Self-confessed map addict Mike Parker continues his exploration of modern cartography.

Mike considers the picture that maps and atlases give us of the wider world and our place in it.

He discovers how cartographers always have to keep one eye on the map and the other on the news as territorial disputes rage, borders change and new countries emerge.

And he visits Jan Morris to look through a collection of maps and atlases accumulated over 60 years of travel writing.
