Ewers grew up skiing and hiking in the Highlands, giving him a clear idea of the complicated challenges involved in rescue operations there. "There wasn't much to do growing up, other than spending time outdoors or sitting in front of my computer," he says. "I ended up doing a lot of both." To start, Ewers took datasets of search and rescue cases from around the world, which include details such as an individual's age, whether they were hunting, horseback riding or hiking, and if they suffered from dementia, along with information about the location the person was eventually found--by water, buildings, open ground, trees, or roads. He trained an AI model with this data, in addition to geographical data from Scotland.
