The JourneyMap mod is a great live mapper that’s super simple to use.
It is a client+server mod for Forge which maps your Minecraft world in real-time as you explore. And it can make your Minecraft experience considerably more enjoyable by implementing a very useful feature into the game.
It has a nice, clean interface and is very detailed both in the minimap and full map. Just hit ‘J’ to bring up the full map and options menu.
You can view the map in a web browser or in-game as a Minimap or full-screen.
