Chunkmap

Chunkmap is a tool you can use in the terminal to generate a top-down 2D map of your Minecraft world. It works for the Overworld, the Nether, and The End.

Chunkmap uses your world's region (.mca) files to generate the map, meaning you'll see your builds and only the chunks that have been explored.

Chunkmap is open-source; the CLI is available on GitHub. This site is a web version of Chunkmap so you can try it out.

Chunkmap is under development and may not work as expected.
