Imagine that you are visiting a city for the first time. How
would you find the places you want to visit? You might ask
a local person for help, or you might look at a map of the
city. In previous grades, you learnt a little about maps, and
in this chapter, we will study them in more detail.
Let us play a game. Examine the map of this small city
(Fig. 1.1). Imagine that you just got off a train at the railway
station, and you want to visit the bank marked on the
map. Which way would you go? Are there other possible
ways? Can you locate the public garden, the school and
the museum? If you want to proceed from the bank to the
market, which way will you go? This is where a map comes
in handy!
A map is like a treasure guide; it shows you where things
are and how to get to them. Notice the four arrows in the top
right corner of the map; we will soon see how they point to
some specific directions and make maps even more helpful.

3. Which is farther away from the railway station —

A Map and Its Components
From this simple example, we understand that a map is a
representation, or a drawing, of some area — it may be a
small area (a village, a town, etc.), a bigger area (say, your
district or state), or a very large area like India or even the
whole world. In a map, you look at the surface as if you are
viewing it from the top.
An atlas is a book or collection of maps.
As you will discover, there are several kinds of maps —
? physical maps, which mainly show some natural
features such as mountains, oceans and rivers (see an
example in Fig. 5.2 in this textbook)
? political maps, which show details of countries or
states, boundaries, cities, etc. (for instance, a map of
India with all its States, Union Territories and their
capitals)
? thematic maps, with a specific kind of information
(examples include Fig. 6.3 and Fig. 8.1 in this textbook).
In addition, there are three important components of
maps—distance, direction and symbols. You have already

experienced the first two while navigating the map in Fig.
1.1. Let us now define them more precisely.
Have you ever wondered how a huge place can fit on a small
piece of paper? It is all thanks to the map’s scale. Let us go
back to our map of a small city (Fig. 1.1). Each centimetre
on the map, as printed here, represents a certain distance
on the ground — let us suppose it is 500 metres; we say that
the scale is 1 cm = 500 m. Now, turn to the map of India in
Fig. 5.2 in Chapter 5 of this textbook. The scale is repre-
sented in the bottom left corner by a ruler with ‘500’ written
above its length and ‘km’ on the side. It simply means that
this ruler, which measures 2.5 cm in the printed map,
corresponds to 500 kilometres on the ground.
So, the actual distance between two points represented on
the map depends on the scale that the map is using.
LET’S EXPLORE
Æ Draw a simple map of a school’s playground. Let us
assume it is a rectangle, 40 m in length and 30 m in width.
Draw it precisely with your ruler on a scale of 1 cm = 10 m.
Æ Now measure the diagonal of the rectangle. How many
centimetres do you get? Using the scale, calculate the real
length of the playground’s diagonal, in metres.
Let us return to the four arrows at the top right
of the small city’s map. They point to four
directions, which are north, at the top, and,
moving clockwise, east, south and west.
These are called the cardinal directions,
also cardinal points. Other than these,
intermediate directions are also used —
northeast (NE), southeast (SE), southwest
(SW) and northwest (NW). Most maps
simply have an arrow marked with the
letter ‘N’, which points to the north direction.

Æ Consider the map of the small city again. Identify the
correct and incorrect statements in the list below:
1. The market is north of the hospital.
2. The museum is southeast of the bank.
3. The railway station is northwest of the hospital.
4. The lake is northwest of the apartment blocks.
Æ Taking your school as the starting point, do you know
approximately in which cardinal direction your home is
located? Discuss with your teacher and your parents.
Symbols are another important component of maps. Our
map has small drawings of actual buildings and a few
other elements, but there would not be enough space on the
map of a large city or a country to draw them all. Instead,
a symbol is used to represent these features — symbols for
different kinds of buildings (for instance a railway station,
a school, a post office), for roads and railway lines, and for
natural elements such as a river, a pond or a forest. In that
way, numerous details can be shown in the limited space
available on a map.
To make maps more easily understood by a variety of users,
map makers use specific symbols. Different countries use
different sets of symbols. The Survey of India, a government
body, has fixed a set of symbols for maps of India (or parts
of India). A small selection of them is shown in Fig. 1.2 on
page 12.
LET’S EXPLORE
Draw a rough map of your locality or your village, including
your home, school and a few other important landmarks. Show
the cardinal directions and use a few of the symbols shown in
Fig. 1.2 on page 12 to mark some important features.
