A map is a representation or a drawing of the earth’s surface or a part of it drawn on a flat surface according to a scale. We find that maps are useful to us for various purposes. Maps can be used to show the physical features of the Earth (mountains, plains,oceans, rivers, etc.), the political divisions of the Earth (countries, states, cities,villages, etc.), and certain specific information (roads, rainfall, forests, industries,etc.) It can be used for representing large areas like continents or countries (large scale maps), and also for representing a small area like a village or a town (small scale maps).
