Age of Empires Series Wiki

Cartography is a technology in Age of Empires II available at the Market. Once researched, it grants the player their shared allies' Line of Sight (LOS).

Cartography is a very helpful technology in the early part of the game, especially when allied with computer players. Players wishing to see the Line of Sight of their enemies will have to research Spies, but this is only available in the Imperial Age and quite costly.

With patch 5.7, Cartography was removed and ally LOS is automatically shared once the first Market is built (or right at the start of a match if a member of the team is Portuguese).

There was a revival of European learning after the Dark Ages that started mainly in the monasteries of the Christian Church, particularly in Ireland. The west Europeans were far behind the educational standards of the Byzantines, the Saracens, and the Chinese. Part of this revival was an interest in geography that became even more pronounced when the Crusaders and adventurers brought back tales of exotic trade goods and riches beyond the horizon. Kings and churchmen commissioned maps and cartography, the science of map making, became a newly prized skill.
