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)Has not been declared contained, controlled, nor outHas not had fire report records completed (certified)Is Valid and not "quarantined" in IRWIN due to potential conflicts with other recordsAttribution of the source polygon is set to a Feature Access of Public, a Feature Status of Approved, and an Is Visible setting of YesPerimeters are not available for every incident. For a complete set of features that meet the same IRWIN criteria, see the Current Wildland Fire Locations service."Fall-off" rules are used to ensure that stale records are not retained. Records are removed from this service under the following conditions:If the fire size is less than 10 acres (Size Class A or B) and fire information has not been updated in more than 3 daysFire size is between 10 and 100 acres (Size Class C) and fire information hasn't been updated in more than 8 daysFire size is larger than 100 acres (Size Class D-L) but fire information hasn't been updated in more than 14 days.Fires from previous calendar years are excluded.Fire size used in the fall off rules is from the IRWIN IncidentSize field.Fires that are no longer in the Current Wildland Fire Perimeter service will be displayed in the Wildland Fire Perimeters Year to Date and/or the 'Full History' 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.Fall-off rules are enforced hourly.Attributes and their definitions can be found below.

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_StratDecisionPublishDateThe Decision Publish Date represents the date Agency Administrators published (approved) the Strategic Decision document.
