Today we use maps with an ease. Google Maps or other such programs allow us to find directions to any place and virtually anywhere at the tap of a finger. Using Google Earth we can fly above the world and explore our world's coastlines and mountains or even the still waves of the open ocean's vast kilometres. The accuracy of these maps would have astonished someone even twenty years ago – let alone a visitor from the pre-digital age. Maps are more than just a set of directions or a hunt for accuracy. They are forms of communication as much as writing. Today we look at maps and the worlds they create for us.
