In Civilization III, the discovery of the technological advance Satellites reveals the entire world to the player, however in pretty much any game I've ever played, World and territory maps are cheap (if you aren't at war with a civ, you can trade for them for less money than building most military units). So as a result of this, the occasional sea square bordered by the ice at the top and bottom of the map may be revealed but rarely anything else.
How do we get the discovery of Satellites in our world to actually reveal areas?
This would involve a civilization that is so insular that information as to where mountain ranges and rivers within their territory exist is something that they could manage to keep from foreigners for hundreds of years. Pre-Peary Japan would seem like an open civilization...
Ideas? (Antarctica doesn't count, unless it is Green Antarctica.)
