Description
This ArcGIS Online hosted feature service displays perimeters from the National Incident Feature Service (NIFS) that meet ALL of the following criteria:
FeatureCategory = 'Wildfire Daily Fire Perimeter'
IsVisible = 'Yes'
FeatureAccess = 'Public'
FeatureStatus = 'Approved'.

This dataset is made up of current, active wildfires. On a weekly basis, fires meeting specific criteria are removed from the source service. After removal, those perimeters can be found in the associated "Archived Wildfire Perimeters" service. Criteria include:
Perimeters are identified with an IRWIN ID that has non-null values in IRWIN for ContainmentDateTime, ControlDateTime, or FireOutDateTime
The most recent controlled/contained/fire out date is greater than 14 days old
No IRWIN ID
Last edit (based on DateCurrent) is greater than 30 days old
This hosted feature service is not "live", but is updated every 5 minutes to reflect changes to perimeters posted to the National Incident Feature Service. It is updated from operational data and may not reflect current conditions on the ground. For a better understanding of the workflows involved in mapping and sharing fire perimeter data, see the NWCG Geographic Information System Standard Operating Procedures On Incidents (GSTOP) and most recent addendums: https://www.nwcg.gov/publications/936.

To use this service from the Open Data site in a web map, click the APIs down arrow, copy the GeoService URL (remove the /query? statement) or just copy and paste this URL and add it to a web map (Add > Add Layer from Web): https://services3.arcgis.com/T4QMspbfLg3qTGWY/arcgis/rest/services/Public_Wildfire_Perimeters_View/FeatureServer

From within ArcGIS Online, open this feature service in a new web map by clicking Open in Map Viewer.

Once this service has been added to a web map, the features can be filtered by incident name, GACC, Create Date, or Current Date, keeping in mind that not all perimeters are fully attributed. Not all data are editable through this service and delete is disabled. To delete features, open in ArcGIS Pro or ArcMap.

Description

This data set is part of an ongoing project to consolidate interagency fire perimeter data. Currently only certified perimeters and new perimeters captured starting in 2021 are included.

A process for loading additional perimeters is being evaluated.

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)
Is Valid and not "quarantined" in IRWIN due to potential conflicts with other records
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. This data set is an ongoing project with the end goal of providing a national interagency fire history feature service of best-available perimeters.

No "fall-off" rules are applied to this service.

The date range for this service will extend from present day back indefinitely. Data prior to 2021 will be incomplete and incorporated as an ongoing project.

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.

Warning: Please refrain from repeatedly querying the service using a relative date range. This includes using the “(not) in the last” operators in a Web Map filter and any reference to CURRENT_TIMESTAMP. This type of query puts undue load on the service and may render it temporarily unavailable.

Description
The California Department of Forestry and Fire Protection's Fire and Resource Assessment Program (FRAP) annually maintains and distributes an historical wildland fire perimeter dataset from across public and private lands in California. The GIS data is developed with the cooperation of the United States Forest Service Region 5, the Bureau of Land Management, California State Parks, National Park Service and the United States Fish and Wildlife Service and is released in the spring with added data from the previous calendar year. Although the dataset represents the most complete digital record of fire perimeters in California, it is still incomplete, and users should be cautious when drawing conclusions based on the data.
This data should be used carefully for statistical analysis and reporting due to missing perimeters (see Use Limitation in metadata). Some fires are missing because historical records were lost or damaged, were too small for the minimum cutoffs, had inadequate documentation or have not yet been incorporated into the database. Other errors with the fire perimeter database include duplicate fires and over-generalization. Additionally, over-generalization, particularly with large old fires, may show unburned "islands" within the final perimeter as burned. Users of the fire perimeter database must exercise caution in application of the data. Careful use of the fire perimeter database will prevent users from drawing inaccurate or erroneous conclusions from the data. This data is updated annually in the spring with fire perimeters from the previous fire season. This dataset may differ in California compared to that available from the National Interagency Fire Center (NIFC) due to different requirements between the two datasets. The data covers fires back to 1878. As of May 2025, it represents fire24_1.

Please help improve this dataset by filling out this survey with feedback:
Historic Fire Perimeter Dataset Feedback (arcgis.com)

Current criteria for data collection are as follows:
CAL FIRE (including contract counties) submit perimeters ≥10 acres in timber, ≥50 acres in brush, or ≥300 acres in grass, and/or ≥3 impacted residential or commercial structures, and/or caused ≥1 fatality.
All cooperating agencies submit perimeters ≥10 acres.

Version update:
Firep24_1 was released in April 2025. Five hundred forty-eight fires from the 2024 fire season were added to the database (2 from BIA, 56 from BLM, 197 from CAL FIRE, 193 from Contract Counties, 27 from LRA, 8 from NPS, 55 from USFS and 8 from USFW). Six perimeters were added from the 2025 fire season (as a special case due to an unusual January fire siege). Five duplicate fires were removed, and the 2023 Sage was replaced with a more accurate perimeter. There were 900 perimeters that received updated attribution (705 removed “FIRE” from the end of Fire Name field and 148 replaced Complex IRWIN ID with Complex local incident number for COMPLEX_ID field). The following fires were identified as meeting our collection criteria but are not included in this version and will hopefully be added in a future update: Addie (2024-CACND-002119), Alpaugh (2024-CACND-001715), South (2024-CATIA-001375). One perimeter is missing containment date that will be updated in the next release.
Cross checking CALFIRS reporting for new CAL FIRE submissions to ensure accuracy with cause class was added to the compilation process. The cause class domain description for “Powerline” was updated to “Electrical Power” to be more inclusive of cause reports.

