Thesis Abstract

Abstract
The integration of Unmanned Aerial Vehicles (UAVs) in high-precision topographic mapping for urban planning has emerged as a cutting-edge technology with the potential to revolutionize the field of surveying and geo-informatics. This thesis explores the utilization of UAVs to acquire accurate and detailed topographic data to support urban planning activities. The primary objective of this research is to investigate the capabilities and limitations of UAV-based topographic mapping in urban environments, focusing on its accuracy, efficiency, and cost-effectiveness compared to traditional surveying methods. The research methodology employed a combination of literature review, case studies, and practical fieldwork to assess the feasibility and performance of UAVs for topographic mapping applications. Chapter two provides a comprehensive review of existing literature on UAV technology, topographic mapping techniques, and urban planning practices to establish a theoretical framework for the study. The literature review also examines the advantages and challenges associated with UAV-based topographic mapping in urban contexts. Chapter three outlines the research methodology, including the selection of study areas, data acquisition procedures, data processing techniques, and accuracy assessment methods. The methodology section details the technical specifications of the UAV platform used, the flight planning process, and the photogrammetric processing workflow to generate high-resolution topographic maps. Moreover, the chapter discusses the validation of UAV-derived data through ground control points and accuracy assessment analyses. Chapter four presents a detailed discussion of the findings from the fieldwork and data analysis. The results highlight the accuracy and quality of UAV-derived topographic maps in urban areas, showcasing the potential of UAV technology to provide high-resolution spatial data for urban planning applications. The discussion also addresses the challenges encountered during data collection, processing, and interpretation, offering insights into improving the efficiency and reliability of UAV-based topographic mapping. In conclusion, this thesis emphasizes the significance of UAV technology in advancing high-precision topographic mapping for urban planning initiatives. The study demonstrates the practicality and effectiveness of using UAVs to acquire detailed topographic data in urban environments, leading to enhanced decision-making processes and sustainable urban development strategies. The research findings contribute to the growing body of knowledge on UAV applications in surveying and geo-informatics, offering valuable insights for researchers, practitioners, and policymakers in the field.
