Map is a two – dimensional representation of the world or some part of it. Like a globe, a map is not a model of the earth and hence when representing three dimensional things on a two dimensional surface, some mistakes occur. There are chances of variation in the size, shape and direction on a map. For example, the size of latitudes decreases while moving from the Equator towards the poles in a globe, but on maps, they are generally of the same size. This gives rise to change in shape and size of the countries lying on higher latitudes.
On the globes, the poles are almost equal to a dot, but on maximum maps, they are shown by a single straight line. In spite of that, the maps have special advantages of their own. They can be easily drawn. They can be carried and handled easily. Small villages, cities etc. can also be represented in a map. Along with this, various types of maps can be made according to the requirement and various types of information can be obtained through them.