Includes separate layers filtered by criteria as follows:
California Fire Perimeters (All): Unfiltered. The entire collection of wildfire perimeters in the database. It is scale dependent and starts displaying at the country level scale.
Recent Large Fire Perimeters (≥5000 acres): Filtered for wildfires greater or equal to 5,000 acres for the last 5 years of fires (2020-January 2025), symbolized with color by year and is scale dependent and starts displaying at the country level scale. Year-only labels for recent large fires.
California Fire Perimeters (1950+): Filtered for wildfires that started in 1950-January 2025. Symbolized by decade, and display starting at country level scale.

Detailed metadata is included in the following documents:

Description
This map provides a number of layers from external fire agencies and organizations that provide consistently updated map layers regarding the location and status of active and past wildfires managed by CalFire as well as federal agencies. In addition, a NOAA weather warnings layer is included to get perspective on weather conditions that may affect the behavior of active fires. And, there is also a 2013 wildland fire potential map included in the table of contents. Please turn the layers on and off and explore the various information available in the map. This list includes all of the data sources for the map: Wildfire_Activity - Active perimeter:The Geospatial Multi-Agency Coordination Group (GeoMAC) is an internet-based mapping tool originally designed for fire managers to access online maps of current wildland fire locations and perimeters in the continental United States and Alaska. Perimeters are submitted to GeoMAC by the incident commands via FTP and web sites for downloading. This file contains all wildland fire perimeters that were submitted to GeoMAC by the incidents for the current year. The projection is geographic and the datum is NAD83. Last updated February 27, 2013, SPW. For more metadata see here CalFireData - Perimeters:Data originates from CalFire; however, metadata is not available. http://services.arcgis.com/QJfoC7c7Z2icolha/arcgis/rest/services/CalFireData/FeatureServer/1WildlandFire - Fire Location:Wildlandfire.com(www.wildlandfire.com) invites you to view and interact with a continuously updated map of current U.S. wildfire locations, fire potential areas, meteorological observations and radar imagery. These real-time layers provide insight into where a fire is located, its intensity and the localized weather patterns. Information from wildlandfire.com is professionally sourced fire intel from the boots on the ground, eyes in the sky, and ears on the radio. Chances are that information will come here first before anywhere else.

As the user interacts with the map more information becomes available. Other available tools such as measuring distance or getting a view of the terrain are available to help in assessing fire danger. We encourage you to turn on and off layers that suit your viewing preferences. The Weather Observation (Radar) and Fire Potential layers are initially turned off. Please find an area and view them as you interact with the map. The US Wildfire Locations layer displays large active fire incidents entered into the National Interagency Fire Center (NIFC) database by local emergency response groups. This layer is generated and maintained as part of the Geospatial Multi-Agency Coordination Group (GeoMAC) application, and also accessed by Natural Hazards Support System (NHSS).

Wildland Fire Potential layer was provided by the USFS and indicates zones of high, medium and low fire potential. Potential Fire

The Active Fire Perimeters layer is a product of Geospatial Multi-Agency Coordination (GeoMAC). Near real-time information for fire perimeter data is updated daily from incident sources, GPS data, infrared (IR) imagery such as fixed wing and satellite platforms.

The Federal Emergency Management Agency (FEMA) layer is created by FEMA and provides information regarding fire relief shelters locations, current status (open or closed) and number of occupancy. This near real-time layer is updated daily from FEMA Shelters.

The Moderate Resolution Spectroradiometer (MODIS thermal) layer is created from the MODIS satellite detection system and indicates hot spots that could be future fire locations identified in the last 24 hour period. Data source is the EOSDIS website hosted by NASA.

The Current Wind Conditions layer is created from hourly METAR/TAF data provided from NOAA. This layer uses arrow vectors and wind speeds to provide real-time wind flow dynamics.

Radar (Weather Observation) and weather (Red Flag Warnings) are both continuous real-time layers provided by NOAA. The weather observations layer provides high temperatures, surface pressure and wind barbs along with radar return. The weather warning layer provides an array of warnings that are available with pop-up windows. Weather_Warnings_Watches_Advisories_Statements - NOAA Weather Warnings, Watches, Advisories, and Statements:FROM NOAATitle: weather warnings, watches, advisories, and statements Author: The Yeti Team Comments: Weather Watches, Warnings, Advisories, and Statements are products of the National Weather Service (NWS).We automatically check these products for updates every 5 minutes from the NWS Public Alerts.

