About this Mod
OpenMineMap is a Minecraft mod made for the BuildTheEarth project that implements a map of the Earth that corresponds to the BuildTheEarth Minecraft world.
- Right click on the map to copy or teleport to coordinates
- See where you are at all times with the HUD map
- View real-world mapping data, courtesy of OpenStreetMap
- Copy coordinates with a single keybind
- Determine where you're facing using the compass
Note that the map is specifically designed only to work with worlds generated with BuildTheEarth's modified dymaxion projection; the map will not display correctly with any other projection.
