South Korea is infamous for its unusual map.
Korean law requires map data to be kept within their borders, and Google doesn't want to keep all Korea-related Maps services on Korean servers.
Instead, Google purchased prerendered images sometime many years ago.
That's why road numbers are so hard to find on the map, and also why many locations are a bit misplaced, and why movement can be awkward: the street view pictures can't be related to the roads on the map, but instead Google guesses where the roads are based on its GPS data.
The aim of this site is to provide both a tutorial-style guide to playing Korea, and reference material.
For now I'm just collecting reference material that I can then use in the guide :)
The poles at subway exits are some of the most useful things you can find in urban locations in Korea.
The poles list the name of the station, the colour of the lines serviced by that station, and the exit number.
Different cities use different styles for their subway exits.