Category: Live Feeds Keywords: Esri, NOAABoth MODIS Datasets originate from the GeoMAC group, see below: geomac_dyn - MODIS Thermal Satellite:MODIS_Thermal - MODIS Thermal (Last 24 hours):In order to give fire managers near real-time information, fire perimeter data is updated daily based upon input from incident intelligence sources, GPS data, infrared (IR) imagery from fixed wing and satellite platforms. The GeoMAC web site allows users in remote locations to manipulate map information displays, zoom in and out to display fire information at various scales and detail, and print hard copy maps for use in fire information and media briefings, dispatch offices and coordination centers. The fire maps also have relational databases in which the user can display information on individual fires such as name of the fire, current acreage and other fire status information.See the Help page for more specific information.SNC - Sierra Nevada Conservancy:The Sierra Nevada Conservancy (SNC) is a California state agency created by bi-partisan legislation (AB 2600) and signed into law in 2004. The SNC was created with the understanding that the environmental, economic and social well-being of the Sierra Nevada and its communities are closely linked and that the Region and the State of California would benefit from an organization providing a strategic direction. The SNC Region, made up of all or part of 22 counties covering over 25 million acres, is one of the most significant natural and biologically diverse regions in the world. The Sierra Nevada constitutes about 25 percent of California’s land area and is the state’s principal watershed, supplying more than 60 percent of the developed water supply to residents, agriculture, and other businesses/industries across the state.Additional CalFire Layers: California Fire Perimeters - fire history:California Fire Perimeters Grouped By Year:CalFire KML Feed:CAL FIRE, USDA Forest Service Region 5, BLM, NPS, Contract Counties and other agencies jointly maintain a comprehensive fire perimeter GIS layer for public and private lands throughout the state. The data covers fires back to 1878. For the National Park Service, Bureau of Land Management, and US Forest Service, fires of 10 acres and greater are reported. For CAL FIRE, timber fires greater than 10 acres, brush fires fires greater than 50 acres, grass fires greater than 300 acres, and fires that destroy three or more residential dwellings or commercial structures are reported. Copyright Text: CAL FIRE recognizes the various federal, state, and local agencies that have contributed to this dataset, including USDA Forest Service Region 5, BLM, National Park Service, and numerous local agencies.WLFP_2013-Wildland Fire Potential 2013:For more information and access to download the GIS data, please see the Fire, Fuel, and Smoke Science Program website. The wildland fire potential (WFP) map is a raster geospatial product produced by the USDA Forest Service, Fire Modeling Institute that is intended to be used in analyses of wildfire risk or hazardous fuels prioritization at large landscapes (100s of square miles) up through regional or national scales. The specific objective of the 2012 WFP map is to depict the relative potential for wildfire that would be difficult for suppression resources to contain, based on past fire occurrence, 2008 fuels data from LANDFIRE, and 2012 estimates of wildfire likelihood and intensity generated for the Fire Program Analysis system (FPA) using the Large Fire Simulator (FSim). Areas with higher WFP values, therefore, represent fuels with a higher probability of experiencing high-intensity fire with torching, crowning, and other forms of extreme fire behavior under conducive weather conditions. On its own, WFP does not provide an explicit map of wildfire threat or risk, because no information on the effects of wildfire on specific values such as habitats, structures, or infrastructure is incorporated in its development. It is important to note that the WFP is also not a forecast or wildfire outlook for any particular season, as it does not include any information on current or forecasted weather or fuel moisture conditions.

About the Data :

CAL FIRE Locations and Perimeters: Since CAL FIRE does not always send daily updates to the USGS GeoMAC we are utilizing their KML feed to keep this map up to date. Please note - these can conflict with information from the USGS Wildfire Activity feed below.

Wildfire Activity: This displays large active fire incidents and situation reports that have been entered into the National Interagency Fire Center (NIFC) database by local emergency response teams. The Active Fire Perimeters layer is a product of Geospatial Multi-Agency Coordination (GeoMAC). Wildland fire perimeter data provided by the GeoMAC site are derived from data produced by GIS specialists working on each incident. Perimeter data displayed in and delivered by the GeoMAC application are not the final or official perimeters for any incident and are provided for informational purposes only. The final official perimeter should be obtained from the host unit, which can be determined by looking at the Unit Id for any specific fire. The host unit is responsible for producing official and final perimeters for all incidents in their jurisdiction. Data source: USGS Rocky Mountain Geographic Science Center Outgoing Data Sets, also see GeoMAC metadata for more information.

Hot Spot: The MODIS thermal layer is created from the MODIS satellite detection system and represents hot spots that could be potential fire locations in the last 24 hour period at a horizontal resolution of 1 km and temporal resolution of 1 to 2 days. For information see our explanation in the description here. Data source: NASA EOSDIS website

Wind Data (NOAA METAR): Typical METAR contains data for the temperature, dew point, wind speed and direction, precipitation, cloud cover and heights, visibility, and barometric pressure. A METAR may also contain information on precipitation amounts, lightning, and other information.

Wildfire Potential: This is a raster geospatial product produced by the USDA Forest Service, Fire Modeling Institute, intended to be used in analyses of wildfire risk or hazardous fuels prioritization at large landscapes (100s of square miles) up through regional or national scales.

