Chapter 9 Maps And Scale Salient Points At a Glance
1. Scale is the ratio between the length of two points on the map and the distance between that two points on the ground. A scale of a map can be represented in various forms.
2. A map is a graphic representation of the features of the Earth’s surface as drawn on flat paper, according to a specific scale and on a specific map projection, using internationally accepted signs and symbols.
3. Any map cannot be 100% correct due to the representation of three-dimensional Earth on a two-dimensional plane. Still, efforts are made to draw a map closest to its actuality on a two-dimensional plane.
4. A small-scale map depicts a large area on paper. Wall maps, atlas, etc. are examples of small-scale maps.
5. On a large-scale map a small area is depicted on paper in a larger form. A cadastral map or matza map is an example of a large-scale map.
6. Mauza is the lowest administrative unit in India. Its other name is census village. The scale of a cadastral map or matza map is usually 16 inches to 1 mile.
7. Thematic Map depicts a specific theme or subject on a map. But sometimes a thematic map depicts more than one subject also. If it does so, then certainly the other subjects complement the main one.
8. The conventional signs, symbols and use of colours in a map are explained through an index. That is why the index is called the key of a map. An index may also be labelled as a legend.
9. There are three types of scales that are used in a map. They are—statement scale, fractional scale and graphical scale.
10. Statement scale is a type of map scale expression in which, the relation between the distance of two points on a map and the actual ground distance between those two points is expressed in the form of a written statement.
11. Representative fraction is a type of map scale expression in which, the relation between the distance of two points on a map and the actual ground distance of those two points is expressed in a ratio.
12. A type of map scale expression in which, the relation between the distance of two points on a map and the actual ground distance of those two points is expressed with the help of graphical representation, is known as graphical scale.

Chapter 9 Maps And Scale Topic A Map Long Answer Type Questions
Question 1 Give a brief account of the history of the development of maps.
Answer:
History Of The Development Of Maps:-
A brief account of the history of the development of maps: When the world or a part of it is represented on a flat piece of paper drawn to a specific scale and map projection, using universally accepted conventional signs and some basic principles, it is called a map.
The history of map-making is quite old— about 4000 years. It can be discussed as follows—
According to anthropologists, the maps drawn by the Eskimos, Red Indians, and Marshall Island dwellers are quite old. Charts were made on palm leaves that were attached to narrow frames and shells of snails or fish-bones were used. Straight lines were drawn to denote the sea and curved lines to denote the waves approaching the island.
The people of Babylon were the first to divide a circle into 360 parts. The four cardinal points—north, south, east and west, were also first used by them while drawing maps. The Greeks were experts in Mathematics and Astrology. They were responsible for drawing the lines of the Equator, Tropics of Cancer and Capricorn, and North and South Poles on a spherical world. Eratosthenes was the most well-known person who could draw maps accurately. Herodotus (485 BC – 425 BC) believed that the Earth was round, comprising Asia, Europe and Libya. Ptolemy drew a map of the world as well as 26 regional maps published in his book ‘Geographia’.
Many sailors while exploring different parts of the world, drew maps of newly discovered lands. Columbus was the most famous among them. Ramesses II, the Egyptian Pharaoh, drew a map of his empire for the convenience of tax and revenue collection. The science of map-making (cartography) was thus initiated and it gained much importance at that time.
Question 2 What is a map? Classify the different types of maps.
Answer:
Map:
A map is a graphic representation of the features of the Earth’s surface as drawn on flat paper, according to a specific scale and on a specific map projection, using internationally accepted signs and symbols.
Different types of maps: There are different types of maps on the basis of different aspects.
They are —
1. Classification of maps based on the scale:
1. Small-scale maps: When a map is drawn in a small dimension on a piece of paper, representing a bigger land surface, a small scale is used. These are known as small-scale maps.’
Advantages:
(a) As the scale is small, a bigger area can be represented on a smaller dimension on space or a piece of paper.
(b)The whole world or a part of it can be represented on paper.
Disadvantages:
(a) Various symbols are used to show different components on the map which might not be easily understandable by a layman,
(b) Due to smaller space or dimension, details of the area cannot be shown.
Examples: Wall map, international map, navigation map, etc.
2. Medium-scale maps: When any large area is divided into smaller areas on a medium scale to represent on paper (i.e., a map), it is called a medium-scale map. Example- topographical maps.
3. Large-scale maps: When a small area is shown on a larger dimension, it is known as a large-scale map. Example—cadastral maps.
2. Classification of maps based on utility:
1. General map: When a map can be easily used or understood by the common people, it is known as a general map. Example— district map of West Bengal.
2. Special map: When a map is drawn for any specific purpose, it is known as a special map. Example—physical map of India.
3. Classification of maps based on information or data:
1. Qualitative map: This map shows the qualitative aspect of any geographical feature.
2. Quantitative map: This map shows the quantity-wise variation of geographical features, such as altitude, area, etc. Example—population density map of India, dots and sphere maps, etc.
4. Classification of maps based on topic or theme:
1. Physical map: This type of map shows the physical features of any area. Examples- relief map, climate map, etc.
2. Cultural map: When any cultural aspect is shown on a map, it is called a cultural map. Usually, the socio-economic or political aspects are depicted in such maps. Examples—social map, economic map, etc.
Question 3 Write a note on the contributions of the important cartographers.
Answer:
Note on the contributions of the important cartographers:
The Greek philosopher, Anaximander (610 B-546 BC) was the first to draw a map of a human settlement according to scale. In his map, Greece was shown in the centre of Europe and the land portion of the world was surrounded by seas on all sides.
The Greek philosopher, Eratosthenes (276 BC-194 BC) is known as the ‘Father of Geography’. He was the pioneer in using lines of latitudes and longitudes on accurately drawn maps.
Hecataeus (550 BC-476 BC) slightly modified the map drawn by Anaximander and drew it accurately with more descriptive details. This was a map showing Eurasia.
Herodotus (484 B-425 BC) is known as the ‘Father of History’. He believed that the area of land between the coastal areas of India and Spain was surrounded by seas and oceans. He divided the Earth into Asia, Europe and Libya.
Several other scholars also gave importance to drawing maps. Among them, there can be a mention of the Roman philosopher Strabo (64 BC-24 AD) and Claudius Ptolemy (90 AD- 168 AD). Ptolemy drew about 26 regional maps of different parts of the world.
In the later period, Chinese geographers and scientists drew maps on the basis of grids. Zhang Heng (78 AD-139 AD), Fi Sui (224 AD-271 AD), Chu Su Pin (1273 AD-1337 AD), etc., were well-known for drawing maps. Fi Sui is known as the ‘Father of Map Science’. This person drew the political map of China on a large scale in 276 AD.
In the middle ages, an Arabian geographer Al Idrisi (1099 AD-1161 AD) tried to draw maps as well. In the later period, Columbus, Magellan, James Cook and several other explorers made huge improvements in the methods of map-making.
In modern days, Cartography has hugely digitised with the application of Geographic Information System (GIS) techniques. But, these ancient cartographers are the ones who laid down the foundation of map-making.

