I know literally nothing about drones but had one over my property today. It stayed stationary just above the treeline but kept doing little one quarter turns  until fully rotated into a 360. Did this for about one minute, flew away and then came back to a slightly different position and did the same thing. The quarter turns looked very deliberate. Any idea what he was doing? I'm out in a rural area and am pretty surrounded by trees but my property itself is wide open above. Worth noting he did this for about half an hour and did a few of my  neighbors as well