Description
Cal FIRE is the only authoritative fire data source for the State of California.
All other sources are non-authoritative.

Feature layer showing the active fires being tracked by Cal OES GIS.

Fire information is taken from the National Fire and Aviation Management (FAMWEB) in the form of ICS-209 reports. During normal operations these 209 reports are downloaded once a day at 0630, or soon after. During a SOC activation these 209 reports will be downloaded twice a day at 0630 and 1800. Cal OES GIS considers the FAMWEB ICS-209s as the authoritative fire information source.

Fire perimeter data is downloaded from the National Interagency Fire Center (NIFC).

The data for map is updated daily, M-F, by 0800, the map text by 0900, when there are active fires being tracked by Cal OES.

If the SOC is activated the fire map will be updated daily, Sun-Sat, by 0800, the map text by 0900, until the SOC stands down.

For a fire to be tracked by Cal OES GIS it needs to be:
>100 acres in size
Have an ICS-209 form.

Description

WFIGS_Logo_withText

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 out
Has not had fire report records completed (certified)
Is Valid and not "quarantined" in IRWIN due to potential conflicts with other records
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 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 days
Fire size is between 10 and 100 acres (Size Class C) and fire information hasn't been updated in more than 8 days
Fire 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. More detail about the NWCG Wildland Fire Event Polygon standard can be found here.

Description

This data set is part of an ongoing project to consolidate interagency fire perimeter data. The record is complete from the present back to 2020.

The incorporation of all available historic data is in progress.

The InFORM (Interagency Fire Occurrence Reporting Modules) FODR (Fire Occurrence Data Records) are the official record of fire events. Built on top of IRWIN (Integrated Reporting of Wildland Fire Information), the FODR starts with an IRWIN record and then captures the final incident information upon certification of the record by the appropriate local authority.

This service contains all wildland fire incidents from the InFORM FODR incident service that meet the following criteria:

Categorized as a Wildfire (WF) or Prescribed Fire (RX) record
Is Valid and not "quarantined" due to potential conflicts with other records

No "fall-off" rules are applied to this service.

Service is a real time display of data.

Description
Feature layer showing all the fires tracked by Cal OES GIS for the year to date.

Fire information is taken from the National Fire and Aviation Management (FAMWEB) in the form of ICS-209 reports. During normal operations these 209 reports are downloaded once a day at 0630, or soon after. During a SOC activation these 209 reports will be downloaded twice a day at 0630 and 1800. Cal OES GIS considers the FAMWEB ICS-209s as the authoritative fire information source.

Fire perimeter data is downloaded from the National Interagency Fire Center (NIFC).

The data for map is updated daily, M-F, by 0800, the map text by 0900, when there are active fires being tracked by Cal OES.

If the SOC is activated the fire map will be updated daily, Sun-Sat, by 0800, the map text by 0900, until the SOC stands down.

For a fire to be tracked by Cal OES GIS it needs to be:
>100 acres in size
Have an ICS-209 form.

CalOES GIS indicates a fire as contained when it has reached >=90% containment.

Description
Initial attack frequency zones are used by pilots and dispatchers for purposes of response to incidents such as wildland fires. Initial attack frequency zones are agreed upon annually by the Communications Duty Officer at the National Interagency Fire Center (NIFC), other frequency managers, and the FAA, and can't be changed during the year without required approval from the CDO at NIFC. Each zone has assigned to it FAA-issued frequencies that are to be used only within the zone boundary. The initial attack frequency zones are delineated to help ensure that frequencies used do not "bleed" over into other incident areas and causing issues for incident communications. The data contains no actual frequencies, but does contain the zones in which they are used.
01/12/2023 - Tabular changes only. Oregon Initial Attack Frequency Zones renumbered per Kim Albracht, Communications Duty Officer, with input from other Northwest personnel. Edits by JKuenzi, USFS. Changes are as follows:
OR09 changed to OR02
OR02 changed to OR03
OR03 changed to OR04
OR04 changed to OR05
OR05 changed to OR07
OR07 changed to OR08
OR08 changed to OR09
OR01 and OR06 remained unchanged.
01/10/2023 - Geospatial and tabular changes made. Two islands on west side of OR05 absorbed into OR03. Change made to both Initial Attack Frequency Zones-Federal and to Dispatch Boundaries per Kaleigh Johnson (Asst Ctr Mgr), Jada Altman (Dispatch Ctr Mgr), and Jerry Messinger (Air Tactical Group Supervisor). Edits by JKuenzi, USFS.
01/09/2023 - Geospatial and tabular changes to align Federal Frequency Zones to Dispatch Area boundaries in Northwest GACC. No alignments made to USWACAC, USWAYAC, or USORWSC. Changes approved by Ted Pierce (NW Deputy Coordination Ctr Mgr), Kaleigh Johnson (Assistant Ctr Mgr), and Kim Albracht (Communications Duty Officer). Edits by JKuenzi, USFS. Specific changes include:
WA02 changed to WA04.
New WA02 carved out of WA01 and OR01.
OR09 carved out of OR01 and OR02.
Boundary adjustments between OR07, OR05, and OR03.
11/8/2022 - Geospatial and tabular changes. Boundary modified between Big Horn and Rosebud Counties of MT07 and MT08 per KSorenson and KPluhar. Edits by JKuenzi, USFS.

