About Arnis
Arnis generates Minecraft Java Edition (1.17+), Bedrock Edition, and Luanti (Minetest) worlds from real-world geography. It processes OpenStreetMap data and elevation data to recreate terrain, buildings, roads, and other objects.
Users select an area with the rectangle tool, choose a Minecraft world, and start generation, with settings for world scale, spawn point, building interiors, and generation modes. Use requires downloading a release or compiling the project, and the GitHub page and arnismc.com are stated as the only official sources.
