The project titled "Integration of Unmanned Aerial Vehicles (UAVs) and LiDAR Technology for Detailed 3D Mapping of Urban Areas" aims to explore and demonstrate the synergistic use of UAVs and LiDAR technology to enhance the precision and efficiency of 3D mapping in urban environments. Urban areas are characterized by complex layouts, diverse structures, and dynamic features, making traditional surveying and mapping methods challenging and time-consuming. The integration of UAVs, equipped with LiDAR sensors, offers a novel approach to address these challenges by providing high-resolution, georeferenced data for detailed 3D mapping. The research will begin with a comprehensive review of existing literature on UAVs, LiDAR technology, and their applications in surveying and mapping. This review will highlight the advantages and limitations of UAV-LiDAR systems and identify gaps in current research that the project aims to address. The methodology will involve conducting field surveys and data collection using UAVs equipped with LiDAR sensors in selected urban areas. The collected data will be processed and analyzed using advanced software tools to generate accurate 3D maps and models. The project will also compare the results obtained from UAV-LiDAR surveys with traditional surveying methods to evaluate the efficiency and accuracy of the integrated approach. The discussion of findings will focus on the effectiveness of UAV-LiDAR integration in capturing detailed 3D information in urban areas, including buildings, infrastructure, and terrain features. The research will also explore the potential applications of the generated 3D maps in urban planning, disaster management, infrastructure development, and environmental monitoring. In conclusion, this project seeks to demonstrate the feasibility and benefits of integrating UAVs and LiDAR technology for detailed 3D mapping of urban areas. The findings and recommendations from this research will contribute to the advancement of surveying and geoinformatics practices, offering new insights and approaches for efficient and accurate mapping of complex urban environments.
