Voxel Map Mod for Minecraft

VoxelMap is a minimap and worldmap mod that makes a great effort to be accurate to the colors you see in the world (and your resource pack). Display your surroundings, or view the entire (explored) world. Use your mouse to click and drag the world map, and mousewheel to zoom.

The mod has useful functionality like per-dimension waypoints, mob icons, teleport to waypoint (if the player has permission), and nether mapping. Optional chunk grid and biome overlay (with biome labels in full screen mode)
