Purchasing another explorer map from the same cartographer results in the same explorer map. In Java Edition, each cartographer sells its own unique explorer map that points to a different location than other cartographers.
However, in Bedrock Edition, the cartographer trades for the map are unlocked, but the purchased map shows the same layout as in the corresponding dimension and shows no destination structure, but if cartographer trades are unlocked in an old world type (prior-1.11.0), the game stops ticking. In Java Edition, if the cartographer is in the Nether or the End, either spawned or transported, the trades for the map do not unlock. Journeyman-level cartographer villagers sell woodland explorer maps for 14 emeralds and a compass.
Apprentice-level cartographer villagers sell ocean explorer maps for 13 emeralds and a compass.
