NIFC 2022 Wildfire Perimeters

The Wildland Fire Interagency Geospatial Services (WFIGS) Group provides authoritative geospatial data products under the interagency Wildland Fire Data Program. Hosted in the National Interagency Fire Center ArcGIS Online Organization (The NIFC Org), WFIGS provides both internal and public facing data, accessible in a variety of formats.This service includes perimeters for wildland fire incidents that meet the following criteria: Categorized in the IRWIN (Integrated Reporting of Wildland Fire Information) integration service as a valid Wildfire (WF), Prescribed Fire (RX), or Incident Complex (CX) record with a Fire Discovery Date in the year 2022Is not "quarantined" in IRWIN due to potential conflicts with other records Attribution of the source polygon is set to a Feature Access of Public, a Feature Status of Approved, and an Is Visible setting of Yes

Perimeters are not available for every incident. For a complete set of features that meet the same IRWIN criteria, see the 2022 Wildland Fire Locations to Date service.

No "fall-off" rules are applied to this service. 

Criteria were determined by an NWCG Geospatial Subcommittee task group.



Data are refreshed every 5 minutes. Changes in the perimeter source may take up to 15 minutes to display.

    Perimeters are pulled from multiple sources with rules in place to ensure the most current or most authoritative shape is used.Warning: Please refrain from repeatedly querying the service using a relative date range. This includes using the “(not) in the last” operators in a Web Map filter and

any reference to CURRENT_TIMESTAMP. This type of query puts undue load on the service and may render it temporarily unavailable.

Attributes and their definitions can be found below. More detail
