In a significant advancement for topographic surveying, a recent study has demonstrated the powerful combination of Unmanned Aerial Vehicle (UAV) technology and Light Detection and Ranging (LiDAR) in mapping complex mountainous terrains, specifically in the context of the Win 3 Wind Power Plant Project in Huong Hoa District, Quang Tri Province, Vietnam. The research, led by Trong Tran Dinh from the Department of Geodesy and Geomatics Engineering at Hanoi University of Civil Engineering, reveals how this innovative approach can revolutionize geographic data collection, particularly in challenging environments.
The study utilized the DJI Matrice 300 RTK UAV equipped with advanced LiDAR capabilities, achieving an impressive point density of 229 points per square meter. This high level of detail, combined with ultra-high-resolution imagery of 4.22 cm per pixel, allowed researchers to produce a comprehensive topographic map at a scale of 1:1,000, complete with 3D point clouds and a Digital Elevation Model (DEM). “The integration of aerial LiDAR and photographic data results in a rich and detailed information repository regarding the surveyed terrain,” Tran Dinh noted, emphasizing the robustness of UAV LiDAR technology in geographic data collection.
The implications of this research extend far beyond academic interest; they present a commercial boon for the energy sector, particularly in the development of renewable energy projects like wind farms. Accurate and efficient mapping is crucial for site selection, environmental assessments, and project planning. By leveraging UAV LiDAR technology, energy companies can significantly reduce the time and costs associated with traditional surveying methods, enabling faster project development and implementation. This efficiency not only enhances operational capabilities but also contributes to more sustainable practices by minimizing environmental disruption during the surveying process.
The study’s findings underscore the potential for UAV LiDAR technology to set new standards in the field of geographic data collection. With the accuracy of the generated topographic maps exceeding technical requirements and quality standards, the research paves the way for more sophisticated applications in energy infrastructure planning and development. As the energy sector increasingly turns toward renewable sources, the ability to conduct precise surveys in difficult terrains will be paramount.
This research was published in ‘Reports on Geodesy and Geoinformatics,’ a journal dedicated to advancements in geodesy and geoinformatics. As the energy landscape continues to evolve, the integration of UAV and LiDAR technology may well become a cornerstone for future developments, shaping how projects are planned and executed in the years to come.
