Tornado Tracks (NWS Damage Assessment Toolkit, filtered for after 01/01/2026) - 164fe

Currently filtered for Storm Date is after 01/01/2026 Purpose: This is a feature layer of tornado swaths for the NWS Damage Assessment Toolkit. The National Weather Service (NWS) Damage Assessment Toolkit (DAT) has been utilized experimentally since 2009 to assess damage following tornadoes and convective wind events. The DAT is a GIS-based framework for collecting, storing, and analyzing damage survey data, utilizing the Enhanced Fujita (EF) scale for the classification of damage. Data collected from individual locations via mobile device are transmitted to a central geospatial database where they are quality controlled and analyzed to assign the official EF rating. In addition to the individual point, the data are analyzed to generate track centerlines and damage swaths. High resolution satellite imagery and radar data, through partnership with the NASA Short-term Prediction Research and Transition Center, are also available to aid in the analysis. The subsequent dataset is then made available through a web-based graphical interface and GIS services.

Data on this interface is collected during NWS Post-Event Damage Assessments. While the data has been quality controlled, it is still considered preliminary. Official statistics for severe weather events can be found in the Storm Data publication, available from the National Centers for Environmental Information (NCEI) at: https://www.ncdc.noaa.gov/IPS/sd/sd.html Questions regarding this data can be addressed to: [e-mail].当前已按风暴日期筛选为2026年1月1日之后的数据。 用途：本数据集为美国国家气象局（National Weather Service, NWS）灾害评估工具包（Damage Assessment Toolkit, DAT）的龙卷风破坏路径要素图层。 美国国家气象局灾害评估工具包（NWS DAT）自2009年起投入试验性应用，用于评估龙卷风及对流性风灾事件后的灾害损失。该工具包是一套基于地理信息系统（Geographic Information System, GIS）的框架，用于采集、存储与分析灾害勘测数据，并采用改进藤田（Enhanced Fujita, EF）等级量表对灾害破坏程度进行分类。 通过移动设备从各测点采集的数据将被传输至中央地理空间数据库，在库内完成质量控制与分析，以确定官方EF等级评级。除单个测点数据外，系统还会对数据进行分析以生成灾害路径中心线与破坏范围带。 此外，通过与美国国家航空航天局（National Aeronautics and Space Administration, NASA）短期预测研究与转型中心合作获取的高分辨率卫星影像与雷达数据，也可辅助灾害分析工作。最终生成的数据集将通过基于网页的图形界面与GIS服务对外提供访问。 以下为完整的REST服务地址：https://services.dat.noaa.gov/arcgis/rest/services/nws_damageassessmenttoolkit 地理平台官网地址：https://communities.geoplatform.gov/disasters/noaa-damage-assessment-toolkit-dat/ 更多信息 欢迎访问美国国家气象局灾害评估工具包。本界面所展示的数据均采集自美国国家气象局灾后灾害评估工作。尽管该数据已完成质量控制，但仍属于初步数据。强天气事件的官方统计数据可从美国国家环境信息中心（National Centers for Environmental Information, NCEI）发布的《风暴数据》出版物中获取，获取地址为：https://www.ncdc.noaa.gov/IPS/sd/sd.html 若对本数据集有任何疑问，请发送邮件至：[e-mail]。
