Wolfgang Baur was talking about zooming into Anna's map on that show. I guess he meant on this website.
Here is the blurb on the website:
The zoom is fairly interesting. You can zoom out until Midgard is a smallish rectangle surrounded by blackness. That might be for future use, when they get Anna Meyer to add more maps to the north, south, east and west.midgardmap.koboldpress.com wrote:Welcome to the interactive Midgard Map. Use the filter and navigation list below to quickly find a location.
Please be aware that this is an initial, beta version and support on mobile devices or smaller screens is not guaranteed. To clear all markers, refresh the map.
The marker feature is quite interesting too. You can type the name of a Midgard place and zoom into it. Then drop a marker, and type another place, zoom to that and drop a second marker. Then you can zoom out and see where they are relative to each other. This feature could be good if you have a group of players who have been moving across the surface of Midgard and wanted to show all the places they have visited, so that your players could visualise the route.
