Abstract Urbanization refers to growth in the physical area of the urban settlements as a result of the movement of population from rural to urban areas. Bengaluru is one of the fastest growing metropolitan cities in India, which showed a massive increase in population between 2011 and 2021 (48% increase). This study focuses on the relation of LST with NDVI, NDBI and DEM in Bengaluru urban district using geospatial technologies. The correlation of LST with NDVI, NDBI and DEM were analyzed by using scatter plot. The results were indicating that LST has negative correlation with NDVI (R= -0.38) and positive correlation with NDBI (R = 0.5), whereas with DEM was no relationship even though variation in elevation. NDVI and NDBI relationship was found to be negative (R =-0.21). The findings of the study conclude that urban area has to tackle the negative impacts of temperature due to rapid urbanization and decrease in vegetation or green spaces. Urbanization is inevitable as long as there exists an economic development. Therefore, monitoring of land cover changes would help in better planning for the future. Urban green spaces need to be increased to mitigate the effect of temperature due to urbanization and other factors. Protection of urban water bodies also helps in mitigation. Sustainable development goals which specify on sustainable cities can be implemented with the help of Geospatial technologies to be focused on built-up area and urban planning. Creating awareness at individual level is also a part of mitigation
