| Abstract | Abstract : This thesis investigates the performance and capabilities of the HCD LiDAR scanner for topographic surveying applications. The study employed a methodology for data collection, processing, and analysis using specialized software tools, including Civil 3D, Cloud Compare. The results of the volumetric survey revealed that the HCD LIDAR scanner marked 0.631% of error when compared to the Leica Scan Station P20 scanner and 0.223% when compared to Leica GS18 T GNSS RTK data, indicating a high level of precision and accuracy in the measurements. Additionally, the HCD LiDAR scanner demonstrated its ability to perform a wide range of topographic applications, including creating contour maps, profile views, and DEM models with custom grid size. The study also employed C2C and M3C2 algorithms to evaluate the accuracy of the data collected, with the results showing a high level of accuracy which marked a standard deviation of 0.413 m and 0.417 m in the x and y axis coordinates respectively; and a relatively fair accuracy in the z axes coordinates with a standard deviation of 0.076 m in the z axes coordinates, as well as an overall absolute distance that indicates 90% of the data is below 0.148m of error. This study also assessed the distance relative accuracy of the HCD LIDAR scans, considering both single scans and combined scans. The results showed that the accuracy of distances in single scans was 0.078 m, while the accuracy of distance from the combined scans was 0.083 m. These findings indicate the reliable connectivity of combined scans and encourages future research studies in covering larger area by making use of HCD LiDAR technology. In conclusion, the findings of this thesis have important implications for various applications, including land surveying, infrastructure development, and environmental monitoring. Furthermore, the study provides recommendations for future research and practical applications, including further research on the performance of the HCD LiDAR scanner and other emerging technologies, the development of software tools and applications, and ongoing training and education for practitioners and researchers. Overall, this thesis contributes to a better understanding of the capabilities and limitations of the HCD LIDAR scanner for topographic surveys, providing valuable information for various fields and applications. | |