2. Climate map: This map is based on climatic features like air pressure, rainfall, wind, cloudiness, etc. E.g., from the
rainfall map of India, we can have an idea of the areas receiving high and low rainfall.
3. Vegetation map: The types of natural vegetation os shown on such a map. E.g., from the natural vegetation map of India, evergreen, deciduous, coniferous forests can be identified.
4. Soil map: it is drawn on the basis of the characteristics of the soil of a region. E.g., the soil map of India reveals that the Gangetic Plain has silt, the Rajasthan region has sand and the Deccan Plateau region has black cotton soil.
5. Others: Space-related topics such as the location of stars and planets and also rock types, drainage basins and other such features on the Earth’s surface are shown on these maps.
2. Cultural map: The cultural aspects like social, political, historical, economic, etc. of a particular region are shown on maps called cultural maps.
1. Social map: The maps drawn on the basis of social aspects such as population distribution, tribal population density, linguistic data etc. are called social maps. E.g. a map is drawn of the different languages spoken in India.
2. Economic map: These maps show the distribution and characteristics of agricultural, mineral, forest, and industrial products. E.g. the mineral map of India shows how the Chota Nagpur Plateau region is rich in minerals.
3. History map: These maps show the historic places of the past, boundaries of the kingdoms and empires, etc. E.g. the expanse of the Mughal Empire shown on the historical map of India.

All the features of a particular geographical region cannot be shown on a map. Hence, only the necessary features (according to the purpose of the map) are shown on it with the help of symbols. These symbols are accepted universally.
Question 24 Why can’t detailed data cannot be shown on small-scale maps?
Answer:
Many details cannot be shown on small-scale maps because—
1. Use of symbols: Since a large area is depicted in a small space, it is not possible to mark each feature with a symbol. Hence small scale maps cannot depict all features, in detail.
2. Complicated topics: Physical, cultural, and economic features (thematic maps) cannot be shown on a small-scale map, and therefore the interpretation of these complicated themes is not possible.

