The ideal vantage point for this is right where the mission starts, but to be safe you should kill or subdue the guard who steps into the room with the altar down the stairs behind 47 so he can't hear the shots. The 'The Higher Ground' challenges are about sniping guards with headshots without getting spotted (in the meaning 47 being identified as the shooter or any of the NPCs seeing another get shot).

Firing a single shot from Agency SPS 12 into the air from a concealed position is best way to lure a guard to the starting structure in order to get the drop on him unnoticed and snag a disguise. If you want to play more humanely you will have to stay low and use a lot of distractions. You can snipe some of them at the start to clear a path.
