Hi All,

I’m a lurker, don’t want to discourage this, and hope you’ll find a good way to apply LoRa technology to fire support activities as you proceed.  So far, though, there has been no mention of the current state of the art for detecting wild/forest fires.  Start here for example:

https://firms.modaps.eosdis.nasa.gov/map/#d:2021-02-01..2021-02-02;@-121.2,38.0,9z <https://firms.modaps.eosdis.nasa.gov/map/#d:2021-02-01..2021-02-02;@-121.2,38.0,9z> 

This map aggregates data collected from satellites equipped with supercooled infrared sensors, such as NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) satellites. On high fire danger days in California, this data is supplemented in realtime by high flying aircraft carrying similar sensors.  My understanding is the current problem is not the ability to detect a fire as it starts, but getting the necessary resources in place quickly enough to extinguish it before it spreads beyond control.  The major loss of life and property in California typically occurs when the wind has been blowing at 50+ MPH.  Even if one fire is successfully extinguished, others will be started (sometimes miles away) by airborne embers from the first.  The morning after we had the large thunderstorms in the Bay Area, the FIRMS map was covered with hundreds of red dots, along with several large conflagration areas. By that point, state/county/USFS fire crews have to choose which fires to address and hope the rest can be handled locally or burn themselves out.

Best regards,
Marc
