Use Firesource to view active wildfire incidents and perimeters, create awareness for local fires, check air quality, and view satellite detections for fire growth.

Firesource’s features:
◦ Live fire feed - simply press refresh to instantly update your feed of fires on the map and in the scrollable menu
◦ View national fire incidents - to be informed of wildfires and their progress, browse through the detailed incident updates and reports
◦ View fire perimeters - access realtime fire perimeters with information about fire growth and progress, including acreage, containment, personnel, fire cause, and fire behavior
◦ Report a fire - instantly inform other users of a nearby fire by pressing the + button, taking a picture of the fire, and submitting
◦ Air quality - see the effects of recent fires by viewing realtime air quality measurements across the country
◦ Satellite fire detections can indicate new fires and how current fires are spreading

National Fires (InciWeb and Cal Fire):
InciWeb is an interagency incident management system run by the National Wildfire Coordinating Group. InciWeb collects wildfire incident data from several agencies across the United States and provides all of this data together in several feeds. Firesource presents wildfire incidents reported by InciWeb in real time, providing the fire’s location and detailed status. Learn more about InciWeb at their website: Learn more about Cal Fire, which also provides incident information, at their website:

National Fires (Perimeters):
Perimeter data is provided by the Wildland Fire Interagency Geospatial Services (WFIGS) Group and hosted in the National Interagency Fire Center ArcGIS Online Organization (The NIFC Org). Firesource displays fire perimeters and descriptions of their progress in the ‘National Fires’ tab of the menu, with this information updated on a regular basis. Learn more about the NIFC at their website:

User-Reported Fires:
Allowing app users to report a fire and immediately inform other users is an essential aspect of Firesource. To report a fire, press the yellow + button in the top right corner of the map, select the type of fire (vehicle fire, forest fire, terrain fire, structure fire), take a photo of the fire, and press submit. To ensure the validity of fire reports, the user must take a photo of the fire and cannot access Camera Roll to select a picture. Please note that submitting a fire report automatically creates the report at the user’s location, to further ensure that the fire is local and valid. When viewing user-reported fires in the feed, other users can ‘rate’ the fire report by confirming that it is active, contained, or a spam reporting.

Air Quality:
Air quality measurements from across the United States are collected from, which provides national air quality data using the Air Quality Index (AQI). This data is color-coded to provide information about health concerns due to PM2.5 pollutants.

Satellite-Detected Fires:
Thermal hotspot detections are displayed and collected from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS), which is an instrument on the Terra and Aqua satellites. Information provided from MODIS about each detection includes brightness (brightness temperature in Kelvin of a fire pixel) and confidence (quality of fire pixel). These fire detections are extremely useful, as they can indicate new fires and fire spread. Learn more about MODIS at their website:

Great tool for finding wildfires.

Not only is this application a good tool, but it’s also free. Most of those other applications charge by the month and they’re not as good.

Too hard to view fire perimeters

Things I want to know right off the bat: where are the fires, how big is the active/burned area, what direction is it moving, and what’s the air quality. While this app does have perimeter info, it’s too hard to find for each fire and should be displayed on the map by default. But I do really appreciate that the app also has air quality.

I always feel like I’m fighting with the bottom menu to stay minimized, it keeps popping up and takes 1/3 of the screen. Even the minimized version of the menu uses a lot of real estate. I doubt I would ever use the feed.

This app is promising because most of the information is there, it just needs to be displayed better!


Getting better,but....

App is getting better but I think it’s weakest feature is clearly outlining the most important info about each fire in a more useful/fast way to digest.

Example: When tap on a active fire nearby, you’re taken to the fire info page and then the data that is collected for that fire is just very crudely added in a hard to read type...

I would pick this data apart and make basic info more readily available such as “containment”, “air quality”, etc.

I mean, that is the main thing we are looking for when we tap on a fire to see. So having to weed through text to find the 1 important piece of info we need is kinda mundane.

My 2 cents.

Developer Response ,

Thank you for your feedback. Certain fire info pages within the app provide data in a crude, compact manner because these pages contain detailed fire updates from InciWeb. However, the fire reports from Cal Fire and (recently added) perimeters provide information in a more readily available and concise format, clearly presenting information about acreage, containment, personnel, fire growth, fire fuel type, etc.
