How many types of map and where its used

A globe can be useful when we want to study the earth as a whole. But, when we want to study only a part of the earth, as about our country, states, districts, towns and villages, it is of little help. In such a situation we use maps.

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. But it is impossible to flatten a round shape completely. We find that maps are useful to us for various purposes. One map shows a small area and a few facts. Another map may contain as many facts as a big book. When many maps are put together we get an Atlas. Atlases are of various sizes, measurements drawn on different scales.

Maps provide more information than a globe. They are of different types. Some of them are described below.

Physical maps

Maps showing natural features of the earth such as mountains, plateaus, plains, rivers, oceans etc. are called physical or relief maps.

Political maps


Maps showing cities, towns and villages, and different countries and states of the world with their boundaries are called political maps.

Thematic Maps

Some maps focus on specific information; such as road maps, rainfall maps, maps showing distribution of forests, industries etc. are known as thematic maps. Suitable titles are given on the basis of information provided in these maps.There are three Components of Maps – Distance, Direction and Symbol.

Sketch

A sketch is a drawing mainly based on memory and spot observation and not to scale. Sometimes a rough drawing is required of an area to tell where a particular place is located with respect to other places. Suppose, you want to go to your friend’s house, but you don’t know the way. Your friend may make a rough drawing to show the way to his house. Such a rough drawing is drawn without scale, and is called a sketch map.

Plan

A plan is a drawing of a small area on a large scale. A large-scale map gives lot of information, but there are certain things which we may sometimes want to know for example the length and breadth of a room, which can’t be shown in a map. At that time, we can refer drawings drawn to scale called a plan.
