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.</font></p><div style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'>&nbsp;</div><div style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'>Here is the full REST service:&nbsp;<a style='color:rgb(0, 121, 193); font-family:inherit; text-decoration-line:none;' target='_blank' href='https://services.dat.noaa.gov/arcgis/rest/services/nws_damageassessmenttoolkit' rel='nofollow ugc noopener noreferrer'>https://services.dat.noaa.gov/arcgis/rest/services/nws_damageassessmenttoolkit</a></div></div><div style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'>Geoplatform website:&nbsp;<a style='font-family:&quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size:15px;' target='_blank' href='https://communities.geoplatform.gov/disasters/noaa-damage-assessment-toolkit-dat/' rel='nofollow ugc noopener noreferrer'>https://communities.geoplatform.gov/disasters/noaa-damage-assessment-toolkit-dat/</a></div><div>&nbsp;</div><div><strong>More Information</strong></div><p>Welcome to the National Weather Service Damage Assessment Toolkit.
