Currently, only "areas" support terrain (elevation) data. It would be great to have a mission where the drone flies from manually set waypoint to manually set waypoint while being terrain aware (along a line). It would also be great to have the drone automatically take pictures in between waypoints, not just at the waypoints, only using forward overlap.
