Visual Cartography
Visual Cartography is a resource pack dedicated to visually enhancing Minecraft's cartography system. It addresses visual gaps left by the vanilla version of the game.
Thanks to OptiFine's CIT technology, players can now immediately identify the type of adventure map they're holding. This significantly simplifies navigation on multiplayer servers and world exploration.
Since Minecraft's map system has a rigid internal structure, this pack offers an alternative solution for personalizing map appearance. You simply need to rename the map on an anvil, adding [0-26] after the name to get a unique sprite for your map.
