This coverage represents the ignition points from YOSE fire history from 1930 through 2019. Where ignition points were not given on 1202 records, the ignition point was generated from the centroid of the fire history polygon. For fires that originated outside the park boundaries, some ignition locations are shown. The ignition location of record is kept internally by YOSE 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.

This coverage represents the YOSE fire history from 1930 through 2018. Original data was interpreted from historical fire records held at Yosemite National Park in the late 1980s. GRASS data was converted to Arc/Info coverage format when Yosemite migrated to Arc/Info in 1995. Some vector data was lost in conversion from GRASS. In those instances, polygons were vectorized from raster versions that remained in GRASS. Each year from 1995 - 2000, fires were input into Arc/Info by digitizing 1:24,000 USGS paper maps (7.5" series) or from Trimble GPS readings. Starting 2001, all larger fire perimeters were acquired through ground GPS or helicopter GPS reconnaissance. Small fire point locations were acquired through ground GPS or helicopter GPS and buffered to approximate fire size

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.

This is an updated version of the previously posted geospatial dataset of fire occurrence history within the Great Smoky Mountains National Park. Fire perimeters and point locations were taken directly from GPS field data when available, but this type of data is only available for the recent history during which GPS units were used by park officials. Otherwise, perimeters and points were digitized directly from the best sources available. In some cases these sources were hand-drawn maps, some were drawn on USGS topographic maps, and some were described through fire reporting narratives only. For the years 1942-present, the federal Wildland Fire Management Information (WFMI) list of fire occurrences for Great Smoky Mountains NP was consulted to provide fire locations and information. This list is updated annually by park fire officials and subsequently by the National Wildfire Coordination Group. It includes information related to the location, size, cost, fuels, and other pertinent information related to fires within the park's boundary. Additionally, park archives were consulted for a complete list of fire occurrences prior to 1942. Records for fires during the years of 1953-1959 have been lost or are otherwise not available. Perimeters corresponding to events from those years are generalized from a single list found in the park library. Some GIS data were taken from a 2003 fire mapping project by Lincoln Memorial University, and these fire perimeters were digitized directly from Mark Harmon's 1979 fire inventory. An accuracy assessment was performed on these and found the LMU data to be consistent with Harmon's maps, which were drawn by hand on USGS 7.5' quad maps.

This coverage represents the SEKI fire history from 1921 through 2023. A separate database exists that has attribute information based on the common relate item called "gisno". This was linked to the WFMI database but that was only updated through 2019. The 2020 and on additions were manually populated and attribute data pulled from Inform. As of 2022, there was still no integrated dataset. Some of the spatial data is blocky because it originated as a GRASS coverage with 30 meter resolution. Beginning in 1996, the fire history data has been digitally developed in Arc/Info. The resulting smooth line polygon shapefiles depict fires that are 1996 and later. A significant quality control process has increased the accuracy of attributes in the 2002 version and later.

This has now been linked to the WFMI database. 2020 data came from InForm and was manually merged with WFMI data from years prior. There was no integrated dataset of record at the time of publishing.

This vector polygon dataset represents fire history at Sequoia and Kings Canyon National Parks from 1921 through 2024. In the parks, fire history information is compiled from various sources including fire reports, drawn maps, remote sensing, and GPS. Some perimeter data prior to 1996 originated as GRASS coverages with 30 meter resolution. Beginning in 1996, spatial data was digitally developed in ArcGIS at varying scales (typically digitized from 15 minute or 7.5 minute topo quads). Spatial and attribute accuracy are greatly increased from year 2002 and later. Polygons now come from the GISS process for mapping wildfires (which are automatically associated with fire ignition points in InFORM but can be accessed other ways as well).
