This three-part series tells the epic and beautiful story of cartography, from the discoveries of the early cartographers to the tools that have given us Google Earth and in-car satellite navigation.  Each episode addresses a basic technological challenge of map-making and, in the process, sheds light on the wider world: on issues of power, romance, wars and exploration. In tracing the seismic shifts in the history of map-making and understanding what drove the map-makers themselves, this series ensures that we will never look at a map in the same way again.
