For a plot, there are 4 principal directions, otherwise called cardinal directions and another four are auxiliary intercardinal, or ordinal directions.
Principle Directions?
The principal directions are East, West, North, and South. The principal directions are also called cardinal directions.
Auxiliary Directions?
The auxiliary directions are Northeast, Southwest, Southeast, and Northwest. Auxiliary directions are also called Ordinal directions. Each auxiliary direction consists of equal two half sub-auxiliary directions, thus the two half of the Northeast direction are Northern Northeast and Eastern Northeast. The portion immediately after the North is the North-Northeast direction and immediately after the East direction is the Eastern Southeast, likewise, this method applies to all other intercardinal directions.
