This only came to my attention today: Under the moniker “swisstopo historic”, swisstopo produces a podcast about the history of cartography and geoinformation, as well as other content such as blog posts, coverage in the media and “scrollytelling” stories (for example, this one).
The podcast is now in its fourth season, with the following themes per season:
- Season 1: Water on historic maps
- Season 2: Human and mechanical computers
- Season 3: Names on maps
- Season 4: National boundary
As far as I have seen, the podcast episodes are in (standard) German, also the one about standard French and Patois.