Boundary modified between CA03 and NV03, specifically between Queen Valley and Mono Valley. The team making the changes is made up of Southern Calif (JTomaselli) and Great Basin (GDingman) GACCs, with input from Ian Mills and Lance Rosen (BLM). Changes proposed will be put into effect for the 2023 calendar year, and will also impact alignments of GACC boundaries and Dispatch boundaries in the area described. Initial edits provided by Ian Mills and Daniel Yarborough. Final edits by JKuenzi, USFS.
A description of the change is as follows:
The northwest end of changes start approximately 1 mile west of Mt Olsen and approximately 0.5 mile south of the Virginia Lakes area.
Head northwest passing on the northeast side of Red Lake and the south side of Big Virginia Lake to follow HWY 395 North east to CA 270.
East through Bodie to the CA/NV state line.
Follows the CA/NV State Line south to HWY CA 167/NV 359.
East on NV359 to where the HWY intersects the corner of FS/BLM land.
Follows the FS/BLM boundary to the east and then south where it ties into the current GACC boundary.
09/07/2022 - 09/08/2022 - Tabular and geospatial changes. Multiple boundaries modified in Northern Rockies GACC to bring Dispatch Boundaries and Initial Attack Frequency Zone lines closer in accordance with State boundaries. Information provided by Don Copple, State Fire Planning & Intelligence Program Manager for Montana Dept of Natural Resources & Conservation (DNRC), Kathy Pipkin, Northern Rockies GACC Center Manager, and Kat Sorenson, R1 Asst Aircraft Coordinator. Edits by JKuenzi, USFS. The following changes were made:

Description
Initial attack frequency zones are used by pilots and dispatchers for purposes of response to incidents such as wildland fires. Use of international initial attack frequency zones would be coordinated as needed by the Communications Duty Officer at the National Interagency Fire Center (NIFC), Initial attack frequency zones are delineated to help ensure that frequencies used do not "bleed" over into other nearby incident areas causing issues for incident communications. The data contains no actual frequencies, but does contain the zone identifier.
2/3/2022 - Northern and western boundaries of WA01-N modified by Kim Albracht, Communications Duty Officer (CDO), to follow international border between Vancouver Island and Washington State. All changes specifically made for use in CFETS (Communication Frequency, Equipment, Tracking System) program during 2022. Edits by JKuenzi.
6/1/2021 - Northern boundary of WA01-N modified by Kim Albracht, Communications Duty Officer (CDO), to include part of Vancouver Island and a new western border. Boundary between WA01-N and WA01-S modified to match specific latitude/longitude points. Boundary between WA03-N and WA03-S modified to match specific latitude/longitude points. Label for 2 small parcels of land in Montana changed from MT04-N to MT04-S. All changes specifically made for use in CFETS (Communication Frequency, Equipment, Tracking System) program during 2021. Edits by JKuenzi.
12/2/2020 - Data derived from existing Federal Initial Attack Frequency Zone data and modified as directed by Kim Albracht, Communications Duty Officer (CDO) at the National Interagency Fire Center (NIFC). Polygons represent a starting point from which coordination would begin in the event of a wildfire or other incident with the potential to impact lands in the United States and Canada.

