Wildfire Perimeters (NIFC)

This ArcGIS Online hosted feature service displays perimeters from the National Incident Feature Service (NIFS) that meet ALL of the following criteria: 

  • FeatureCategory = 'Wildfire Daily Fire Perimeter' 
  • IsVisible = 'Yes' 
  • FeatureAccess = 'Public' 
  • FeatureStatus = 'Approved'.  

This dataset is made up of current, active wildfires.  On a weekly basis, fires meeting specific criteria are removed from the source service. After removal, those perimeters can be found in the associated "Archived Wildfire Perimeters" service. Criteria include:
  • Perimeters are identified with an IRWIN ID that has non-null values in IRWIN for ContainmentDateTime, ControlDateTime, or FireOutDateTime
  • The most recent controlled/contained/fire out date is greater than 14 days old
  • No IRWIN ID
  • Last edit (based on DateCurrent) is greater than 30 days old
This hosted feature service is not "live", but is updated every 5 minutes to reflect changes to perimeters posted to the National Incident Feature Service. It is updated from operational data and may not reflect current conditions on the ground. For a better understanding of the workflows involved in mapping and sharing fire perimeter data, see the NWCG Geographic Information System Standard Operating Procedures On Incidents (GSTOP) and most recent addendums: https://www.nwcg.gov/publications/936.

To use this service from the Open Data site in a web map, click the APIs down arrow, copy the GeoService URL (remove the /query? statement) or just copy and paste this URL and add it to a web map (Add > Add Layer from Web): https://services3.arcgis.com/T4QMspbfLg3qTGWY/arcgis/rest/services/Public_Wildfire_Perimeters_View/FeatureServer

From within ArcGIS Online, open this feature service in a new web map by clicking Open in Map Viewer. 

Once this service has been added to a web map, the features can be filtered by incident name, GACC, Create Date, or Current Date, keeping in mind that not all perimeters are fully attributed. Not all data are editable through this service and delete is disabled. To delete features, open in ArcGIS Pro or ArcMap.

If your perimeter is not found in the Current Wildfire Perimeters, check in the Archived dataset: https://nifc.maps.arcgis.com/home/item.html?id=090a23c0470d4ef9a27142ee9b200023
