(v) Wall maps are small-scale maps showing large areas. They are useful for students in classrooms and offices. Small scale maps cover a larger area and depict it with limited information.
(vi) Atlas is a collection of maps in a book. Atlas maps are small-scale maps covering large areas like continents and countries.

Maps are a graphical representation of the world or a section of the world. As a representation of the world, maps are compressed versions of the real world meaning that a large piece of land is recreated onto a smaller piece of paper or digital file. The relationship between the real world size of a geographic feature and its representative feature on a map is known as scale. There are three main ways that scale is indicated on a map: graphic (or bar), Verbal and representative fraction (RF).
5.
Elements of maps:
(i) Maps provide us with a lot of information and one must know how to read and interpret them.
(ii) Every map is provided with certain features that act as an aid to study the information presented in it.
(iii) The basic essential elements of a map are title, direction, scale and legend (or) key of symbol.
Title:
Every map has a title that describes the information given in the map. For example, a map with the title India Rivers shows rivers of India.
Direction:
(i) In general maps are drawn with north orientation. It helps us to find other directions on the map like East, West and South. In addition to the North notation, latitudes and longitudes are depicted in the margins.
(ii) The North is notified by letter 'N' with an arrow mark.
Scale:
(i) The scale of a map is the ratio between the distance on the map between two points and actual distance between the two places on the ground.
(ii) The scales can be represented as 1 cm = 10 km.
(iii) It means lcm on the map is equal to 10 km on the ground. It helps to find the distance on the map between two points.
Legend:
(i) A legend or key of a map explains the symbols that are used on it to represent various physical and cultural features.
(ii) The common signs and symbols are internationally accepted and used in maps are called conventional signs and symbols.
(iii) Every map has a legend or a key which explains the different colours and symbols used in it. On a map it is difficult to show the real shapes such as settlements, bridges, post offices, railway lines and forests because there is not enough space to actually draw them.
(iv) They are depicted by using certain colours, symbols or letters.
