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

National Interagency Fire Center (NIFC) official wildland maps and fire data, an open data site for searching NIFC data and applications.

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 (NIFC) ArcGIS Online Organization.The Fire Integrated Real-time Intelligence System (FIRIS) is a public-private partnership program that provides real-time intelligence data and analysis on emerging disaster incidents in California. Funded by the California Office of Emergency Services (CalOES), the funding supports aircraft, a common operating picture, and near-real-time fire modeling by WIFIRE that is available at the onset of emerging incidents.FIRIS uses the Overwatch Imaging platform, which includes an aerial infra-red (IR) platform that integrates cutting-edge technologies provided by Aevex Aviation. FIRIS has two equipped fixed-winged aircraft staffed 7 days a week at two different locations, Sacramento and Los Alamitos California. Additionally, Orange County Fire Authority order and dispatch both aircraft while CalOES administers the data. By transmitting information from satellites onboard the fixed-winged aircraft, highly accurate fire perimeter information make it to ground resources in real-time. That data is fed to Intterra’s wildfire decision support software where WIFIRE retrieves the data for predictive analytics.This public layer was created to be used by the CAL FIRE Communications Program for the CAL FIRE incident map.California Department of Forestry and Fire Protection | CAL FIRE

This data set contains a variety of data and products from the National Interagency Fire Center (NIFC) ftp site for fires that were flown by the WE-CAN and/or BB-FLUX field projects. The data and products can vary by day and fire, but typically include GIS (Geographic Information Systems) data and products as well as fire map products from the Forest Service National Infrared Operations. There are also occasional photographs and other documents sometimes included. A small number of the documents are password protected (we do not have the password). The GIS data are typically in ArcGIS shapefiles and most of the documents are in PDF format.

Direct Protection Area Polygons (DPA) as approved by the California Wildland Fire Coordinating Group (CWCG) as of March 2025. Each polygon has attribute information indicating the agency or organization with primary responsibility for wildland fire suppression in that area. Direct Protection Areas (DPA) are the areas which, by law or pursuant to the terms of this agreement, are provided wildland fire protection by the State or the Federal Agencies. DPA may include a mixture of state and federal responsibility areas (defined by the California Master Cooperative Wildland Fire Management and Stafford Act Response Agreement [CFMA]). This feature service was published by Information Management Fire and Aviation GIS for Region 5 of the USDA Forest Service. For more information on DPA, visit the California Wildland Fire Coordinating Group website.

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.Consumption Best Practices:As a service that is subject to Viral loads (very high usage), avoid adding Filters that use a Date/Time type field. These queries are not cacheable and WILL be subject to Rate Limiting by ArcGIS Online. To accommodate filtering events by Date/Time, we encourage using the included "Age" fields that maintain the number of Days or Hours since a record was created or last modified compared to the last service update. These queries fully support the ability to cache a response, allowing common query results to be supplied to many users without adding load on the service.When ingesting this service in your applications, avoid using POST requests, these requests are not cacheable and will also be subject to Rate Limiting measures.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 daysEvents that are not given a Fire Out DateIncident Type Kind: FiresIncident Type Category: Prescribed Fire, Wildfire, and Incident ComplexArea Covered: United StatesWhat 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.Attribute InformationThis 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.Wildfire (WF) -A wildland fire originating from an unplanned ignition, such as lightning, volcanos, unauthorized and accidental human caused fires, and prescribed fires that are declared wildfires.Prescribed Fire (RX) - A wildland fire originating from a planned ignition in accordance with applicable laws, policies, and regulations to meet specific objectives.Incident Complex (CX) - An incident complex is two or more individual incidents in the same general proximity that are managed together under one Incident Management Team. This allows resources to be used across the complex rather than on individual incidents uniting operational activities.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.ModifiedOnAge: (Integer) Computed days since event last modified.DiscoveryAge: (Integer) Computed days since event's fire discovery date.CurrentDateAge: (Integer) Computed days since perimeter last modified.CreateDateAge: (Integer) Computed days since perimeter entry created.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 area.Fire Mgmt Complexity: The highest management level utilized to manage a wildland fire event.Incident Management Organization: The incident management organization for the incident, which may be a Type 1, 2, or 3 Incident Management Team (IMT), a Unified Command, a Unified Command with an IMT, National Incident Management Organization (NIMO), etc. This field is null if no team is assigned.Unique Fire Identifier: Unique identifier assigned to each wildland fire. yyyy = calendar year, SSUUUU = Point Of Origin (POO) protecting unit identifier (5 or 6 characters), xxxxxx = local incident identifier (6 to 10 characters)RevisionsJan 4, 2021: Added Integer fields 'Days Since...' to Current_Incidents point layer and Current_Perimeters polygon layer. These fields are computed when the data is updated, reflecting the current number of days since each record was last updated. This will aid in making 'age' related, cache friendly queries.Mar 12, 2021: Added second set of 'Age' fields for Event and Perimeter record creation, reflecting age in Days since service data update.Apr 21, 2021: Current_Perimeters polygon layer is now being populated by NIFC's newest data source. A new field was added, 'IncidentTypeCategory' to better distinguish Incident types for Perimeters and now includes type 'CX' or Complex Fires. Five fields were not transferrable, and as a result 'Comments', 'Label', 'ComplexName', 'ComplexID', and 'IMTName' fields will be Null moving forward.Apr 26, 2021: Updated Incident Layer Symbology to better clarify events, reduce download size and overhead of symbols. Updated Perimeter Layer Symbology to better distingish between Wildfires and Prescribed Fires.May 5, 2021: Slight modification to Arcade logic for Symbology, refining Age comparison to Zero for fires in past 24-hours.Aug 16, 2021: Enabled Time Series capability on Layers (off by default) using 'Fire Discovery Date' for Incidents and 'Creation Date' for Perimeters.This layer is provided for informational purposes and is not monitored 24/7 for accuracy and currency.If you would like to be alerted to potential issues or simply see when this Service will update next, please visit our Live Feed Status Page!

