Über dieses Buch

This book documents research conducted on the analysis of urban growth and sprawl by using remote sensing data and GIS techniques. The research was conducted between 1980-2010 in the city of Kolkata, India. The aim of the research was to use metrics that were less demanding in terms of data and computation than normal metrics. However, it has been found that most of them were inferior in capturing insights of urban sprawl. For this book, some of these metrics have therefore been modified and new ones are proposed. The research focuses on problems associated with the analysis of urban growth by using remote sensing data from a technological perspective.

Chapter 1. Introduction

Abstract

This chapter introduces the study and research focused in this book. It aims to describe the background, significance, and objectives of the research; overview, questions that are to be answered in the research, and methodological overview. This chapter, as expected from any research-based book, acts as a prelude to all other chapters. The background section briefs the urban growth, sprawl, and the importance of remote sensing data and GIS techniques in urban growth analysis. The significance section documents the importance of current research. Other three sections (research objectives, research questions and methodological overview) will help to shape the readers’ outlook on the research.

Chapter 2. Review of Literature

Abstract

The literature on urban growth and sprawl is bigger than the scope of this chapter. Application of remote sensing and GIS in the study of urban growth/sprawl is also extensive in terms of their variations. A general research review cannot embrace the totality. However, in this chapter, efforts have been made to briefly document the important aspects that mainly focus on urban growth and sprawl, their patterns and processes, and measurement/analysis. It has been found that sprawl as a concept suffers from difficulties in definition. As a result, quantification of this phenomenon is rather complicated and sometimes confusing, especially if we use remote sensing data. There are dozens of metrics that are practiced by the urban planners and administrators in their cities, especially in developed countries. Merits and demerits of these measurements/analytical techniques have also been addressed briefly. It also documents similar studies in India, and proceeds toward the proposed research by documenting the scope of research.

Chapter 3. Methodology

Abstract

This chapter describes the data that have been used to perform the research, and the methodology adopted for the analysis of urban growth and sprawl. Methodology starts from image registration, then describes map encoding, image classification, accuracy assessment, determination of natural boundary, subdivision of natural boundary, calculation of built-up area, and finally analyses. The main problem faced in this research was lack of temporal ancillary data sets that were essential for many of the widely practiced metrics. Therefore, the intention was to use some metrics that are less demanding in terms of data and computation. However, it has been found that most of these metrics are inferior in capturing insights of urban growth and sprawl. In this chapter, therefore, most of these metrics have been modified, either to overcome their limitations or to fit the study area. This chapter is also aimed to justify the methods adopted in the current research. However, before proceeding through this chapter, one may refer to Appendix A for an overview of the study area.

Chapter 4. Results and Discussion

Abstract

This chapter displays the results obtained from the digital classification of remote sensing data as well as the results obtained from different analyses. The study concludes that, for the analysis of urban growth and sprawl, the natural boundary of the city is preferred compared to the administrative boundary. However, whether the administrative or the natural boundaries are in consideration, it has been found that the city of Kolkata was always sprawling. The results have also shown that the rate of urban growth in Kolkata is generally higher than the growth rate of the population as well as the growth rate of households. Among the metrics and models used to quantify the sprawl, Shannon’s entropy has been established as the most preferred. This chapter also focuses the discussions on the observed results. It also makes arguments on the methodology in terms of their merits and limitations, and constructs logical statements.

Chapter 5. Conclusions

Abstract

This chapter aims to draw the conclusions and to highlight the future scope of research and study. It draws conclusions not only on the urban growth and sprawl for the city of Kolkata, but also on the methods and metrics used or modified or proposed in the current research. Future research directions have also been made based on the limitations of the current research (documented in Chap. 4). This research may aid into help local authorities in general to establish and evaluate development goals in terms of establishing social and other infrastructure equipments considering the threats of urban sprawl in achieving sustainable development. Apart from the derived conclusions, the research also shows the potentials of remote sensing and GIS for the analysis of urban growth and sprawl in spatio-temporal scales.
