this is amazing - I'm a map geek and this stuff is catnip for me.

I built a, for the time, very good data logging setup for my Jeep and mapped some trails[0] in 2001. Why? The maps provided by the USFS and the timber leaseholders were (and still are) wrong.

I also made a point the first time I was in Europe of renting a car and driving to Baarle-Hertog[1] and walking to all of the enclaves, as well as enclaves within enclaves.

I live somewhat near Baarle-Hertog. Normally, there's no real issues with the enclaves, since both Belgium and the Netherlands are in the EU. But the coronavirus has caused national policy to differ, with the funniest example being: shops in Belgium were (some have since been allowed to reopene) forced to close, but the ones in the Netherlands weren't, leading to bizarre situations where shops that crossed over the border (sometimes multiple times) had to 'close' the parts located in Belgium, but not the one in the Netherlands. So you would not be able to buy things located in the 'Belgian area'. Crazy, but cool!

There really are some weird edge cases out there.

E.g. parts of the border between Switzerland and Italy is described by peaks and valleys of the alps. Now due to climate change, glaciers are melting, and suddenly parts of Switzerland and Italy are swapping. [https://www.nzz.ch/panorama/neue-landesgrenze-schweiz-und-it..., German only]

Next project? Enclaves in enclaves in enclaves?

That's an interesting article, and Google Translate does a fine job on the English translation.
