Über dieses Buch

This book provides a comprehensive discussion on urban growth and sprawl, and how they can be analyzed using remote sensing imageries. It compiles views of numerous researchers that help in understanding the urban growth and sprawl; their patterns, process, causes, consequences, and countermeasures; how remote sensing data and geographic information system techniques can be used in mapping, monitoring, measuring, analyzing, and simulating the urban growth and sprawl and what are the merits and demerits of available methods and models.

This book will be of value for the scientists and researchers engaged in urban geographic research, especially using remote sensing imageries. This book will serve as a rigours literature review for them. Post graduate students of urban geography or urban/regional planning may refer this book as additional studies. This book may help the academicians for preparing lecture notes and delivering lectures. Industry professionals may also be benefited from the discussed methods and models along with numerous citations.

Chapter 1. Urban Growth and Sprawl

Abstract

Urban geography is the study of urban areas in terms of population concentration, infrastructure, economy and environmental impacts. The study of urban geography has evinced interest from a wide range of experts. The multidisciplinary gamut of the subject invokes the interest from ecologists, to urban planners and civil engineers, to sociologists, to administrators and policy makers, and the common people as well. This is because of the multitude of activities and processes that take place in the urban ecosystems everyday.

Chapter 2. Causes and Consequences of Urban Growth and Sprawl

Abstract

An overall idea about urban growth and sprawl has been provided in Chap. 1. This chapter is aimed to list the causes and consequences of urban growth and sprawl. The causes that force growth in urban area and the causes that are responsible for undesirable pattern or process of urban growth are also essentially important for the analysis of urban growth. The consequences or the impacts of urban growth, whether ill or good, are also necessary to be understood and evaluated towards achieving a sustainable urban growth.

Chapter 3. Towards Sustainable Development and Smart Growth

Abstract

This chapter provides basic concepts on sustainable development and smart growth. Detailed discussion on these issues is not within the scope of this book since it is mainly focused on the analysis of urban growth pattern and process. However, a basic understanding on sustainable development and smart growth will help to analyse the urban growth in terms of its acceptability of growth pattern/process or planning for the future. This chapter also documents several studies that are aimed to restrict the freedom of urban growth towards achieving the goals of smart and sustainable urban growth.

Chapter 4. Remote Sensing, GIS, and Urban Analysis

Abstract

Understanding urban patterns, dynamic processes, and their relationships is a primary objective in the urban research agenda with a wide consensus among scientists, resource managers, and planners; because future development and management of urban areas requires detailed information about ongoing processes and patterns. Central questions to be addressed are on how cities are spatially organised, where and when developments happen, why and how urban processes resulted in specific spatial pattern, and ultimately what may be the consequences of such pattern and/or process. Answers to these questions will definitely help us to prepare for the future in an equitable and sustainable manner; in specific, how the future planning should be done, whether to be more restrictive, how to overcome the ill effects of urban growth and sprawl, what policies should be appropriate in balancing the various competing goals of sustainability, and so on.

Chapter 5. Mapping and Monitoring Urban Growth

Abstract

Mapping of urban growth is different then the mapping of urban area. Urban area can be detected and mapped using a single temporal image, that is, image from a specific time. However, mapping of urban growth necessitates minimum of two temporal imageries; since it actually means the mapping of changes between two different times. This process is often called change detection—the process of identifying differences in the state of an object or phenomenon by observing it at different times (Singh 1989). Mapping of urban growth can lead to motoring of urban area and its growth through time.

Chapter 6. Measurement and Analysis of Urban Growth

Abstract

The process of mapping urban growth results in the creation of abstracted and highly-simplified change maps of the study area (as shown in Fig. 5.5). Examining these thematic change maps, even cursorily, one may see that expansion of built-up has different signatures: some areas are very compact while in others more open space between built-up areas. In some of the areas the boundary between the built-up and non-built-up is rather sharp, while in others these classes dissolve into each other. One can also see the infill of the open spaces between already built-up areas that results in their consolidation; or, one can understand whether the city is becoming more monocentric or polycentric over time. Surely, one can grasp these patterns intuitively, but they fall short of providing solid evidences for debating and deciding upon the future. To describe these different patterns intelligently, to understand how they change over time, to compare one subpart with others, or to explain the variations among these patterns statistically, we need to select quantitative measures that summarise one or another of their properties. Recently, urban change detection focus has been shifted from detection to quantification of change, measurement of pattern, and analysis of pattern and process of urban growth and sprawl.

Chapter 7. Modelling and Simulation of Urban Growth

Abstract

A model is a simplified representation of the physical system. They are the tools to simulate the behaviour of physical systems. They can predict the future evolution of the systems, they can be used as interpretative tools in order to study system dynamics, and they can give hints for data collection and design of experiments (Giudici 2002).

Chapter 8. Limitations of Urban Growth Analysis

Abstract

This chapter is aimed to discuss several limitations of urban growth analysis in brief. Remote sensing data are challenged by spatial, spectral, radiometric, and temporal resolutions as explained in Chap. 4. In addition to these general resolution constrains, there are several other issues associated with growth measurement and analysis.
