directions and how to identify them and illustrative diagram

Answer 1

 Can you tell us what *kind* of directions? Are you asking about north/wets/south/east on a map? Directions for a recipe in the kitchen? Instructions for doing something in a factory? Verbal directions for getting from point A to point B?

Answer 2

In a illustrative diagram direction will be use for identify any locations. North, east, south, west directions will be used for remembering any locations or identify them.

By direction we have to identify any locations because direction also describes any movement, like left, right. In a illustrative diagram these direction also used for identity.
