#14 State and Trends in Airborne LiDAR (full day)
Due to the tremendous progress in Airborne LiDAR (Light Detection And Ranging), new sensors and technologies have emerged in recent years. Beyond the constant increase of scan rates and progress in waveform analysis, current trends are:
- Single Photon LiDAR (SPL) enabling higher areal coverage compared to conventional scanners at the price of a higher noise level and outlier rate.
- UAV LiDAR: Compact laser scanners mounted on UAV-platforms enable unprecedented spatial resolution and new applications. Expensive survey-grade sensors currently compete with low-cost systems.
- Hybrid sensor systems comprising laser scanners and cameras enable simultaneous acquisition of scans and images and, thus, fusion of data from LiDAR and image matching.
The full-day tutorial features a theory and a hands-on part. Overview lectures introduce the theory of the stated technologies for mapping both, topography and bathymetry. In the hands-on part of the tutorial, the participants will process LiDAR data from modern sensors and derive products like DSMs and DTMs, 3D-meshes, water depth maps, etc. using scientific, commercial, and open source software (OPALS, SURE, CloudCompare, etc.).
