◦ 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:

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:

Super informative

Love the breadth of information and the ability to see pics of some of the fires. Great app to have in California!

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.
