Trusting Maps and GPS Failures

Last year, Americans spent more than 300 billion minutes on navigation apps, like Waze or Google Maps.

The GPS systems in our pockets have come a long way from the first known map, carved into a mammoth tusk 30,000 years ago.

But even with satellites tracking us and the ever-changing Earth from the skies – digital maps aren’t fact. Errors can show up and are sometimes as old as maps themselves. The phantom island of Sandy Island appeared on Google Maps until 2012, when Australian scientists sailed to its supposed location and found only open ocean.

Mistakes on maps were sometimes intentional, sometimes not – but every single one tells a bigger story.

How and why did it get there? What does it reveal about the creator of the map and the world around them?

We sit down with Jay Foreman and Mark Cooper-Jones, better known as the Map Men on YouTube, to talk through these questions and more.
