Use drones with IR cameras:
* Find deer after they're shot. Right now you need to hire a blood hound and it takes hours
* Do wildlife surveys for conservation and management departments
* Pest management for farmers

They tried this exact thing with the kentucky freeway shooter using both helicopter based FLIR system and IR camera equipped drones and failed. Eventually the dudes body was found by a group of ... as far as i can tell, wilderness youtubers working with a police search party.
Even the dogs didn't find him.
I'm picturing bumper-to-bumper traffic on a highway with a cloud of drones overhead. Each person in their individual car using their individual drone to all report back the same thing: that everything is moving slowly because there are just too many cars on the road right now. With luck, the drones only crash into each other every once in a while, just like the cars below.
Thermal is really good in the UK because the ground is rarely that warm. You can easily see a person hiding among rocks, for example. It's basically Cops. In equatorial Africa you can only use it at dawn/dusk (or overnight) because the ground is so hot.
Pest management is a heck of a good idea. The province of Alberta is officially rat free - if Alberta doesn’t have something like this I bet they would be interested. Especially if it could do double duty for wildlife surveys.
