Inspired by a comment by [email protected] under SurrealPartisan’s recent post in this community
The longest straight line over land is this great circle (see NeatNit’s comment here if the link isn’t working for you, sorry about that). But, of course, most great circles don’t look very straight on most maps. To correct for this, I (very roughly) got the northernmost point of the great circle and put that value into G.Projector to get an oblique equirectangular projection that treats the great circle as if it were the equator on a regular map
The base map is Wikimedia Commons’ equirectangular projection map
Quick, someone tell geowizard !No one tell geowizard anything, please.
Used to really like his videos, then I found out he’s a Reform UK voter because he doesn’t like immigration and yeah, never unsubbed faster
Oh for fuck’s sake. I liked them too
My exact reaction, so disappointed

Some quotes from him in here

In particular this bit which is just straight out of the Great Replacement Theory playbook “Think about it. Either there would be civil war, or the British culture and values that we hold so dear; freedom of speech, fairness, justice along with all the other stuff we cherish; our music, sense of humor, pubs, Christmas, etc would eventually disappear and be replaced with other ideals”
Oh wow, I had no idea…. Unsub from me as well, thanks for the info!
Great example of how a straight line on our round marble is not a straight line on our marcator projection maps and vice versa.
Your great circle link doesn’t work for me. It goes to a page with the title “Fix location 5�2′51.59″N 9�7′23.26″W” and the red error message “No locations match 5�2’51.59"N 9�7’23.26"W”. I think that site is quite broken, which isn’t too surprising considering it doesn’t even support HTTPS.
Edit: this is apparently Lemmy breaking links. I reported it: https://github.com/LemmyNet/lemmy/issues/6613
Managed to work it out, here’s the fixed link:
www.gcmap.com/mapui?P=5%B02%2751.59%22N+9%B07%2723.26%22W-28%B017%277.68%22N+121%B038%2717.31%22E&MS=wls&DU=miApparently Lemmy is screwing something up with the link. If you paste it into a comment, it gets modified.
Edit: okay, what the hell.
The query string starts with:
P=5%B02%27But this gets converted to:
http://example.com/?P=5%EF%BF%BD2%27Ahh, if it’s an issue with lemmy then that would explain why it’s working for me. I’ll add that as an alternative link in the post body
yeah I’m still playing with it, seems like a really serious lemmy bug. I’ll report it.
Ahh, sorry about that! I took the link from the reference on the wikipedia page where I found it. The description is:
The longest continuous straight-line (great circle) path over land is 13,588 km (8,443 mi) long and spans between the West African coast near Greenville, Liberia (5°2′51.59″N 9°7′23.26″W) and a peninsula about 100 km (60 mi) northeast of Wenzhou, China (28°17′7.68″N 121°38′17.31″E), passing over the Suez Canal.
So yeah, as I found out this was entirely not your fault. Lemmy literally doesn’t let you post the correct link.
There is a chance that this will work though: www.gcmap.com/mapui?P=5�2'51.59"N+9�7'23.26"W-28�17'7.68"N+121�38'17.31"E&MS=wls&DU=mi
Otherwise, follow these instructions:
Go to http://www.gcmap.com/mapui
Into the “Paths” textbox, paste this:
5°2'51.59"N 9°7'23.26"W-28°17'7.68"N 121°38'17.31"EClick “Draw Map”
Result:
Thank you for your investigations! I’ve updated the post to just point people towards this comment if the link isn’t working
If your map is warped, everything can be a straight line.
The fun part of this one is that it would actually be a straight line along the Earth’s surface if you felt like walking for the 13,000+ km
