Last year Esri updated the wildfire live feed hosted in the Living Atlas for the United States. This service leverages the Integrated Reporting of Wildland-Fire Information (IRWIN) location database along with the polygon perimeters from the National Interagency Fire Center (NIFC). View the live feed here.
Since publishing, this layer has been viewed over 82 million times and was used extensively during the record setting 2020 fire season.
The ArcGIS Living Atlas and Disaster Response teams have updated this layer with additional incident age fields as well as changes to the cartography.
The new fields added to Current_Incidents point layer and Current_Perimeters polygon layer are Integer fields that calculate the ‘Days Since…’ the incident record was created and modified. These fields are computed when the data is updated, reflecting the current number of days since each record was last updated.
- CurrentDateAge: (Integer) Computed days since perimeter last modified.
- CreateDateAge: (Integer) Computed days since perimeter entry created.
- The point layer symbol has been reclassified so that the active incidents are now five classes based on acreage. This way viewers can more easily reference the symbol size to its actual acreage class in the legend.
- Prescribed Fires and Incident Complexes now have their own unique symbols differentiating them on the map. Colors used follow current fire industry standards.
- For situational awareness purposes incidents occurring within the last 24 hours are in a heavily saturated yellow so they figure most prominently on the map.
- Fire perimeters were also updated to reflect the new classification and colors to separate Wildfires and Prescribed Fires.
This live feed is updated every 15 minutes using the Aggregated Live Feed Methodology based on the following filters:
- Events modified in the last 7 days
- Events that are not given a Fire Out Date
- Incident Type Kind: Fires
- Incident Type Category: Prescribed Fire, Wildfire, Incident Complex
View only the data you need
There are many ways you can adjust this layer to display what you need. Let’s say for example you are only interested in showing where prescribed fires are located. The animation below walks you through the process of applying a filter to only view the category of ‘Prescribed Fires’ (RX). Apply this same process to other fields as needed to focus your map based on your needs.
