The fast urbanization also changes the land cover, lowers the vegetation, and increases thermal stress in urban areas. This paper evaluates the spatial correlation among urban growth, loss of green cover, and surface temperature of land in Mysuru, Karnataka, in terms of multi-temporal Landsat 8 imagery and GIS analysis. Normalized Difference Vegetation Index (NDVI), Normalized Difference Built-up Index (NDBI), and Land Surface Temperature (LST) had been calculated with the aim to assess vegetation distribution, the extent of built-up, and urban heat island (UHI) patterns. The percentile-based thresholds were used to determine high built-up-high LST zones and loss areas of green cover and a ward-level environmental vulnerability assessment was performed. The findings indicate that there is a high spatial relationship between high population density in built-up areas, low vegetation, and high surface temperatures especially in central and fast growing wards. The research creates a strong, spatial explicit model of defining environmentally susceptible areas and upholds climate-sensitive urban development in Mysuru.
