Drones may be used to monitor Sweden's forests around the clock. But drones today have difficulty distinguishing between fire smoke and fog.

Julia Åhlén has developed an algorithm that will help the drones quickly identify forest fires. In recent years, Sweden has been hit by a series of extensive forest fires that have caused major material damage. But for this to become a reality, drones need to be smart enough to find suspicious fires and make accurate assessments. The algorithm today identifies 90 percent of the images correctly.
