Draw all US, Canada and Mexico subdivision borders

Welcome sadists, to an expansion of an earlier torture device.
I do mean ALL borders
The bodies of water used is somewhat arbitrary, if at first you don't succeed, deny you ever tried.

Very nice indeed. I guess this is a spherical projection? That's the best you could do for a continent-sized quiz. It can be disturbing not to have vertical meridians, but I much prefer this to a Mercator projection, especially with a boreal country as Canada.

The design is much cleaner too, all the states are well-drawned. Maybe the lines look a bit too faint, but they are perfect in zoom. The only thing that I could ask for is a wider map (as it is, it stops at about 3/4 of the answer columns' width).

About what seems to be a "four corners" in Mexico, I don't think that's correct. I looked on Google maps, and it seems there is a 1,5km border between Zacatecas and Guanajuato, and no border between Jalisco and San Luis Potosi.

Anyway, this is too well-designed not to be featured.

Cheers! Yeah, I like this a lot more than the Mercator used previously, especially when trying to add Mexico.

For the width, it's actually an issue with the shape of the map. JetPunk limits the size of an svg to 630h x 800w. To make this image as large as possible, it's 630h x 563w. However, the minimum width of the quiz columns is 730, so I haven't seen a way to reconcile the extra 200 px.

As to the Mexican 4 corners... I'm not sure. When I came across it in the SVG, the symmetry of each of the 3 countries having a 4-corners site was so pleasing, I didn't look into it further. Google Maps seems to indicate no border between JC and SLP, but Britannica lists them as bordering each other. I'll look into it further.

Masochist.

I might do that (though at the country level, not the state/province level), but I'd really have to nail down which bodies of water to use. Does Italy, for example, border just the Mediterranean Sea, or does it border the Adriatic, Ionian, Tyrrhenian, and Ligurian? And if Sardinia borders the Tyrrhenian on the east, what does it border on the west, just the Mediterranean? Multiply that by the ~200 countries in the world... would require some thinking.

Complete glutton for punishment here, I'll admit! Badly phrased by me earlier, I also meant on the country level rather than state/provision/ sub-division level. Raises so many interesting questions - I like how islands would be included in a 'borders' quiz as you'd have to include e.g. Jamaica / Caribbean Sea....

I imagine you'd have to be somewhat arbitrary again, e.g. is the Caspian Sea included? I think probably for sanity/ size of quiz it would be Italy as just the Med rather than all of those individual sub-divisions of it, but an interesting dilemma to have!

And then you get into the business of all the overseas territories, which create borders between Seas and Countries halfway around the world... (looking at you Pitcairn... and Reunion.. and about half of the Caribbean...)

Oh, and Antarctica. Is it a 'border' if the claimed territories overlap? And what about the areas no country has claimed, does New Zealand border "Terra Nullius" down there? Maybe I should just ignore Antarctica since everyone else does. But by that logic, I should ignore New Zealand, so...

+2
Level 55
Aug 25, 2021
All great points! For what it's worth, I'd ignore Antarctica, but include almost everything else! France bordering Netherlands on Saint Martin / Sint Maarten, Spain bordering Morocco, UK bordering Gibraltar etc. - all would be fair game.

Now I'm starting to think how many seas/coastlines the UK would technically border and my head is starting to hurt!

Aug 25, 2021
All right, so I started building this map. I'm breaking down the countries in alphabetical order, and am now up to Ireland, so the UK is still a ways off. Indonesia nearly killed me deciding which seas/straits/bays/gulfs to include and which to blend into a larger body. Walking a tightrope between what's remotely possible and torturing you for putting this idea into my head...

Frustrated I only saw this today! Luckily I know you'll be somewhere in the middle of this mad, mad endeavour. If it helps with motivation, part of your arbritary decision making and 'deal with it' attitude is my favourite thing about your quizzes and maps!

Apologies for putting this insane idea in your head but I can't wait to see what comes out of it...

Interesting, I'm not solid on Mexican geography (part of the reason I made this quiz). The map I worked off of had San Luis Potosi bordering Coahuila, and thus the two of them separating Zacatecas and Nuevo Leon, but Google Maps disagrees. It's on my to do list now!

Not quite as annoying as you might think. Basically using Excel, just perfect the type in for each individual state/province/body of water, then use concatenation to assemble them into one large regex for each answer which allows them to be entered in any order, and include that regex as part of the answer import.

Love the quiz. A couple suggestions around the Canadian borders:

1. Manitoba/Nunavut/Saskatchewan/NWT form a four-corners scenario like the one between Colorado/Utah/NM/Arizona.

2. Include James Bay (the one sticking out the bottom of Hudson Bay).

If you're going to say the quiz really does ask *all* first-level subdivision borders, you really ought to include the US territories. Not including them is a reasonable decision, but warrants a note to that effect imo. I did spend a minute trying a few of them to no avail.

Also I'm not entirely sold on including Lake St Clair and not Lake of the Woods or Lake Champlain. The Great Lakes seem fair game, but I question whether St Clair is really the next most important lake.

Also also for some reason my brain refused to actually type all the four-corners borders, it just went "yes that's a 4-corners", moved on to the next thing, and never came back. grr.
