| Abstract |
Recent intensification of heatwaves and urban heat island (UHI) phenomena in the Seoul metropolitan area underscores rising urban temperatures. This study evaluates the impacts of urban spatial components and greenery type on land surface temperatures at a microscale, focusing on the Incheon Inner Harbor, using ultra-high-resolution thermal imagery obtained by Unmanned Aerial Vehicle (UAV). Results indicated impervious areas experienced temperatures up to 42?45°C, while forested areas showed significant cooling effects, including spatial spillover to adjacent regions; however, green space cooling was limited in high-density urban areas and proximity to water alone was insufficient when impervious surfaces dominated, highlighting the need for integrated planning linking waterfronts and green spaces. This study contributes by employing UAV-based thermal data to spatially quantify interactions among vegetation types, urban density, and waterfront conditions, advancing urban heat mitigation strategies. |
