Which map projection is very useful for navigational purposes? Explain the properties and limitations of this projection

The Mercators projection is very useful for the navigational purposes. The properties and limitations are as under :

Properties :

1. Parallels and meridians are straight lines. They intersect at right angles.

2. The distance between meridians remains equal whereas distance of parallels go on increasing towards the pole.

3. All parallels are of the same length.

4. The scale along the equator is correct as the length of equator is equal to the length.

5. The meridians are longer than the meridians on the globe.

6. The shape of country is represented truly at every point as parallels and meridians intersect each other.

7. The projection is orthomorphic.

Limitations :

1. The scale along the poles and meridians increases rapidly towards the poles.

2. Poles in this projection cannot be shown.
