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.
