Unfortunately, you've completely missed the point of the four drawings - seeing whether the drawer could identify and use likely routes that they weren't shown. If map #1 is accurate, then I can turn right when I get to the tree and take a shortcut to the brick wall, or cut across from the lamps to the green box without going through the four-road crossroad. Map #4 will be misleading at best for understanding the whole area - if I try a shortcut from that map, I'll either get to the wrong destination or leave the original area and be totally lost.
