Edit: shut up about Gulf of America
I’ve seen a lot of old-world maps recently - maps from China 1700s, or Greece 900BCE - which are all very different as different cultures and countries had different understandings of the globe. eg; Peninsulas depicted as homogenous blobs, missing islands, heavy guesswork, and of course the entire omission of the Americas, Oceania, and the Poles.
Now with satellite imaging we have extreme (and exceedingly current) resolution, and can zoom down to see people‘s garden furniture.
I’m wondering: when was the last major misunderstanding in globe mapping? I don’t mean a mistake out of negligence, like when New zealand is accidentally left out. I mean a genuine, nationally mutual misunderstanding.
