Online Map Overviewer
For those who have been wondering what it would look like to see their build zoomed out, or wanted to find out coordinates of an old build, the online map can help you. Note: Only builds on the surface can be seen.
If you're looking for a previous map, simply select the dropdown box in the top-right corner and select the map you're looking for (maps are labelled by the version they finished).
When you've found the map you are looking for, you can find coordinates of your build in the bottom-left corner
