Analysis of Urban Expansion Using Remote Sensing and GIS Techniques

Thesis Abstract

Abstract
Urban expansion is a phenomenon that has significant implications for the environment, society, and economy. This thesis presents a comprehensive analysis of urban expansion using remote sensing and Geographic Information Systems (GIS) techniques. The study aims to investigate the patterns and drivers of urban expansion in a selected area, assess the impacts of urban growth on the environment, and propose sustainable planning strategies to manage urban expansion effectively. The research methodology involved the collection of satellite imagery data and spatial datasets to analyze land cover changes over a specific period. Various GIS tools and techniques were utilized to extract information on urban expansion trends, spatial patterns, and associated factors. The study area selected for this research is a rapidly urbanizing region experiencing significant population growth and land use changes. The literature review provides a critical analysis of existing studies on urban expansion, remote sensing applications, GIS technologies, and urban planning strategies. It explores the relationship between urban growth and environmental degradation, socio-economic impacts, and sustainable development practices. The review also highlights the importance of using geospatial tools for monitoring and managing urban expansion. The findings of the study reveal significant patterns of urban expansion, including the conversion of agricultural land into built-up areas, the encroachment of natural habitats, and the fragmentation of landscapes. The analysis identifies key drivers of urban growth, such as population growth, infrastructure development, and economic activities. The study also assesses the environmental impacts of urban expansion, such as loss of biodiversity, increased pollution, and changes in hydrological patterns. Based on the research findings, the thesis proposes a set of recommendations for sustainable urban planning and management. These recommendations include the adoption of smart growth principles, the implementation of green infrastructure strategies, and the establishment of land use policies to guide future development. The study emphasizes the importance of integrating remote sensing and GIS technologies into urban planning processes to support informed decision-making and promote sustainable urban development. In conclusion, the analysis of urban expansion using remote sensing and GIS techniques provides valuable insights into the dynamics of urban growth and its impacts on the environment. By understanding the patterns and drivers of urban expansion, policymakers and planners can develop effective strategies to address the challenges of rapid urbanization and promote sustainable development practices. This research contributes to the growing body of knowledge on urban expansion and underscores the importance of leveraging geospatial technologies for urban planning and environmental management.
