Thesis Abstract

Abstract
The integration of Unmanned Aerial Vehicle (UAV) technology in land surveying and mapping applications has revolutionized the field of geospatial data collection and analysis. This thesis explores the opportunities and challenges associated with the utilization of UAVs for surveying and mapping purposes. The primary objective of this research is to investigate how UAV technology can enhance the efficiency, accuracy, and cost-effectiveness of traditional land surveying and mapping methods. The introduction provides an overview of the increasing demand for accurate and up-to-date geospatial data in various sectors such as urban planning, agriculture, environmental monitoring, and disaster management. The background of the study highlights the evolution of UAV technology and its applications in land surveying and mapping. The problem statement identifies the limitations of conventional surveying methods and the potential benefits of incorporating UAVs into the workflow. The objectives of the study are to assess the accuracy and reliability of UAV-based surveying and mapping techniques, analyze the cost-effectiveness of UAV technology compared to traditional methods, and investigate the operational limitations and challenges faced in implementing UAVs for surveying and mapping applications. The scope of the study covers the use of UAVs for topographic mapping, cadastral surveying, infrastructure monitoring, and environmental assessment. The significance of the study lies in its potential to contribute to the advancement of geospatial data collection practices by leveraging UAV technology. The research methodology involves a comprehensive literature review of existing studies on UAV applications in surveying and mapping, field experiments to evaluate the performance of UAV-based techniques, and data analysis to compare the results with conventional surveying methods. The literature review encompasses ten key areas, including the evolution of UAV technology, sensor payloads for aerial surveys, data processing and analysis techniques, accuracy assessment methods, regulatory framework for UAV operations, and case studies of successful UAV applications in land surveying and mapping. The findings from the literature review provide valuable insights into the current state of UAV technology in the geospatial industry. The research methodology section outlines the data collection process, experimental design, UAV platform selection, sensor calibration procedures, flight planning and execution, image processing techniques, ground control point establishment, and accuracy assessment methods. The study also addresses the ethical considerations and safety protocols associated with UAV operations in surveying and mapping projects. The discussion of findings presents a detailed analysis of the experimental results, including the accuracy assessment of UAV-derived orthophotos and digital elevation models compared to ground truth data. The cost-effectiveness analysis evaluates the operational expenses of UAV surveys in terms of equipment, personnel, and data processing software. The challenges and limitations of UAV technology, such as flight restrictions, weather conditions, and data quality issues, are also discussed. In conclusion, the integration of UAV technology in land surveying and mapping applications offers significant advantages in terms of efficiency, accuracy, and cost-effectiveness. However, several challenges need to be addressed to fully realize the potential of UAVs in the geospatial industry. This thesis contributes to the body of knowledge on UAV applications in surveying and mapping and provides recommendations for future research and implementation strategies in this rapidly evolving field.
