IRWIN: Current Incident Viewer and Data

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 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)
