It's because there's a ton of absolutely stellar lectures and discussions by professional historians freely available on Youtube. If you know who the leading names in whichever field or time period that interests you are, Youtube is a great way to get content that's far, far more in-depth than anything you will get even from the best made TV documentaries. You can get unadulterated Glantz, Browning, Tooze, Kotkin, etc., all just a search away. Find yourself a youtube to mp3 converter online and you can get yourself a load of podcasts as well. Obviously this doesn't work for image intensive lectures.

It also bends like crazy and accidentally puts riverine islands half-way into the States/Canada, but it's very literally marked out.

sullat posted:I did not realize that the border was attached to the stone, like some bureaucratic ley line. VERY broadly speaking property boundaries are laid out on the ground, generally with natural features or monumentation (like that stone), then the boundaries are described in a legal document like a land plat which is somehow approved and accepted by the relevant government agency. (I am not 100% sure if this is the way international borders work, but this is how all property in the USA, Canada, and the UK works. I suspect there's a similar system in place here.) Moving the stone won't really move the border as it is specified in the legal description, but it will make things confusing and annoying if anyone ever needs to check it for any reason. ("The legal says the monument should be here, but it's over there, WTF.") My job involves land survey work, I can talk all day long about this is you like.

No, European borders are actually physically tied to border stones. This has led to occasional problems, like one time a Japanese tourist took a stone as a souvenir and now part of the Hungary-Romanian border extends to Hokkaido.

In tl;dr terms - when you buy a piece of property you either accept a prior survey or have it resurveyed. Land surveyors come out to the property and measure it to make sure it is laid out as it is described on the deed. This is the "legal description;" it describes the location and the boundaries of the property. This is kept with/is part of the deed and is filed with a government agency, like a county clerk. This is what a legal description looks like:  In brief, what it's saying is "start at this defined place, then go to the property, then go around it to make a polygon of the boundary." (There's more to a real one, but you get the idea.) If someone went out and moved the fence around the property it would not change where the property is, because the fence would no longer agree with the legal description. The property owner would have to go move the fence back to comply with the legal. I find it hard to believe that there isn't some sort of legal or treaty or boundary agreement between France and Belgium that describes the placement of the monuments but is in fact the legal agreement between the two nations. A few posts ago the US/Canada border was mentioned. There's an agency, the International Boundary Commission, that maintains the border. This border also uses monuments - like the French/Belgian one - but the placement of the monuments is defined by the "International Treaty" (of 1908) which includes (in an appendix) a legal description of the monuments. If a monument was moved, they'd move it back to comply with the treaty, but the border itself would not move.

iv46vi posted:Does the modern GPS not have enough resolution to be useful as a replacement for boundary descriptions? Yes, until Kessler effect actuates. Regarding historic border treaties, sometimes the details were, shall we say, sketchy. Such as the first treaty between Sweden and Novgorod: quote:The original text of the treaty has been lost. It has survived in partial copies in Russian, Swedish, and Latin, which are somewhat conflicting.[9]  Red line is the part of the border that we know for sure. North of this everything was wilderness with few people who didn't give a toss about borders. Except over time more people would settle there to avoid heavy taxation in the more central areas, making the wilderness region more attractive to the kings of Sweden, leading to new conflicts!

So it’s not very useful for defining borders in the middle of nowhere. Exactly. And as such, you're still using the "old" system. You start at a monument (that "fixed and well defined reference point") then use bearings and distances to go to the property, then describe the property. Fangz posted:Aren't there national borders that are defined by, e.g. rivers, though? What happens when the river moves? Again, you go to the legal description. That's what defines the border, not the river. If the river moves, the legal description still defines the border unless you renegotiate and re survey the border, which doesn't always happen. There are plenty of borders between US States where the river has shifted - the legal still defines the border even though the river moved:

Presumably the old river bed also continues to exist so you still have a natural geographic reference. Due to land rising the Kvarken between Sweden and Finland will become a land bridge in the next 2000 years, isolating the northernmost gulf of Baltic Sea into a lake. This shouldn't be a problem from border treaty POV, assuming that same borders still applied in a.d. 4000 which is rather doubtful.

That sounds like it's going multiple millimetres a year. e: it's only 25m deep apparently, but still, that's a hefty rate of movement for a bit of sea bottom. e: quote:In 2006, parts of the Kvarken Archipelago were added as an extension to the World Heritage Site of the High Coast (located on the western shore of the Gulf of Bothnia) in Sweden, because it is “continuously rising from the sea in a process of rapid glacio-isostatic uplift, whereby the land, previously weighed down under the weight of a glacier, lifts at rates that are among the highest in the world. As a consequence of the advancing shoreline, islands appear and unite, peninsulas expand, lakes evolve from bays and develop into marshes and peat fens. This property is essentially a ‘type area’ for research on isostasy; the phenomenon having been first recognized and studied here.”[2] Most Finnish parts of the High Coast/Kvarken Archipelago World Heritage Site are situated in the Korsholm municipality.

It is widely used for boundary surveying, particularly in remote areas, but it's not a replacement. In particular because cm level positioning is differential, it's typically done with RTK, with your base station over a known point in the cadastral network.

Also, GPS is defined relative to a fixed model, so your property will shift slightly relative to it's "actual" boundaries due to continental drift (between 3 and 0.5 inches/year depending on plate - it's fastest in Australia, apparently) and other earth-moving experiences (https://darksky2500.medium.com/hollister-58b77e02facb). https://gis.stackexchange.com/questions/137192/does-gps-correct-for-continental-drift looks like it might lead to some more detail if you still care.

While that's true, the actual drifts of the continents relative to WGS84 are extremely well understood and it's mathematically straightforward (the biggest problem normally is figuring out what datum various input positions were in to begin with) to convert from the global datum to a local plate fixed one. For real time applications that's normally resolved by using differential corrections from a base station nearby, but it can also be done without a local base. That said, this is all extremely non-Milhist at this point, so come ask more questions in the GPS Megathread PittTheElder fucked around with this message at 19:52 on May 5, 2021 |

re: borders I'm going to go full grad student and say that they are cultural constructs. The only reason I'm mentioning this is that once in a while it's important to sit back and think about what, exactly, the phrase "cultural construct" means. It doesn't mean that it's bullshit, or unimportant. Tons of things that are insanely important to people's day to day lived experiences are cultural constructs. Gender and race to name two obvious hot button issues. But what it means is that there isn't some natural, immutable property that defines it. It is whatever we all agree that it is. The beaver and bears and moose don't know or care what the gently caress the Canada - US border is. But if you're a human? That poo poo's important because of the cultural context of things like taxes and laws and import regulations etc. Which is all to say that borders are inherently arbitrary and exist only as a mutually agreed upon delineation of where one sovereign's (or government's in a post french revolution era) regulations end and another's' begin. The only reason upstate New York is New York and not Ontario or Quebec is because of a few centuries of history and culture that culminate in Tim Hortons only being in one place and not another. All of which tl;dr's down to the location of a specific rock marking where one person's patch begins and another's ends being both incredibly meaningless and profoundly, incredibly important and worth fighting wars over. Welcome to history, people are complex and irrational and that isn't good or bad it's just a thing.
