been developed for the determination of the built-up area as easy, rapid and valuable
tools. These indices are independent and do not need sophisticated software. Here,
the reflectance values of each and every terrestrial objects are considered, and
according to the prime objective or the hypothesis of the research, multiple bands
have been considered for rationing and indexing. Likewise, the images they create
can be used by classification techniques to calculate the built-up area (Xu 2007; Lee
et al. 2010).
8.2 Objectives
The main objective of the present paper is to find out the recent trend of growths of
the built-up area in some selected major urban areas of West Bengal, India.
8.3 The Study Areas
As per the 2011 census report of India, West Bengal has an urban population of over
29 million which accounts to 31.87% of the total population of the state. The total
number of city (more than one lakh people) and urban agglomerations (UA) is 29 as
per the 2011 census report of India. Kolkata, Asansol, Siliguri and Durgapur are the
four largest cities or UA among them in terms of their population (except Howrah).
The total share of these cities is over 57% of population to the total urban population
of West Bengal (Census of India 2011). The disparity of urban growth is not only
spatial but temporal too. A brief description of the study area is given below.
8.3.1 Kolkata Municipal Corporation (KMC)
Kolkata was the erstwhile capital of India and has a historical growth records and
the present capital of the state as well as the densest city in West Bengal. Here, constructional activity started in the era of Britisher, i.e. from the seventeenth century.
Now Kolkata is the state capital of West Bengal and the business capital of eastern
India. River Hoogly is flowing beside the city and it is still navigable for foreign
trade. Out of the total urban population in West Bengal, more than 48% of urban
population are concentrated here. Although the growth rate of the city is almost
slow and stagnant, the built-up (BU) area almost completed mostly in the central
part of the city, and major change of BU can be seen in the eastern and southern and
western fringe of the city.
