If a picture paints a thousand words, a map can paint a million. They help us navigate our way through unfamiliar landscapes and cities, entice us into new places and give us a bigger picture of the world we inhabit.

Self-confessed map addict Mike Parker explores modern cartography navigating his way over ten episodes.

He begins with the maps he first fell in love with as a teenager - Ordnance Survey maps.
