The main purpose of the study is to use remote sensing to investigate temporal changes in land surface temperature (LST) and Normalized Vegetation Index (NDVI) in Pune. Urbanization causes shifting urban geometry, which can substantially impact local microclimates and the planning of new urban settlements. As a result of urbanisation, there is planned as well as unplanned development and has shifts in land-use patterns. Pune has a hot semi-arid climate that borders a tropical wet and dry climate (Aw). Temperatures in the urban heat islands metropolitan area climb by several degrees when compared to the surrounding area. The study was carried out in Pune city for year 2001 and year 2021 to recognise land cover change and the heat island formed as a result of it. The imagery data from Landsat 7 (ETM+) and Landsat 8 (OLI/TIRS) was used and processed. The research was carried out to examine the relationship between creating Land Surface Temperature (LST) and Normalized Difference Vegetation Index (NDVI) maps. The study outcome for years 2001 and 2021, the acquired data revealed an increase in surface temperature of 2.91 degree Celsius. The study will help architects, planners and government officials to take adaptive and mitigate measures on the Urban Heat Island in due course of time.
