In this episode, Ed Parsons, digital geographer and geospatial wizard at Google, traces the history of digital mapping. He leads Jerry from its roots in Gerard Mercator’s iconic map projection, to the Google Maps we use today – and beyond….
 
Ed’s chosen map is the “Christian Knight” map, produced in Amsterdam by Jodocus Hondius in 1597. It is the first map to use Mercator’s projection after his death. The projection was hugely influential because it changed the way maps were drawn - but the Christian Knight map is also significant for another reason: it is a great example of maps that were created as propaganda.
 
Together, Ed and Jerry tease out why maps are made, and what purposes they serve. Who is each map meant for, and what does that mean? A Protestant map in 16th century Europe could be a rallying cry for a monarch; and a digital road map in the 20th century could transform how journeys are conceived of, and taken. But will maps always be needed – and are humans always the target audience? Tune in to find out!
