Urban Heat Island Characterization and Isotherm Mapping Using Geo-Informatics Technology in Ahmedabad City, Gujarat State, India

A study on Ahmedabad, India, revealed significant urban heat island (UHI) effects, with surface temperatures in industrial and dense urban areas rising 4–5°C above suburban levels. The research used satellite-based remote sensing data from Landsat ETM band-6 combined with in-situ measurements to map thermal hotspots. Findings highlighted severe temperature disparities linked to urbanization, industrial emissions, and poor planning, underscoring the need for sustainable interventions to mitigate climate impacts on air quality and public health.
