SUB –TOPIC : COMPONENTS OF MAP
1.DISTANCE:
Maps are two-dimensional drawings. It reduces the entire world or a part
of the world on a small sheet of paper. While making a map,
cartographers pay attention to properly represent the distance between
two places. This helps us in finding the actual distance between two
places.
A suitable scale is used for this purpose.
For example of distance between Delhi and Patna; which is about 1000
km. On a map, this may be shown by a ten centimeter long line. In that
case, one centimeter on the map represents 100 km. So, the scale of the
map is 1 cm = 100 km.
There are two types of scales to be used for this purpose.
1)Small Scale Map: When a large area is shown on a small map, such a map is
called a small scale map. Example; map of a country or state.
2)Large Scale Map: When a small area such as a village is shown on a map,
such a map is called a large scale map. A map of a neighbourhood is another
example of large scale map. A large scale map gives more details compared to
a small scale map
2.DIRECTION:
most of the maps, you will usually see an upward arrow and the letter
‘N’. This shows the north direction.
Once we know the north, we can easily find the other directions. North,
South, East and West are the four major directions. These are called
Cardinal Directions.
Some maps also show the intermediate directions, viz. north-east,
south-east, south-west and north-west.
Compass: Compass is very useful for finding directions at a place. This is a
small circular box with a magnetic needle inside. The needle of the compass
always points in the north-south direction. Compass has been used by
