This could be good for people who want to create a treasure map on a server. The recipe would be a banner (any color) in the middle instead of a compass, surrounded by paper. It would create an empty map like a normal map/exploration map. When it's opened (presumably from far away), it will show an unexplored area with an X on it. The X would be the spot you were standing on when this map was crafted. Like normal maps, it could be zoomed out to whatever level you want.