Description
Predictive Service Areas (PSAs) are geographic areas for which national-level fire weather or fire danger services and products are produced by wildland fire agency meteorologists and intelligence staffs in support of resource allocation and prioritization. A PSA boundary defines areas where 2 or more weather elements or National Fire Danger Rating System (NFDRS) indices exist with a high correlation to historical significant fire size. "Significant fires" are the 95th percentile fire size for the PSA.
1/9/2023 - Spatial and tabular changes made at request of Basil Newmerzhycky (Great Basin), and Gina McGuire (Fire Meterologist). PSA boundaries between Great Basin (GB14) and Northern California (NC08) GACCs aligned to follow GACC boundary in area of East Fork High Rock Canyon Wilderness and Grassy Canyon. Edits by JKuenzi.
8/29/2022 - 8/30/2022 - Spatial and tabular changes made at request of Southern Area GACC (submitted by Dana "Nancy" Ellsworth and Subject Matter Experts). Edits by JKuenzi. Specific changes include:
Puerto Rico changed from 6 PSAs to 1 PSA. PSAName changed to PR for all areas. PSANationalCode changed to "SA52A" for all areas. PSANames and PSANationalCodes = "PR Northwest (number SA52A remains active), PR Southwest (SA52B), PR North (SA53), PR Central (SA54), PR South (SA55), and PR East (SA56)" were all removed.
Florida changed from 10 PSAs to 4 PSAs. PSANames and PSANationalCodes = "FL North Coast (SA44), FL Northeast (SA45A), FL Northeast Coast (SA45B), FL Pan (SA43), FL SE Coast (SA51B), and FL SW Coast (SA51A)" were all removed. Remaining PSAs realigned using linework by AHepworth, and authoritative datasets (Census Counties, and PADUS Modified Jurisdictional Boundaries) to cover all of Florida.
Louisiana changed PSAName from "MS South" to "LA East" where PSANationalCode = "SA22B" .
1/12/2022 - Spatial and tabular changes made while assigning PSAs to islands and merging a handful of small slivers with larger areas Islands identified by Geographic Area Coordination Center (GACC) PSA representatives, Heidi Strader, Julia Rutherford, Dana "Nancy" Ellsworth, and Matt Shameson. Edits by JKuenzi.
1/10/2022 - Spatial and tabular changes made as part of the request to replace all PSAs in the Rocky Mountain Geographic Area Coordination Center (GACC) by Valerie Meyers and Coleen Haskell, both Predictive Services Fire Weather Meteorologists. The total number of PSAs within the Rocky Mountain area went from 74 to 28. Along with new linework, PSAs were re-numbered and named. Topology was used to find and remove gaps and overlaps.Edits by JKuenzi.
10/29/2021 - Spatial changes made. Coastlines matched to other base data layers including: Geographic Area Coordination Centers (GACCs), Dispatch Areas, and Initial Attach Frequency Zones. Process completed with approval from the PSA representatives in each GACC, in order to begin process of vertical integration of PSA data, where appropriate, with other wildland fire base data layers. No interior lines moved except along coast. A few island areas were not specifically labeled with a PSA and have been assigned a PSANationalCode = "None" and "PSAName = "No PSA Assigned". Edits by JKuenzi,
10/25/2021 - Spatial and tabular changes made resulting from proposed change between Southwest and Southern Geographic Area Coordination Centers (GACCs) for use starting 1/10/2022. Seven Predictive Service Areas re-aligned boundaries as described by Charles Maxwell (USFS) Predictive Services Meteorologist, in conjunction with Rich Naden (NPS), Basil Newmerzhycky (BLM), Dana Ellsworth (USFS), and Calvin Miller (USFS). Edits by JKuenzi, USFS. Specific changes made include:
SW13 - split at Texas/New Mexico state line. Area in NM remains SW13. Area in TX/OK becomes SA01.
SW14N - split at Texas/New Mexico state line. Area in NM remains SW14N. Area in TX is split into SA04 and SA09
SW14S - split at Texas/New Mexico state line. Area in NM absorbed by SW14N. Area in TX is split into SA09 and SA08 along county lines.
SW09 - split at Texas/New Mexico state line. Area in NM remains SW09 or is absorbed by SW12. Area in TX is absorbed by SA08.
SW12 - absorbs sliver of SW09 along TX/NM border and the Guadalupe Mtns in TX.
10/20/2021-10/21/2021 - Spatial and tabular changes made while completing topology checks for overlaps and gaps. Over 3400 errors found, but most were because of islands. 1367 errors remain, but are all marked as exceptions. Only major changes, such as complete deletion and re-creation of polygons were noted in the Comments or DateCurrent field. Edits by JKuenzi, USFS.
2/3/2021 - Tabular change made in Alaska to the peninsula where the St. Michael Airport is located. PSA National Code changed from AK14 to AK08 per Nicholas Nauslar, BLM, and Heidi Strader, Fire Weather Program Mgr at Alaska Interagency Coordination Center. Edits by JKuenzi, USFS.
6/20/2020 - PSA dataset attribute table brought into alignment with NWCG Data Standards for Predictive Service Areas. Edits by JKuenzi, USFS.
8/3/2019 - Great Basin updated. Edits by DSampson, BLM.

Description
Feature layer showing all the fires tracked by Cal OES GIS for the year to date.

Fire information is taken from the National Fire and Aviation Management (FAMWEB) in the form of ICS-209 reports. During normal operations these 209 reports are downloaded once a day at 0630, or soon after. During a SOC activation these 209 reports will be downloaded twice a day at 0630 and 1800. Cal OES GIS considers the FAMWEB ICS-209s as the authoritative fire information source.

Fire perimeter data is downloaded from the National Interagency Fire Center (NIFC).

The data for map is updated daily, M-F, by 0800, the map text by 0900, when there are active fires being tracked by Cal OES.

If the SOC is activated the fire map will be updated daily, Sun-Sat, by 0800, the map text by 0900, until the SOC stands down.

For a fire to be tracked by Cal OES GIS it needs to be:
>100 acres in size
Have an ICS-209 form.

CalOES GIS indicates a fire as contained when it has reached >=90% containment.

Description
The National Incident Feature Service (NIFS) is based on the National Wildfire Coordinating Group (NWCG) data standard for Wildland Fire Event. The Wildland Fire Event data standard defines the minimum attributes necessary for collection, storage and dissemination of incident based data on wildland fires (wildfires and prescribed fires). The standard is not intended for long term data storage, rather a standard to assist in the creation of incident based data management tools, minimum standards for data exchange, and to assist users in meeting GIS Standard Operating Procedures on Incidents (GSTOP). The intent of this standard is to update existing data formats and provide a common set of attributes for use on wildland fires starting fire season 2016.

