Output format: one importable .mcworld

Using TopoBlocks to turn a real place into a Minecraft world, the final output is a .mcworld file you can import straight into Bedrock. The workflow is: search for a real place (name/address/landmark/location) → read OpenStreetMap public data (building footprints, roads, water) plus open elevation (AWS Terrain) → use the open-source arnis (Apache-2.0) to generate an importable world package.

Once you have the .mcworld, just open it on a device with Bedrock installed to import. It is not a Java Edition world, and Java Edition cannot import .mcworld directly; to learn about the format itself, see What is a .mcworld file.

One thing to be clear about: generation is an approximate recreation based on public data, not a block-by-block copy of the real buildings. City areas with high data coverage will look more accurate, while outer suburbs or data-sparse spots will look emptier—which is why “preview before you pay” matters (see below).

Four gameplay templates

The same real-map data can be paired with different starting gameplay settings. There are currently four templates:

  • Faithful Recreation—stays as close as possible to the real terrain and street layout, ideal for “bringing your hometown/a landmark into the game.”
  • Survival-Friendly—pairs it with starting resources and a spawn experience suited to survival.
  • City Explorer—focused on wandering and exploring the generated city/neighborhood.
  • Treasure Adventure—adds guided treasure-hunting gameplay.

What a template changes is the starting gameplay configuration; the underlying terrain still comes from the same OpenStreetMap + elevation data, so the accuracy is determined by data coverage, not by the template. To see specific survival gameplay, see Playing survival on a real-world map.

Check the free quality score and 3D preview before generating

Before final generation, TopoBlocks gives you two things for free so you can confirm before paying:

  1. Map quality score—a data-coverage estimate for the selected area. It reflects whether building/road/water data is complete; it is not a precision guarantee, nor does it mean a block-by-block recreation of reality.
  2. Low-resolution 3D preview—a rough look at the terrain and outlines first.

Generate for real only after you’re satisfied. Generation is priced in tiers by area (roughly 0.2–500 km², ¥19–¥239, prices shown in the app, failures refunded automatically). Whether generating or doing anything afterward, TopoBlocks never overwrites your existing saves—every time it’s a new, traceable file.
