Runs on your computer, in this tab. Java Edition 1.21.
The Earth Map Generator builds a playable Minecraft world from any spot on the planet. Pick an area on the map, and it recreates the real buildings, streets, rivers, terrain and vegetation as blocks, ready to explore in singleplayer.
Everything happens in your browser. The generator downloads the map data for your selected area, then builds the world on your own computer: no upload, no server queue, no account. When it finishes you get a zip with a normal Java Edition world folder inside.
Building shapes and streets come from OpenStreetMap, the same map data used by navigation apps. Terrain height comes from satellite elevation data, so hills, valleys and coastlines are real. Ground cover like forests, sand and water is read from satellite imagery.
1. Search for a city, address or landmark, or just pan the map to the spot you want.
2. Pick a preset size or use the draw tool to drag a box over the exact area.
3. Choose the generation mode, game mode and time of day. Optionally click a spawn point inside your area.
4. Hit Generate and keep the tab open. Small areas finish in about a minute.
5. Unzip the download into your .minecraft/saves folder. The world appears in the singleplayer list.
Buildings are placed on their real footprints with mapped heights where available, so a church looks different from an office block. Roads, paths, bridges and rail lines follow their actual routes. Rivers, lakes and coastlines are carved with depth, and the terrain under everything uses real elevation, so a hillside town sits on an actual hill.
You also spawn with a locked map item of the whole area in your inventory, which makes it easy to orient yourself. Choose Buildings + real terrain for the full result, flat ground if you want a classic superflat feel, or terrain only for an empty landscape to build on.
Yes. Search for your address, draw a small box around it, and generate. The world is built from real map data, so your street layout, nearby buildings, parks and rivers all come out in blocks.
Yes. It runs entirely in your browser, there is no account, no queue and no payment. Larger areas simply take longer to generate on your own computer.
Not yet. The generator currently produces Java Edition worlds for Minecraft 1.21 and newer. You can convert the result with a world converter if you need it on Bedrock.
Up to 4 square kilometers per world, which covers a full city center. Generation happens on your computer, so bigger areas take longer: a few blocks is about a minute, the maximum size can take over ten minutes.
Buildings, streets and water come from OpenStreetMap. Terrain height comes from satellite elevation data, and ground surfaces like forest, sand and water bodies come from ESA WorldCover satellite imagery.
The world can only be as complete as the map data for that spot. Well-mapped cities come out with almost every building; rural areas may have gaps. You can add missing buildings on openstreetmap.org and regenerate later.