Historical Fires
Last updated on 06/17/2022

Overview
The national fire history perimeter data layer of conglomerated Agency Authoratative perimeters was developed in support of the WFDSS application and wildfire decision support for the 2021 fire season. The layer encompasses the final fire perimeter datasets of the USDA Forest Service, US Department of Interior Bureau of Land Management, Bureau of Indian Affairs, Fish and Wildlife Service, and National Park Service, the Alaska Interagency Fire Center, CalFire, and WFIGS History. Perimeters are included thru the 2021 fire season. Requirements for fire perimeter inclusion, such as minimum acreage requirements, are set by the contributing agencies.
WFIGS, NPS and CALFIRE data now include Prescribed Burns.
Data Input
Several data sources were used in the development of this layer:
Alaska fire history
USDA FS Regional Fire History Data
BLM Fire Planning and Fuels
National Park Service - Includes Prescribed Burns
Fish and Wildlife Service
Bureau of Indian Affairs
CalFire FRAS - Includes Prescribed Burns
WFIGS - BLM & BIA and other S&L
Data Limitations
Fire perimeter data are often collected at the local level, and fire management agencies have differing guidelines for submitting fire perimeter data. Often data are collected by agencies only once annually. If you do not see your fire perimeters in this layer, they were not present in the sources used to create the layer at the time the data were submitted. A companion service for perimeters entered into the WFDSS application is also available, if a perimeter is found in the WFDSS service that is missing in this Agency Authoratative service or a perimeter is missing in both services, please contact the appropriate agency Fire GIS Contact listed in the table below.
Attributes
This dataset implements the NWCG Wildland Fire Perimeters (polygon) data standard.
https://www.nwcg.gov/sites/default/files/stds/WildlandFirePerimeters_definition.pdf

IRWINID - Primary key for linking to the IRWIN Incident dataset. The origin of this GUID is the wildland fire locations point data layer. (This unique identifier may NOT replace the GeometryID core attribute)

INCIDENT - The name assigned to an incident; assigned by responsible land management unit. (IRWIN required). Officially recorded name.

FIRE_YEAR (Alias) - Calendar year in which the fire started. Example: 2013. Value is of type integer (FIRE_YEAR_INT).

AGENCY - Agency assigned for this fire - should be based on jurisdiction at origin.

SOURCE - System/agency source of record from which the perimeter came.

DATE_CUR - The last edit, update, or other valid date of this GIS Record. Example: mm/dd/yyyy.

MAP_METHOD - Controlled vocabulary to define how the geospatial feature was derived. Map method may help define data quality.
GPS-Driven; GPS-Flight; GPS-Walked; GPS-Walked/Driven; GPS-Unknown Travel Method; Hand Sketch; Digitized-Image; Digitized-Topo; Digitized-Other; Image Interpretation; Infrared Image; Modeled; Mixed Methods; Remote Sensing Derived; Survey/GCDB/Cadastral; Vector; Other

GIS_ACRES - GIS calculated acres within the fire perimeter. Not adjusted for unburned areas within the fire perimeter. Total should include 1 decimal place. (ArcGIS: Precision=10; Scale=1). Example: 23.9

UNQE_FIRE_ - Unique fire identifier is the Year-Unit Identifier-Local Incident Identifier (yyyy-SSXXX-xxxxxx). SS = State Code or International Code, XXX or XXXX = A code assigned to an organizational unit, xxxxx = Alphanumeric with hyphens or periods. The unit identifier portion corresponds to the POINT OF ORIGIN RESPONSIBLE AGENCY UNIT IDENTIFIER (POOResonsibleUnit) from the responsible unit’s corresponding fire report. Example: 2013-CORMP-000001

LOCAL_NUM - Local incident identifier (dispatch number). A number or code that uniquely identifies an incident for a particular local fire management organization within a particular calendar year. Field is string to allow for leading zeros when the local incident identifier is less than 6 characters. (IRWIN required). Example: 123456.

UNIT_ID - NWCG Unit Identifier of landowner/jurisdictional agency unit at the point of origin of a fire. (NFIRS ID should be used only when no NWCG Unit Identifier exists). Example: CORMP

COMMENTS - Additional information describing the feature. Free Text.

FEATURE_CA - Type of wildland fire polygon: Wildfire (represents final fire perimeter or last daily fire perimeter available) or Prescribed Fire or Unknown

GEO_ID - Primary key for linking geospatial objects with other database systems. Required for every feature. This field may be renamed for each standard to fit the feature. Globally Unique Identifier (GUID).

Cross-Walk from sources (GeoID) and other processing notes

Description

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) record
Fire Discovery Date is in the year 2023
Is Valid and not "quarantined" in IRWIN due to potential conflicts with other records
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 2023 Wildland Fire Incident Locations to Date service.

No "fall-off" rules are applied to this 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.

