    IRL, I'm at 14th parallel north, where would I be in the tilted Earths in this thread?

    Gotta have the longitude as well. Also, far likelier to find it if you look for it yourself. :)

    OK, so I created my own tilted Earth. Its North Pole is at 70th parallel south and 179th meridian west in real life. [​IMG]

    One tilt that I haven't see is basically the North Pole somewhere in OTL Central Asia, say at Alma Ata, Kazakhstan.

    Wait, if you put the North Pole in a certain place, would places that are above/below it IRL also be in the North Pole?

    Any prgress on the project of mapping Lyr, @Tangle ?

    If you put the north pole in a certain place, every horizontal direction is south of that. If the north pole is in Manhattan, the Bronx is south, Brooklyn is south, queens is south, Jersey city is south, long island is south, and so on. Going up and down in an elevator, though, is no compass direction at all. It's still north pole.

    To figure out your latitude, determine your distance from the new north pole and divide by ~110 km, then subtract it from 90. Finding longitude requires you to designate a prime meridian.

    How about my longitude?

    My new altered Earth. Its North Pole is at 12.6, -8 in real life: [​IMG]

    Is there a formula for longitude?

    None.

    You can literally pick a number between -180 and +180. Meridians can't be preserved when the axis is changed, and the location of the 0° meridian is inherently arbitrary, so there's no real meaning to the value of longitude. Climate, as well, is mostly dependent on latitude and the specific arrangement of land and sea.

    If you want the longitudinal difference between two arbitrary non-polar points on the Earth, that would require vector algebra, which I am terrible at. A formula is given here, but making it specific it to the latitude-longitude system will require some work.

    One last change. (North Pole is at 22, -11 in real life.)

    Has anyone ever done a scenario where Europe is at one of the poles?

    In which nations/coordinates are the North Poles of these two maps? I would love to know, but I can't do much with "22/-11"...
