This vector point feature layer represents the ignition points from SEKI fire history from 1921 through 2024. Ignition locations for fires are typically mapped with GPS units or estimated on USGS Topo Quads by helicopter, field personnel, or fire lookouts. These locations are reported first locally (i.e. to dispatch) for operational response and then to national reporting systems. The locations in this dataset are imported from these various national reporting systems.

DI-1202 Individual Fire Reports

Historically, NPS fires were reported manually on DI-1202 Individual Fire Report Forms. Many locations in this dataset are from these DI-1202 records and their accuracy is variable. Where ignition points were not given on DI-1202 records, the ignition point was generated from the centroid of the fire history polygon.

Shared Applications Computer System (SACS)

Although the paper DI-1202 is the official fire record, many fire locations on DI-1202s were actually extracted from SACS. SACS was a computer system hosted by NIFC in Boise, Idaho for DOI agencies (NPS, FWS, and BIA) to electronically submit data from their DI-1202 forms. With this system, locations of fires were first recorded on paper, then uploaded, then annually downloaded to this dataset.

Wildland Fire Management Information System (WFMI)

WFMI replaced SACS as the primary fire reporting system in the 2000s for DOI because it tied into additional fire information systems. With the WFMI system, locations of fires were generated locally by fire personnel, uploaded into WFMI, and then annually downloaded into this dataset.

Integrated Reporting of Wildland Fire Information (IRWIN) and Interagency Fire Occurrence Reporting Modules (InFORM)

In 2018, NPS began the transition to InFORM, built on IRWIN. InFORM and IRWIN integrate and share data across disparate systems, reducing duplicative digital data entry. This system is tied to computer aided dispatch (CAD), so that fire locations are always up to date with whatever ground personnel have reported. With this system, locations of fires are automatically synced with IRWIN and then annually downloaded to this dataset.

Other Notes

For fires that originated outside the park boundaries, no ignition location is shown. The ignition location of record is kept internally by SEKI fire GIS staff due to the errors resulting from the SACS to WFMI conversion. These locations are the internal locations and not the locations shown on the 1202 report. WFMI was replaced by INFORM in 2020 but no official integrated dataset was complete by the time this dataset was processed. This data can be used for a variety of purposes including fire planning, operational applications, burned area recovery applications.
