Before we give in freely to the Southern Hemispheroids or those South Southeast whack jobs and start changing the maps and globes of the world I would like add to the discussion on why north should be up on a map, the seasons. If we change the orientation of maps you’re going to need to change the calendar too.
As far as I can tell a majority of cultures current and historic follow the seasons in a progression of Spring to Winter, birth to death. With the major calendars of the world; Gregorian, Chinese and Islamic following this progression. Making the South the top of the globe will just be word play unless the calendars are also changed along the whole way the majority of the world looks at progression of the year.
So I think some part of North may be based historically on the location of principle cities, I think fundamentally it’s based on the calendar/seasons and in the Northern Hemisphere the season follow the calendar in correct progression.
It be interesting to know which came first the calendar or the map. Maybe the whole bias of the progression of the calendar/seasons comes from some caveman mapmaker who just didn’t like southies.
