The MR Maps software was tested in the wild, behind the Glencoe Ski Center, where Kelly's body was eventually found. The area had been extensively searched by Glencoe Mountain Rescue, but Kelly's body had fallen into a gully, obscuring the line of sight of rescuers on the ground.
The muted colors of Kelly's clothing, meanwhile, had made him aLL but invisible from the air. However, the MR Maps software was able to pick up on the subtle differences in color and highlight Kelly's location.
