Tullahoma_Heat_Risk_Index_2025

This heat risk layer was calculated using tree canopy coverage from classified 2023 NAIP imagery and enriched variables: 2024 population age 0–4, 2024 households with central air conditioning, 2022 households with income below the poverty level, and 2022 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 Tullahoma, TN.本热风险图层以2023年经分类处理的美国国家农业影像计划（National Agriculture Imagery Program, NAIP）影像提取的树冠覆盖率为基础，结合以下增强变量计算得到：2024年0-4岁人口数、2024年配备中央空调的家庭户数、2022年收入低于贫困线的家庭户数，以及2022年无车辆的自有住房家庭户数（数据源自美国社区调查（American Community Survey, ACS）五年期数据集）。针对田纳西州塔勒霍马市（Tullahoma, TN）构建的该要素类，通过融合2014-2024年多光谱陆地卫星（Landsat）影像反演的6-8月平均气温、树冠覆盖率及上述增强变量生成。
