Why do we show ONLY North orientation in maps and drawings, than any other?

Answer 1

When we draw a map we need some reference point, it could be any one of four, SINCE THE COMPASS SHOWS THE NORTH DIRECTION THEREFORE WE USE IT AS A REFERENCE POINT. It is a reference point naturally too.

Answer 2

Because it is the standard for maps. Basically it simplifies everything. If some maps were East orientation, some were West, some South East, etc, then it could get quite confusing. By having them all Northern orientation a person doesn't even necessarily need a marker on the map to tell them what each direction is. As for why North was picked over the other directions: The North orientation comes from the compass being invented in the Northern Hemisphere and there being a greater percentage of the World's population in the North. If the compass had been invented in the South and the South had a larger population then I'm sure all maps now days would have a South orientation.

Answer 3

I think this is only a matter of convention. It may have become convention because the compass needle always points to the magnetic north (and not to any of the other directions).

Also, based on this convention, rules of thumb have developed, for instance, at night in the northern hemisphere Polaris or the North Star indicates where north is. There is no such indication in the night sky for east or west. Yes, when there is a moon it rises in the east and sets in the west generally, but this changes some amount with the seasons and with your position on the globe, plus you could not tell direction by observing the moon for an instant (you would have to follow its path to approximate where east and west are).

Answer 4

Tradition and pragmatism. (It is easier to draw one fancy line than four at precise angles and proportions). Since you are pointing North, you are actually pointing South as well, East and West are perpendicular and thus easily deduced. . .
Besides when you are in the field, you put a compass over the 'Rose' (that is what it is called) so you only need one point of orientation to align the needle and that is North.

Answer 5

All you really need is one point of reference and you can infer the rest of the directions.

Answer 6

Because of the compass.

Answer 7

That is what every body agree to.
