The map was of the city. The hospital was a the bottom left corner, and the X was in the middle. Shoe stopped and showed Beosta the map, running his finger across a street that headed North, then East, then North again, then East again, then South. Or at least it was probably North, East,and South. The map didn't have a compass rose on it.
Either way, they would figure the orientation out when they got outside. It didn't seem like a particularly hard map to follow. Shoe stepped outside, looked between the map and their surroundings a few times, then started off away from the hospital, waving for the others to follow.
