15 Minute Maps

by Hugo Powell

This podcast is dedicated to those people making positive change in the world using GIS, mapping and cartography. Each guest is given 15 minutes to describe their dream map, and how it could impact the work they do. Hello and welcome to 15 Minute maps, where I ask my guests to let their minds roam free and come up with a new idea for their dream map. The first known map of the world was created three thousand years ago, (of a flat disc-like world surrounded by water,)  and today we are making maps of the furthest reaches of the known universe. In between lie a myriad of mapping possibilities. What if we could do away with resource limitations… think beyond the conventions of time, space and political boundaries? What new kinds of map could we dream up?
