Introduction to Maps

Chapter: 24

GEOGRAPY [ PART – III ]

VERY SHORT ANSWER TYPE QUESTIONS

Q.1. What is a map?

Ans. A map is a diagrammatic representation of the whole or a part of the earth and its surface features at a given scale.

Q.2. What is cadastral map?

Ans. The term cadastral is derived from French word ‘cadaster’ meaning register of territorial property. The cadastral maps are drawn to register the ownership of landed property by demarcating the boundaries of fields.

Q.3. What are cardinal points?

Ans. The major directions north, south, east and west are called cardinal points.

Q.4. What are the types of maps according to scale?

Ans. (i) Topographical maps.

(ii) Cadastral maps.

(iii) Wall maps.

(iv) Atlas maps.

Q.5. What are essential features of maps?

Ans. Title, scale, key, map projection, directions and conventional signs are essential features of the map.

Q.6. What is the basis of the classification of the map?

Ans. (i) Scale.

(ii) Purpose.

SHORT ANSWER TYPE QUESTIONS

Q.1. What is map generalisation?

Ans. Generalisation means purpose of the map. Every map is drawn with a definite objective for example map is drawn to show relief, drainage, vegetation, etc.

Q.2. Why is map design important?

Ans. Map design is important. It involves the planning of graphic characteristics of maps including the selection of appropriate symbols, their size and form, colour, legend, etc.

Q.3. What is a scale? What purpose does it serve on a map?

Ans. Scale is the relationship between the distance on a map and the real distances on the earth’s surface. A scale enables us to prepare accurate maps and helps in measuring distance.

It is an important element of a map because it gives relative feature of the ground reality. It shows the relationship between the distance on the earth and on the piece of paper.

Q.4. What are small scale maps? Give two examples of small scale maps.

Ans. The small scale maps represent large areas on small sheet of paper. These have fewer details. Examples of small scale maps are Atlas and Wall maps.

Q.5. What is difference between globe and map?

Ans. Globe is a man-made model which represent earth on a curved surface. Globe is more accurate but it is difficult to use it. On the other hand, map is less accurate but it is more convenient to use map as compared to globe.

Q.6. What is globe?

Ans. A globe is a man-made model of the earth. It represents the shape of earth accurately. It shows the shape of oceans and continents correctly. It shows the correct position of the places on the earth in rotation to one another.

Q.7. What are the characteristics of maps?

Ans. Characteristics of maps:

(i) A map is representation of an area on a flat sheet of paper.

(ii) Maps are drawn on a world definite scale. Without scale, a map is simply a rough sketch.

(iii) Conventional signs are used to show the various features of the earth surface.

(iv) Maps have two dimensions-length and breadth.

Q.8. What do you understand by the terms chart and plan?

Ans. The word ‘chart’ has been derived from the word ‘carte’ a French word. It means a map. A chart is simply a diagram showing the different types of statistics. Charts are generally used to show the ocean routes.

The word plan is used for property maps of cadastral maps. These have a scale larger than 6″-1 mile. Then shows the details of the property of land or a building.

Q.9. What are the different types of small scale maps? 

Ans. 1. Wall maps.

2. Atlas maps.

Q.10. List out two major types of large scale maps. 

Ans. 1. Cadastral maps.

2. Topographical maps.

Q.11. How is map different from a sketch?

Ans. The scale is essential to draw a map while sketch can be drawn without a scale.

LONG ANSWER TYPE QUESTIONS

Q.1. What are the advantages of map over a globe?

Ans. The earth is a sphere. A globe is the true representation of the earth. The globe is a small model of the earth. But sometime we have to face many problems in using a globe. So it has become necessary to use maps. Generally maps are preferred to globes for their use for educational purpose.

(i) The whole earth cannot be studied from a globe.

(ii) Globe do not show a large number of details. These can be shown on map.

(iii) Distance cannot be measured on a globe because it is a curved surface.

(iv) Maps can be easily handled.

(v) A comparative study of two areas is not possible on a globe.

(vi) Maps can be easily incorporated in books or bounded in Atlas.

Q.2. What are the large scale maps? What are types of these maps?

Ans. These maps show more details: They are large in size. These have a scale of 6″ = 1 mile. These show the details of buildings and property.

These, maps are of following four types on the basis of scale:

(i) Cadastral maps: These maps show full details of buildings and properties and are known as ‘plans’.

(ii) Topographical maps: Survey of India prepares these maps on a scale of 1:50,000 or inch: 1 mile. These are large scale maps showing the natural and man-made features of an area.

(iii) Wall maps: These are small scale maps used educational purposes.

(iv) Atlas maps: These are small scale maps, bound together in the form of an Atlas. These are best suited for eduational purposes.

Q.3. Write short notes on:

(i) Wall maps.

Ans. Wall maps: These maps are generally drawn boldly so that they can be seen from a distances. They are used in classrooms and later to a large audience. These maps broadly show very large areas like world as a whole, continents and countries etc. The scale is smaller than that of topographical maps but larger than atlas maps.

(ii) Linear scale.

Ans. Linear scale: This scale is expressed as a straight line. The base is calibrated to express visual equivalents of representative fraction or verbal scale. The basis are divided into a number of equal parts and are marked to show that these divisions represent on actual ground. The scale has the advantage that it remains true even after reduction or enlargement of the map. Distances on the map are smaller than the corresponding distance on actual ground.

(iii) Base direction line.

Ans. Base direction line: Direction has been defined as an imaginary straight line on the map or the ground showing the angular position of various maps with respect to a common base direction. The time pointing to the north is regarded as the zero direction or base direction line.

Q.4. Write an explanatory account of types of map.

Ans. Maps are different types. Maps are broadly classified on the basis of

1. scale. and

2. purpose.

According to scale:

1. Large scale maps: These maps represent small area of the earth on a large size of paper sheet with greater details. Examples: Cadastral maps, topographical maps.

2. Small scale maps: These maps represent large areas on a small sheet of paper. They have fewer details. Examples are Atlas and Wall maps.

According to purpose they are:

(i) Physical or natural maps: Such as relief maps include features like plains, plateaus and mountains.

(ii) Cultural maps: These maps show the man-made features or human aspects such as political and historical maps.
