I figure since there isnt a world map. Players can make their own.
With the cartography Skill:
Players will create a world map for themselves
They'd have to stop, take a moment to survey the area, then that spot is added to the map.
They could draw routes on their map when they open it up. Also, they could set what they want to be the center. So some might have the RoB as theirs, others might have there home town.
EDIT:
This could also give use to that empty slot on the radial menu.
