From the Moon - Episode 4 - Mapping the Uncharted

The fourth episode of season 2 of From the Moon looks at a vital part of knowledge when it comes to understanding both the surface of our own planet, or indeed any part of the universe. From the Mississippi Delta in Louisiana to an icy moon of the distant planet Saturn, the episode goes to see how geography and design, as well as art and science fuse to create the maps we often take for granted.
