This service is provided by the National Interagency Fire Center.
This service includes perimeters for wildland fire incidents that meet the following criteria:
1) 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 2021
2) Is not "quarantined" in IRWIN due to potential conflicts with other records
3)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 2021 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.
