Self-confessed map addict Mike Parker explores modern cartography.

Mike Parker hits the city streets to find out what makes the ideal map for steering us through the urban jungle. He meets the man who has made it his mission to single-handedly create a new map of Manchester, and discovers how digesting the entire London A to Z makes cabbies' brains bigger.
