Every map consists of a vertical line (arrow) at the upper right hand corner of the map where ‘N’ is marked to indicate the north. This line is called the North Line. There are four cardinal or main directions. These are known as the cardinal points. The directions are North (N), South (S), East (E) and West (W). Amidst there are four intermediate directions. They are North-East (NE), South-East (SE), North-West (NW) and South-West (SW). If the map does not depict the north line then the top of the map is considered as north.
