WFIGS

Authoritative incident-level wildfire records maintained by U.S. interagency fire management systems, providing official information on real wildfire events across the United States.


Overview

WFIGS (Wildland Fire Incident Geospatial Services) is an interagency system that aggregates and distributes geospatial information on active and historical wildland fire incidents. Each record represents an officially reported wildfire event, rather than a satellite-detected hotspot.

WFIGS is commonly treated as an authoritative source of wildfire ground truth and is widely used to validate satellite-based fire detections and to label wildfire occurrence in modeling pipelines.


Data Characteristics

  • Spatial coverage: United States

  • Temporal coverage: Historical and ongoing wildfire incidents

  • Temporal resolution: Event-based (ignition, containment, and status updates)

  • Data structure: Incident-level event records (point or polygon geometries)

  • Data format: GIS services, GeoJSON, Shapefile

  • Coordinate system: Geographic and projected systems (service-dependent)


Variables

Typical WFIGS records include:

  • Incident name and unique incident identifier

  • Ignition date, discovery date, and containment status

  • Incident location (point or perimeter geometry)

  • Fire size, cause, and management status

  • Associated agency and reporting metadata


Typical Use Cases

  • Ground-truth labeling of wildfire occurrence

  • Validation of satellite-based fire detection products (e.g., FIRMS, GOES)

  • Analysis of wildfire ignition timing and spatial patterns

  • Integration with meteorological and fuel datasets for fire modeling studies


Access

WFIGS data are publicly accessible through U.S. interagency geospatial portals:
