TOPIC:-

Integrating GIS and Remote Sensing

in modelling urban sprawl: A case

study of Vijayawada

Introduction:-

Now a days, Remote sensing and Geographic Information System (GIS) are used at

all levels of decision making, policy interventions and many urban applications.

The important background study for implementing any of these action will be to

analyse the urban area and to predict the urban sprawl. With the available

technology this can be made possible by integrating remote sensing and GIS

techniques. Mathematically speaking, a modelling of urban sprawl must be done

using various mathematical techniques already available on hand from the

literature available.

Need for the study:-

Case study area :-

Vijayawada is a city on the banks of the Krishna River, in

the Indian state of Andhra Pradesh. It is a municipal corporation and the

headquarters of Vijayawada (urban) mandal in Krishna district of the state. The

city is one of the suburbs of the state capitalAmaravati, under the Andhra Pradesh

Capital Region, and the headquarters of Andhrapradesh capital Region

Development Authority ( APCRDA) .Vijayawada city is governed by Municipal

Corporation which comes under Vijayawada Metropolitan Region. The

Vijayawada city is located in Andhra Pradesh state of India. As per provisional

reports of Census India, population of Vijayawada in 2011 is 1,034,358; of which

male and female are 518,590 and 515,768 respectively. Although Vijayawada city

has population of 1,034,358; its urban / metropolitan population is 1,476,931 of

which 743,267 are males and 733,664 are females. The present city area is 61.88

sq.kms .

• Metrics for modelling urban sprawl are not quantified for most of the urban centres in India.

• Impact of a new city construction over another city has not been taken as a parameter using GIS an RS in any of the studies so far done.

• As capital city of Amaravathi is coming up , Vijayawada will be having a lot of urban growth.

• Urban growth conventionally in master plans is predicted using simple growth rate method & housing demand , but if we can implement statistical analysis and techniques for predicting it most of the urban issues will be solved.

Flow of the study :-

Efforts will be made to predict potential urban development in accordance with

the existing and/or planned infrastructure with the use of “Shannons entropy

method “ employed in GIS. The case study area is the city of Vijayawada in state

of Andhrapradesh. In this study,The Landsat imageries will be employed in

modelling urban sprawl in this area for the period.The time period will be chosen

based on the data available from the National Remote sensing center (NRSC),

Hyderabad. The parameters for urban sprawl will be identified from the literature

study and as well as from the case area. For accuracy assessment after the Image

classification is made “Kappa statistics” will be employed.

Intentions & Conclusion of the study:-

Urban growth is responsible of many consequent problems such as: increasing the

time travel, increasing the car dependency transportation, increasing the costs of

infrastructures, living and transportation and pollutions. Thus, a policy for better

management of the city and to decrease the urban sprawl problems is the vertical

development of the city and determine a set of certain and accurate policies

about the growth of city boundaries.
