Randomized trial evaluates spatial accuracy of LiDAR data in Italy, indicating reliability for national applications.

This study aims to evaluate the quality and accuracy of nationwide aerial LiDAR data for effective land management and infrastructure planning.
Employed a fully automated quality assurance framework for nationwide LiDAR data.
Analyzed geometric consistency by extracting 100 × 100 m patches and computing point-to-point distances.
Assessed plano-altimetric accuracy through comparisons with terrestrial laser scanning data in control areas.
The automated framework demonstrated robustness in evaluating spatial accuracy across different areas.
Error estimation was rigorous, revealing significant discrepancies in the dataset.
High precision in the national LiDAR product was confirmed, supporting future large-scale geospatial acquisitions.

Casella et al. (2026) studied this question.
