BBC Radio 4 Extra - Mapping the Void

Dr Kat Arney meets a new generation of virtual cartographers, making maps to save lives.

4 Extra Debut. Dr Kat Arney meets a new generation of virtual cartographers, mapping unmapped places and trying to save lives. From 2014.

Dr Kat Arney meets the people trying to change the world one map at a time. These are volunteers who use their free time to map the world's unmapped places and people. 
 
She sees how being on a map affects people's work, education and rights. And in extreme weather or after a natural disaster, she hears how mappers might help us to find the people who have fallen off the maps. She also hears from crisis mappers, people who source any information they can after tragedies to document what is happening on the ground as fast as possible. 
 
This story starts in January 2010, when a huge earthquake hit the island nation of Haiti. Thousands of miles away, a group of American students heard about the damage, logged onto their laptops and started mapping any post-disaster information they could find online. Their aim was to help the rescue and relief services save as many lives as possible.
 
Four years on, international contingents of cartographers now deploy after every natural disaster, and in areas of political unrest and civil war. They scour the internet for cries for help on social media, then mark them on maps to try to get help to people who need it most. 
 
There's also a project making a continual effort to make the most accurate physical map of the globe. Contributing could mean joining a mapping party in London. Or cycling around rural Uganda with a GPS device.
 
Thousands of volunteers are now spending their spare time contributing to these efforts. Some of those who started it all have become internationally recognised in a new area of expertise. As volunteers assemble around the world, Dr Kat Arney asks how powerful these maps can be and also assesses the problems that come with them. 
 
Produced by Clare Salisbury and Jolyon Jenkins.

First broadcast on BBC Radio 4 in January 2014.
