planning and green infrastructure development to mitigate rising urban heat effects.