Description
This layer presents the best-known point and perimeter locations of wildfire occurrences within the United States over the past 7 days. Points mark a location within the wildfire area and provide current information about that wildfire. Perimeters are the line surrounding land that has been impacted by a wildfire.

Source:  Wildfire points are sourced from Integrated Reporting of Wildland-Fire Information (IRWIN) and perimeters from National Interagency Fire Center (NIFC). 

Current Incidents: This layer provides a near real-time view of the data being shared through the Integrated Reporting of Wildland-Fire Information (IRWIN) service. IRWIN provides data exchange capabilities between participating wildfire systems, including federal, state and local agencies. Data is synchronized across participating organizations to make sure the most current information is available. The display of the points are based on the NWCG Fire Size Classification applied to the daily acres attribute.

Current Perimeters: This layer displays fire perimeters posted to the National Incident Feature Service. It is updated from operational data and may not reflect current conditions on the ground. For a better understanding of the workflows involved in mapping and sharing fire perimeter data, see the National Wildfire Coordinating Group Standards for Geospatial Operations.

Update Frequency:  Every 15 minutes using the Aggregated Live Feed Methodology based on the following filters:
Events modified in the last 7 days
Events that are not given a Fire Out Date
Incident Type Kind: Fires
Incident Type Category: Debris/Product Fire, Fire Rehabilitation, Incident/Event Support, Preparedness/Preposition, Prescribed Fire, Wildfire, Wildland Fire Use, Incident Complex, and Out of Area Response
Area Covered: United States

What can I do with this layer? 
The data includes basic wildfire information, such as location, size, environmental conditions, and resource summaries. Features can be filtered by incident name, size, or date keeping in mind that not all perimeters are fully attributed.

The USA Wildfires web map provides additional layers and information such as Red Flag warnings, wind speed/gust, and satellite thermal detections. This map can be used as a starting point for your own map.

Attribute Information
This is a list of attributes that benefit from additional explanation. Not all attributes are listed.

Incident Type Category: This is a breakdown of events into more specific categories.

IrwinID: Unique identifier assigned to each incident record in both point and perimeter layers.

Acres: these typically refer to the number of acres within the current perimeter of a specific, individual incident, including unburned and unburnable islands.
Discovery: An estimate of acres burning upon the discovery of the fire.
Calculated or GIS:  A measure of acres calculated (i.e., infrared) from a geospatial perimeter of a fire.
Daily: A measure of acres reported for a fire.
Final: The measure of acres within the final perimeter of a fire. More specifically, the number of acres within the final fire perimeter of a specific, individual incident, including unburned and unburnable islands.
Dates: the various systems contribute date information differently so not all fields will be populated for every fire.
FireDiscovery: The date and time a fire was reported as discovered or confirmed to exist. May also be the start date for reporting purposes.
Containment: The date and time a wildfire was declared contained.
Control: The date and time a wildfire was declared under control.
ICS209Report: The date and time of the latest approved ICS-209 report.
Current: The date and time a perimeter is last known to be updated.
FireOut: The date and time when a fire is declared out.
GACC: A code that identifies one of the wildland fire geographic area coordination centers. A geographic area coordination center is a facility that is used for the coordination of agency or jurisdictional resources in support of one or more incidents within a geographic coordination

Description

This ArcGIS Online hosted feature service displays perimeters from the National Incident Feature Service (NIFS) that meet ALL of the following criteria:

FeatureCategory = 'Wildfire Daily Fire Perimeter'
IsVisible = 'Yes'
FeatureAccess = 'Public'
FeatureStatus = 'Approved'.

This dataset is made up of current, active wildfires. On a weekly basis, fires meeting specific criteria are removed from the source service. After removal, those perimeters can be found in the associated "Archived Wildfire Perimeters" service. Criteria include:

Perimeters are identified with an IRWIN ID that has non-null values in IRWIN for ContainmentDateTime, ControlDateTime, or FireOutDateTime
The most recent controlled/contained/fire out date is greater than 14 days old
No IRWIN ID
Last edit (based on DateCurrent) is greater than 30 days old

This hosted feature service is not "live", but is updated every 5 minutes to reflect changes to perimeters posted to the National Incident Feature Service. It is updated from operational data and may not reflect current conditions on the ground. For a better understanding of the workflows involved in mapping and sharing fire perimeter data, see the NWCG Geographic Information System Standard Operating Procedures On Incidents (GSTOP) and most recent addendums: https://www.nwcg.gov/publications/936.

To use this service from the Open Data site in a web map, click the APIs down arrow, copy the GeoService URL (remove the /query? statement) or just copy and paste this URL and add it to a web map (Add > Add Layer from Web): https://services3.arcgis.com/T4QMspbfLg3qTGWY/arcgis/rest/services/Public_Wildfire_Perimeters_View/FeatureServer

From within ArcGIS Online, open this feature service in a new web map by clicking Open in Map Viewer.

Once this service has been added to a web map, the features can be filtered by incident name, GACC, Create Date, or Current Date, keeping in mind that not all perimeters are fully attributed. Not all data are editable through this service and delete is disabled. To delete features, open in ArcGIS Pro or ArcMap.
