Thesis Abstract

Abstract
Urban heat islands (UHIs) are a pressing environmental issue in major cities worldwide, impacting the health and well-being of urban residents, as well as energy consumption and overall urban climate. Remote sensing techniques offer a valuable tool for the analysis of UHIs due to their ability to capture spatial and temporal variations in surface temperatures across urban areas. This thesis presents a comprehensive analysis of UHIs in major cities using remote sensing techniques, with a focus on understanding the causes, extent, and implications of these phenomena. Chapter 1 provides an introduction to the research topic, outlining the background of the study, stating the problem statement, defining the objectives, discussing the limitations and scope of the study, highlighting the significance, and presenting the structure of the thesis. Chapter 2 comprises a detailed literature review that explores existing research on UHIs, remote sensing techniques, and previous studies related to the analysis of urban heat islands in major cities. This chapter aims to provide a theoretical framework for the research and identify gaps in the current literature that this study seeks to address. Chapter 3 outlines the research methodology employed in this study, including the selection of study areas, data collection methods, remote sensing techniques used for temperature analysis, and statistical approaches for data interpretation. The chapter also discusses the challenges encountered during data collection and analysis processes. Chapter 4 presents the findings of the study, including spatial patterns of UHIs in major cities, temporal variations in surface temperatures, factors contributing to UHI intensity, and the relationship between UHIs and urban land use patterns. The chapter also discusses the implications of these findings for urban planning and climate mitigation strategies. Chapter 5 offers a comprehensive conclusion and summary of the thesis, highlighting the key findings, discussing the implications for future research and policy development, and providing recommendations for addressing UHIs in major cities using remote sensing techniques. The chapter also reflects on the significance of the study in the context of urban sustainability and climate resilience. Overall, this thesis contributes to the growing body of knowledge on UHIs in major cities and demonstrates the value of remote sensing techniques for analyzing and monitoring urban heat islands. By gaining a better understanding of UHIs and their impacts, urban planners and policymakers can develop more effective strategies for mitigating heat-related risks and improving the overall quality of life in urban areas.

Thesis Overview

The project titled "Analysis of Urban Heat Islands in Major Cities Using Remote Sensing Techniques" aims to investigate the phenomenon of urban heat islands in major cities and explore how remote sensing techniques can be utilized to study and analyze these heat islands. Urban heat islands refer to the localized areas within urban environments that experience significantly higher temperatures compared to the surrounding rural areas. This project seeks to understand the drivers and impacts of urban heat islands, particularly in major cities where the phenomenon is more pronounced due to high population density, extensive infrastructure, and limited green spaces. By employing remote sensing techniques, such as satellite imagery and thermal infrared sensors, the project will gather data on land surface temperatures and land cover characteristics in selected major cities. These data will be analyzed to identify urban heat island hotspots, assess the spatial distribution of heat islands within the cities, and examine the relationship between land cover types and temperature variations. The study will also investigate the temporal dynamics of urban heat islands to understand how these phenomena evolve over different timescales, from daily fluctuations to seasonal variations. Through this research, valuable insights can be gained into the factors contributing to the formation and intensification of urban heat islands in major cities. The findings of the study will not only enhance our understanding of urban microclimate dynamics but also provide important information for urban planners, policymakers, and environmental scientists to develop strategies for mitigating the impacts of heat islands. By identifying areas within cities that are most vulnerable to heat stress, appropriate urban planning interventions and mitigation measures can be implemented to enhance the resilience of urban environments and improve the quality of life for residents. Overall, this project represents a significant contribution to the field of urban climatology and remote sensing by addressing the pressing issue of urban heat islands in major cities. By combining advanced remote sensing techniques with spatial analysis and geospatial modeling, the research aims to generate valuable knowledge that can inform sustainable urban development practices and climate change adaptation strategies. Through its interdisciplinary approach, the project seeks to bridge the gap between scientific research and practical applications, ultimately fostering a more resilient and sustainable urban future.
