I don't think Carbonite has that feature. (But I don't use it, so I may be mistaken.) It takes a LOT of work to find all of those textures in the game files, piece them together, etc, etc. This requires a full world map replacement - it's not just something you can get to show up.
Atlas World Map can, though:

There may be another that's current, but I can't find it at the moment.
