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.

As I don't see a use for this outside of map-making, probably better as a mod or command.
(It would, however, introduce an interesting ability into that genre.)
