LiDAR Technology for Efficient and Accurate Large-Scale Mapping and Cadastral Surveying

LiDAR technology has emerged as a superior tool for largescale mapping, particularly in cadastral surveying. By using laser pulses to measure distances, LiDAR creates highly accurate 3D representations of the Earth’s surface, surpassing traditional methods in terms of speed and efficiency. This study investigated LiDAR’s effectiveness in rural cadastral mapping, addressing the limitations of traditional techniques like total stations and GNSS. Using FARO TLS and Leica RTK-GPS, researchers collected dense point cloud data and processed it using FARO Scene and Cloud Compare software. LiDAR demonstrated exceptional accuracy, achieving a mean square error of $\pm 0.047 \mathrm{~m}$, well within the acceptable limit for cadastral applications. Additionally, it significantly improved operational efficiency, reducing survey time and personnel requirements by approximately five times. These results highlight LiDAR’s potential to revolutionize cadastral mapping and enhance land administration in rural areas.
