Analyzing Urban Heat Island Intensity in Louisville, Kentucky Using Landsat Thermal Data

Urban Heat Islands (UHIs) pose a growing environmental challenge in densely built areas, where temperatures are significantly higher than in surrounding rural regions due to infrastructure and reduced vegetation. Louisville, Kentucky, is susceptible to UHI effects, impacting public health and increasing energy demands. This study leverages Landsat 8 satellite data to analyze the spatial distribution of UHI intensity within Louisville by examining Land Surface Temperature (LST) and vegetation density through the Normalized Difference Vegetation Index (NDVI). By mapping hotspots and correlating NDVI values with surface temperatures, the study aims to quantify the cooling effects of vegetation. The results will inform urban planning strategies by identifying priority areas for green space expansion, tree planting, and community-driven greening projects to mitigate UHI effects and a more sustainable urban landscape in Louisville.