Chapter 9 Map And Scale Topic B Scale Long Answer Type Questions
Question What is map scale? Classify map scales.
Answer:
Map scale:
The ratio of the distance between two points on a map and the actual ground distance between those two points is called map scale. For example, if the distance measured on the map is1 cm and that on the ground is 5 km,
the map scale will be1 cm = 5 km.
Classification of the map scale: There are various types of scales that are used in maps. They are
Statement scale: When the distance between two points on a map and the corresponding distance between these two points on the actual ground is expressed in a descriptive manner, i.e., in a statement form, it is called a statement scale. For
example,1 cm = 2 km. This means that a 1 cm distance on the map represents a 2 km distance on the ground.
2. Representative fraction scale: When the map distance and actual ground distance are expressed as a ratio, it is called a representative fraction. E.g., if on a map the scale is mentioned as 1:4000, it implies that 1 unit distance on the map is equivalent to 4000 units distance on the actual ground.
3. Graphical scale or drawn scale: When the distance on the map and the corresponding distance on the actual ground is shown with the help of a graphical representation, it is called a graphical scale. Graphical scales can be further divided into four types—
1. Linear scale: When the map distance and ground distance is represented by drawing a straight line with measurements on it, it is called a linear scale.
2. Comparative scale: when two different units are represented at the same time with different measurements indicated on either side points on the actual ground is expressed in a descriptive manner, i.e., in a statement scale.
3. Vernier scale: In this scale, a small scale slides along a main scale, indicating the actual measurement that lies between two marks on the main scale. This scale can measure very small areas.
4. Diagonal scale: When the primary divisions of a linear scale are converted into further subdivisions for accurate measurements, the scale used is called a diagonal scale.
Question 2 What are the uses and importance of scale in maps?
Answer:
Uses of scale in maps:
The different uses of scale in maps are as follows—
The actual size of any area on a map can easily be determined with the help of a scale.
1. Use of scale is mandatory for drawing an accurate map.
2. Any map can be reduced or enlarged accurately with the help of scale.
3. The distance between any two points can be measured on a map with the help of scale in order to determine the actual distance on the ground.
4. Land can be measured accurately using a vernier scale.
Importance of scale:
The importance of scale in maps is as follows—
1. A map cannot be drawn and is incomplete without a scale.
5. Scale is important for determining the length, width, etc., of any region.
1. Scale is valuable in determining the cost of building or contracting anything by a planner or a designer.
2. Vernier scale is important for taking minute measurements.

2. Representation of the Earth: The three-dimensional world can easily be represented on a two-dimensional surface (paper) with the help of a scale.
3. Other uses: Scales are vital in geographical research, surveys, defence purposes, etc.
Question 4 What are the advantages and disadvantages of a statement scale?
Answer:
A statement scale has various advantages and disadvantages.
Advantages: Some of its advantages are—
1. It is a simple scale, and can be used easily for interpreting maps.
2. As it is written in the form of a statement, there is no need for drawing.
3. Complex mathematical calculations are not required in this scale.
Disadvantages: Some of the disadvantages of a statement scale are—
1. Only the person who knows the language in which the scale is written will be able to comprehend it.
2. Changing the units of measurement is difficult in this system and is a time-consuming process.
3. If the map is enlarged or reduced, the scale has to be calculated again.
Question 5 mentions the advantages and disadvantages of a linear scale.
Answer:
A linear scale has its own set of advantages and disadvantages.
Advantages: Some of its advantages are
1. This scale is very easy to understand as the calculations are not complex.
2. In case of enlargement or reduction of the map, the linear scale gets reduced or enlarged proportionately. Thus, the map distance and the ground distance remain the same.
3. The area of a map can be easily determined with the help of this scale. A short distance on a map can also be measured accurately with the help of this scale.
Disadvantages: Some of its disadvantages are—
1. Calculations required for drawing this scale are very complex.
2. Designing the scale along with headings to make it presentable is a laborious and time-consuming process.
Question 6 How is the R.F. determined from a statement scale?
Answer:
Determination Of R.F. From A Statement Scale:-
When a scale of a map is expressed as a statement, it is known as a statement scale. This is the easiest way of writing a scale. A statement scale can be converted into R.F. scale in two ways.
1. Determination of R.F. by the formula: R.F= Map Distance/ Ground Distance
For example, if 16 inches on the map is equal to 1 mile on the ground, then
16 inches/ 63360 inches [1 mile= 63360 inches]
1/3960
Therefore, the R.F. of the map = 1: 3960
2. Determination of R.F. by the unitary method:
If a distance of 10 km on the ground is represented by l.cm on the map, the R.F. of that map will be,
1 cm on the map = 10 km on the ground or,
1 cm on map = 10 x 100000 cm = 1000000 cm
Therefore, the R.F. of the map = 1: 1000000.
Question 7 How can the statement scale be determined from the R.F.?
Answer:
Determination Of Statement Scale From R.F:-
The statement scale can be both R.F. in the given method— If the R.F. of a map is 1: 500000, the statement scale will be—
Distance of 1 cm on the map = 500000 cm on the ground or, 12.6 cm on the map = 31.5 x 100000 cm on the ground
Therefore, 1 cm on the map = 31-5 x 100000 = 250000 cm on the ground 12.6
Hence, the R.F. of the topographical map = 1: 250000.
or,.l cm on the map = =5 km on the , 100000 ground.
Therefore, the statement scale is 1 cm to 5 km.
Question 8 A railway line has been measured to be 12.6 cm in length on a topographical map. The actual length of that railway line is 31.5 km. What is the R.F. of the map?
Answer:
A distance of 12.6 cm on the topographical map = 31.5 km on the ground or, 12.6 cm on the map = 31.5 x 100000 cm on the ground folk
Question 9 What are the differences between a statement scale and a graphical scale?
Answer:
The differences between a statement scale and a graphical scale are as follows—
Differentiate between a fractional scale (representative fraction) and a graphical scale.
