Arnis

Turns real-world map and elevation data into Minecraft worlds

Website

What it is

A desktop and command-line generator that builds Minecraft Java, Bedrock, and Luanti worlds from OpenStreetMap features and real elevation data. You pick an area on a map, and it places buildings, roads, water, and terrain at a chosen scale, with options for interiors, winter or post-apocalyptic styles, and a single persistent world that grows with each run. Players use it to explore their hometown or a city in-game, and teachers and builders use it as a base for projects.
