Every number in this atlas cites the study it came from. The full method, including what this site withholds on purpose, is on sources and method.
This site teaches one level above the Codex's working manual: the architecture is public, the coordinates are not. This page withholds entry points, landmark constructions, volumes and read-to-point routing, exactly as the atlas does. What is shown and what is withheld.
