Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN STYLE="font-weight:bold;">Summary: </SPAN></P><P><SPAN>The Fire Event Data Suite, or FEDS, algorithm uses high resolution VIIRS observations to map fire perimeters, identify the active portion of fire fronts, and track the progression and attributes of individual fires every 12 hours. For individual fire events, FEDS contains information on the latest active fire detections, as well as the total fire event history in 12 hour increments. </SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Suggested Usage: </SPAN></P><P><SPAN>Perimeter data are helpful for understanding the time series progression of a fire event, as observed via the VIIRS sensor. Given the source data, the same considerations that must be taken for FIRMS active fire data are applicable here. All data are experimental and should always be verified with supplementary sources of information when available. </SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Date of Next Image:</SPAN></P><P><SPAN>Updates available at approximate 12-hour intervals.</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Satellite/Sensor:</SPAN></P><P><SPAN>Suomi NPP and NOAA-20 satellites carrying the VIIRS sensor. The FEDS algorithm uses the locations and sizes of each pixel to derive perimeter information and track individual fire events. </SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Resolution:</SPAN></P><P><SPAN>375m at nadir</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Credits: </SPAN></P><P><SPAN>NASA Earth Information System (EIS) </SPAN></P><P><SPAN>Doug Morton, Melanie Follette-Cook, Elijah Orland, Tempest McCabe (all GSFC), Yang Chen (UC Irvine) </SPAN></P><P><A href="https://www.nature.com:443/articles/s41597-022-01343-0" STYLE="text-decoration:underline;"><SPAN>Scientific Paper</SPAN></A></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Esri REST Endpoint:</SPAN></P><P><SPAN>See URL section on right side of page</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">WMS Endpoint:</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Data Download:</SPAN></P><P><A href="https://maps.disasters.nasa.gov:443/download/gis_products/event_specific/2023/hawaii_wildfires_202308/EIS_FEDS_Observations/" STYLE="text-decoration:underline;"><SPAN>https://maps.disasters.nasa.gov/download/gis_products/event_specific/2023/hawaii_wildfires_202308/EIS_FEDS_Observations/</SPAN></A></P></DIV></DIV></DIV>
