What maximum beam inclination is used by airborne lidar technology?

Airborne lidar technology typically operates at a maximum beam inclination of 15 degrees. This inclination allows for effective scanning of the terrain while maintaining the ability to capture high-resolution topographic data. The 15-degree angle is optimal as it balances the need for sufficient coverage of the survey area with the precision required for accurately measuring elevation and other surface features.

At this inclination, the lidar system can maintain a good point density over varied terrain conditions while minimizing distortion of the data caused by excessive angles. This ensures reliable mapping of features, such as vegetation and surface types, which is crucial in hydrographic surveys. The design parameters for airborne lidar are carefully calibrated to maximize efficiency and data quality within this established operational limit.
