Pin a map
to the world.

Place control points in the Allmaps Editor to anchor each map to real-world coordinates. No specialist software needed — just a browser.

How it works

  1. Pick a map below and hit Open in Allmaps.
  2. Drop at least 3 ground control points — match a spot on the map to the same spot on the modern world.
  3. Save in Allmaps. Nothing to send back: the archive checks Allmaps for finished maps and marks them georeferenced by itself.
