NCERT Solutions for Class 11 Geography (Practical Work) Chapter 1 Introduction to Maps

Ans : (i) (d) Map Scale
(ii) (a) Cadastral map
(iii) (d) History of Maps 

Ans : (i) Map generalization, is the method whereby information is selected and represented on a map in a way that adapts to the scale of the display medium of the map, not necessarily preserving all intricate geographical or other cartographic details. For example, a general purpose map is drawn to show information such as relief, drainage, vegetation, settlements, means of transportation, etc.


(ii) Map design involves the planning of graphic characteristics of maps like appropriate symbols, their size and form, selection of colours and shades, etc. It requires thorough understanding of the principles that govern the effectiveness of graphic communication.


(iii) Small scale maps show large areas of land on a small space. They are called small scale because the representative fraction is relatively small. Small-scale maps are of two types:
(a) Wall Maps
(b) Atlas Maps


(iv) Large scale maps are drawn to show small areas at a relatively large-scale. Large-scale maps are of two types:
(a) Cadastral maps
(b) Topographical maps


(v) A selective, symbolised and generalised representation of the whole or part of the earth at a
reduced scale is called map, but simplified map drawn freehand which fails to preserve the true scale or orientation is called sketch. 

Ans : Types of Maps Based on Scale: On the basis of scale, maps may be classified into large-scale and small-scale. Large-scale maps are further divided into Cadastral maps and Topographic maps. Small-scale maps are further divided into the Wall Maps and Atlas Maps.
Types of Maps Based on Function: The maps may also be classified on the basis of their functions into physical maps and cultural maps. Physical maps show natural features such as relief, geology, soils, drainage, elements of weather, climate and vegetation, etc. Cultural maps show man-made features likes population distribution and growth, sex and age, social and religious composition, literacy, etc.
