Full-waveform ALS workshop - Radiometric Calibration of Full-Waveform Small-Footprint Airborne Laser Scanner Data

Fifth Presentation

Christian Briese, Hubert Lehner: Radiometric Calibration of Full-Waveform Small-Footprint Airborne Laser Scanner Data






Conclusions:

• Radiometric calibration essential for adequate use of full-waveform ALS
sensors
• Practical methods have become available
• Further R&D
- Radiometric accuracy (in %)
- Internal calibration (monitoring of sensor functions)
- Deviations from radar equation
- Object signatures at 1 μm, 1.5 μm and other ALS frequencies
