This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

What? The projection matters on any scale and for navigational purposes will continue to use mercator projection on flat maps so there it doesn't matter.
It really doesn't. On a ball as large as the earth, if you take a tiny section of it, it's basically already flat. You don't need to transform it mathematically to make it fit on a grid system.
Maybe you've never seen a map made for land navigation? They don't need to distort terrain feature size to make everything line up directionally.
Can you share one or the name of the projection used? I am having an harf time searching for it
Edit: i found that for air navigation they use Lambert Conformal Conic, for marine they use Mercator and for land i found nothing which makes sense (and probably it would be Mercator anyway)
