A unique visualization of the fire detections shows how the size of the pixel depends on the product and the scan angle. The confidence level and FRP are also used to illustrate the pixels. Hotspot fire detections and clear ground observations are used to drive the machine learning technique and draw fire perimeters at different times. </SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Suggested Usage:</SPAN></P><P><SPAN>Tracking fire perimeters and initialization and data assimilation for fire modeling.</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Satellite/Sensor:</SPAN></P><P><SPAN>L2 Active Fires data from MODIS and VIIRS satellites (MOD14, MYD14, and VNP14).</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Resolution:</SPAN></P><P><SPAN>750m to 1km</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">Credits:</SPAN></P><P><SPAN>NASA, NSF</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">ESRI REST Endpoint:</SPAN></P><P><SPAN>See URL section on the right side of page.</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-weight:bold;">WMS Endpoint:</SPAN></P><P><SPAN /></P></DIV></DIV></DIV> |
