WFIGS 2025 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 Wildfire (WF) or Prescribed Fire (RX) record Fire Discovery Date is in the year 2025 Is Valid and 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 2025 Wildland Fire Incident 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. Attributes and their definitions can be found below. More detail about the NWCG Wildland Fire Event Polygon standard can be found here.

The Organizational Assessment can be compared with the current Incident Management Organization and many other incident level data elements over the life of the fire. It may not always match the current Incident Management Organization value. The authority for producing the Organizational Assessment lies with the incident commander (NWCG PMS-210), thus, the Organizational Assessment can change independent of the published decision. attr_StratDecisionPublishDate The Decision Publish Date represents the date Agency Administrators published (approved) the Strategic Decision document.