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.

This is an export of the data archived from the 2024 National Incident Feature Service.Sensitive fields and features have been removed.Each edit to a feature is captured in the Archive. The GDB_FROM and GDB_TO fields show the date range that the feature existed in the National Incident Feature Service.The National Incident Feature Service 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 the NWCG Standards for Geospatial Operations (PMS 936).

This map contains live feed sources for US current wildfire locations and perimeters, VIIRS and MODIS hot spots, wildfire conditions / red flag warnings, and wildfire potential. Each of these layers provides insight into where a fire is located, its intensity and the surrounding areas susceptibility to wildfire. Find out more about the Esri Disaster Response Program: www.esri.com/disaster About the Data: Click on the links in the LAYERS section for details about each layer Wildfire: 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 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.Hot Spot: The MODIS and VIIRS thermal layers are 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. 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. Red Flag Warnings: Filtered from the Weather Watches and Warnings layer.

This dataset represents a time-enabled view of the NIFC-NWCG 7 Day Significant Fire Potential Index filtered down to California. It also includes a summary table for each regions index values for the next 7 days.This dataset is updated daily on a 15-minute interval from 5AM to 9AM PST.The primary responsibility of Predictive Services is to provide sound guidance to regional and national resource managers concerning current and projected “Significant Fire Potential”. The goal of this guidance is to help these managers make effective and efficient use of available resources. “Significant Fire Potential” is defined as “the likelihood that a wildland fire event will require mobilization of additional resources from outside the area in which the fire situation originates”.It is crucial to understand that although weather is a major contributor to Significant Fire Potential, this product is not a weather forecast. It is a forecast of Significant Fire Potential only, which is a function of fuel conditions, weather, and resource availability. It assesses the daily probability for occurrence of a new large fire and/or the daily potential for significant new growth on existing fires.Visit the NWCG National 7 Day Significant Fire Potential SiteDownload the Source DataLearn about the Product

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. No Changes January 2025.

The National Wildfire Coordinating Group's Wildland Fire Event Point 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) guidance.

This feature class will use a specific symbol set. The symbol set is defined by the GIS Standard Operating Procedures for Incidents (GSTOP). For additional information follow this link: http://gis.nwcg.gov/gstop_about.html

This feature class will be part of a Incident Geodatabase that will contain Fire Point, Fire Line, and Fire Polygon feature classes.

This standard is for incident based data collection, storage and exchange. 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.

This standard should not be confused with the NWCG geospatial data standard for Wildland Fire Location Point, which is for the representation of the final spatial location of the fire occurrence ignition.
