Although Mobile Laser Scanning (MLS) has significantly enhanced the efficiency of urban topographic mapping, its performance in dense urban environments remains subject to multiple operational constraints. This paper examines key factors affecting data reliability, including GNSS signal degradation, IMU drift, occlusions, and point density variability, and analyzes their influence on point cloud integrity and the accuracy of the resulting digital topographic plan. Positioning accuracy may reach approximately 2–3 cm under favorable conditions, but can degrade to decimeter-level deviations in dense urban environments due to signal instability and trajectory uncertainties. Methodological considerations are proposed to improve robustness and quality control in MLS-based urban mapping.
