Answer in Brief
1. What is scale?
Answer: Scale is a ratio between distances on the map and distance on actual ground.
2. How many types of maps are drawn based on different scales? Mention the types.
Answer: Based on scale, maps can be categorized into three types:
(i) Small Scale map
(ii) Medium Scale map
(iii) Large Scale map
3. What is map?
Answer: Map is a drawing or picture of a definite region on the surface of the earth. The map may be defined as the representation of the earth’s pattern as a whole or a part of it on a plane surface drawn to a scale and projection so that each and every point on it corresponds to the actual terrestrial position. Professor Halford Mackinder defined maps as “Maps are the tools of the Geography”. Map is a special language which is expressed by line, colour, conventional sign etc.
4. Write two important aspects of map.
Answer: Two important aspects that a map depends on are:
(i) scale
(ii) Projection
5. How many types of scales are used in map making and mention them?
Answer: Scale may be of three main types used in map making:
- Statement scale
- Representative Fraction scale
- Graphical scale.
6. What is the importance of scale?
Answer: Scale is important for several reasons:
(i) It is used to draw a map.
(ii) It allows drawing a large area or the whole world on a small piece of paper.
(iii) Maps can be enlarged or reduced according to scale.
(iv) Scale is useful for surveying.
(v) It helps to measure the total area of a map.
(vi) By using scale, we can determine the distance between two places on the map.
(vii) It helps to get a diagram of a large area.
(viii) It allows determining the total length of a river drawn on the map.
(ix) From R. F (Representative Fraction) we can draw a map.
7. Define Representative fraction scale.
Answer: Representative Fraction Scale, or R. F., is defined as the ratio of Map distance to Ground distance (R. F. = Map distance / Ground distance). An example is RF 1:45,000,000.
8. Define Statement scale.
Answer: A Statement scale expresses the scale in words. Examples include (i) One inch to a mile, (ii) Six inches to a mile, (iii) One centimetre to four kilometre, (iv) One centimetre to fifty Kilometre.
9. Define Linear scale.
Answer: When we draw a scale by using one or more straight lines to show the ratio between map distance and ground distance it is termed as linear scale. This scale shows two divisions: (i) Primary division (ii) Secondary division. Normally we show secondary division in the left hand side and primary division in the right hand side of a scale.
Essay Type Questions
1. Write definition of map, uses of map and importance.
Answer: A Map helps to acquire knowledge about geography.
The definition of a map is as follows: Map is a drawing or picture of a definite region on the surface of the earth. The word ‘Map’ is derived from latin word “Mappa”. The map may be defined as the representation of the earth’s pattern as a whole or a part of it on a plane surface drawn to a scale and projection so that each and every point on it corresponds to the actual terrestrial position. Professor Halford Mackinder defined as “Maps are the tools of the Geography”. Map is a special language which is expressed by line, colour, conventional sign etc.
The importance and uses of Maps are:
- Maps are the tools of Geographers. No other science is so much dependent upon maps as geography though all use maps and diagrams to illustrate their facts and data.
- Not unlike books maps are also records of various facts regarding the earth.
- With the help of topographical maps regional geography of a country may be systematically described.
- Maps are true guides not only to geographers but to other individuals like travellers, tourists etc.
- During operations maps render much help by indicating various routes and possible enemy position. this is why the public use of the topographical maps is restricted during war.
- Businessmen, industrialists and managers of factories and workshops also need maps and charts.
- Maps are useful for planning and conservation of natural resources of a country.
- From a mouza map students get proper knowledge about boundaries of land holdings, roads, rivers, ponds, settlements, temples, mosque, burial grounds by various conventional signs used in maps.
- For administrative work maps are required in different government departments.
- From maps adequate informations are generated regarding agricultural crops, minerals, industries, population, town and city, rural habitant etc.
2. Illustrate in brief with diagram about elements of map.
Answer: For any map making and to have actual information from map, it is required to implicate six essential elements related to it. Those six elements are : (A) Title (B) Direction (C) Scale (D) Latitude and Longitude (E) Legend (F) Boundary.
These elements are briefly described as:
A. Title of Map : Every map is specified by a title for explicit idea about the type of map made for i.e., Political map of world, Map of Agricultural product of India.
B. Direction : In most cases during map making one arrow [↑] sign is used to indicate North direction. This is called North Line.
C. Scale: Map making is done in accordance with a particular scale of measurement. It scale of measurement is not used during map making it turns out insignificant and then it is defined as sketch map.
D. Latitude and Longitude : There must be exact specification of latitude and longitude in any map.
E. Conventional Sign : The conventional signs and colours used in maps should be mentioned properly on either left or right hand side of the map.
F. Boundary : The name of the states, districts or neighbouring countries should be mentioned on the boundaries of the map.
[This answer needs diagram present on Page number 2 of the chapter, Fig. 9.1]
3. Classify maps according to scale used and describe large scale maps with diagram.
Answer: Maps can be classified according to the scale used. Scale wise, maps can be Small Scale maps, Medium Scale maps, or large Scale maps.
Examples of Small Scale maps include (i) Wall map (ii) Atlas (iii) International map (iv) Globe.
Examples of Medium Scale maps include (i) Blue diagram (ii) Cadastral map (iii) Wall map (iv) Topographical map (v) Soil map.
Large Scale maps show details either in miles/inches or Kilometers/Centimeters. Here unit is mile or km. An example of a large scale map is a Village Map.
[This answer needs diagram present on Page number 5 of the chapter , Fig. 9.3 for large scale map and the classification diagram on Page 3]
4. Describe small scale map.
Answer: A Small Scale map shows either miles in inch or kilometers in centimeters. Here unit is inch and cm. For an example 1´´ = 10 mile ; 1cm = 5km.
Examples of Small Scale maps include (i) Wall map (ii) Atlas (iii) International map (iv) Globe. A map of Bangladesh with a fractional scale of 1″ to 100 mile is an example of a small scales map.
5. Describe the linear scale, its importance and making procedure.
Answer: A Linear Scale is defined as follows: When we draw a scale by using one or more straight lines to show the ratio between map distance and ground distance it is termed as linear scale. This scale shows two divisions : (i) Primary division (ii) Secondary division. Normally we show secondary division in the left hand side and primay division in the right hand side of a scale.
The importance and uses of scale, including linear scale, for the preparation of a map are:
(a) To measure distances between two points on the map.
(b) to measure out a certain length from the scale.
(c) To show the actual shape of a country or a continent.
(d) To enlarge or reduce a map according to scale.
Further advantages include:
(i) By using scale we can determine the distance between two places on the map.
(ii) To get a diagram of a large area.
(iii) to get the total length of a river drawn on the map.
(iv) From R. F we can draw a map.
Scale is also used to draw a map, to draw a large area or whole world on a small piece of paper, and is useful for surveying and to measure total area of map.
The making procedure of a linear scale involves drawing it using one or more straight lines. It is constructed to show two divisions: a Primary division and a Secondary division. Typically, the secondary division is shown on the left hand side and the primary division is shown on the right hand side of the scale.
6. Write about statement scale.
Answer: A statement scale is one of the three main types of map scales. It expresses the scale in words. For example, a statement scale can be written as: 1 cm = 10 km.
Other examples include:
(i) One inch to a mile
(ii) Six inches to a mile
(iii) One centimetre to four kilometre
(iv) One centimetre to fifty Kilometre.
