Cleveland_Heat_Risk_Index_2026

This heat risk layer was calculated using tree canopy coverage from classified 2023 NAIP imagery and enriched variables: 2025 population age 0–4, 2025 households with central air conditioning, 2023 households with income below the poverty level, and 2023 homeowners without a vehicle (ACS 5-Year). Average June–August temperatures from Multispectral Landsat imagery (2014–2024), combined with tree canopy and enriched variables, were used to formulate this feature class for Cleveland, TN.该热风险图层的计算基于经分类处理的2023年美国农业影像计划（National Agriculture Imagery Program, NAIP）影像提取的树冠覆盖率，以及多组扩充变量：2025年0-4岁人口、2025年配备中央空调的家庭户数、2023年贫困线以下家庭户数，以及2023年无车辆的自有住房户数据（数据来源为美国社区调查5年估计数据集（American Community Survey 5-Year, ACS 5-Year））。本研究结合2014-2024年多光谱陆地卫星（Landsat）影像获取的6-8月平均气温，与上述树冠覆盖率及扩充变量，为田纳西州克利夫兰市构建了该特征要素类。
