Application of UAVs with GNSS, LiDAR, and Photogrammetry Technologies in Terrain Mapping

Abstract

This paper offers a comprehensive summary of recent publications that explore the use of UAV technology for terrain mapping. The results obtained from these studies indicate that integrating UAVs with photogrammetry, LiDAR, and GNSS technologies is highly effective for producing detailed and accurate topographical maps. These technologies enable the precise representation of terrain features, making them invaluable for various mapping applications. The study not only highlights the practical applications of UAV technology in topographic mapping but also serves as a technical reference for advancing knowledge and understanding of these applications. By examining the methodologies and outcomes of numerous research efforts, this paper provides insights into the capabilities and benefits of using UAVs for terrain mapping. It underscores the importance of UAVs in enhancing the accuracy and efficiency of topographic surveys, particularly in challenging environments.
