One question I have about your idea is how small is small ?

If your detection threshold is too low you'll be dispatching drones to people's campfires or grills. If it's much larger than that the fire will be too big for any drones that currently exist and/or are approved for use in the airspace to extinguish.

There's also the issue of how quickly a fire can spread. Unless you have a very dense network of firefighting assets ready to deploy at a moment's notice the fire may be too big for them to put out by the time they arrive at the scene.

They should have banned campfires and open grill cooking in known fire-prone areas, during fire-risk seasons. System design WILL require determination of 1] Smallest satellite-detectable fire sizes; 2] Size of fire-stopper bombs needed for various fire sizes; 3] system processing times for fire location, size, direction detection; 4] system response time to launch firefighting drone/s; 5] drone travel time. ... These delays can be estimated right now, and then established empirically in a short time. ... Fire-prone areas are probably known already. These system response time estimates, verified by trials, will determine how many drones / drone-stations will be needed
